Τι μπορώ να κάνω αν έχω προβλήματα στην λήψη ή την εγκατάσταση του Audacity;
Αν δεν μπορείτε να κατεβάσετε το Audacity ή αν το αρχείο εγκατάστασης είναι κατεστραμμένο, προσπαθήστε να το κατεβάσετε από τους εναλλακτικούς διακομιστές μας. Στη σελίδα που θα σας ανοίξει, κάνετε κλικ στον σύνδεσμο που λέει "Looking for the latest version?". Αν επιθυμείτε την zip έκδοση του Audacity για Mac ή Windows, κάνετε κλικ στον σύνδεσμο του φακέλου "audacity", και στην σελίδα που θα σας ανοίξει κάνετε κλικ στον πρώτο φάκελο της λίστας που περιέχει και την τελευταία έκδοση.

Αν κατεβάσετε κάποιο κατεστραμένο αρχείο, είναι καλή ιδέα να καθαρίσετε την λίστα των λήψεων ή την προσωρινή μνήμη του περιηγητή σας ή του διαχειριστή λήψεων, πριν το κατεβάσετε ξανά.

Τι μπορώ να κάνω αν βρεθούν σφάλματα κατά το χτίσιμο του Audacity;
Το Audacity παρέχει προγράμματα εγκατάστασης που το περιέχουν έτοιμο και χτισμένο για Windows και Mac, αλλά γίνεται να το χτίσετε από τον πηγαίο κώδικα για κάθε πλατφόρμα. Με λίγη γνώση, το χτίσιμο είναι ένας καλός τρόπος για να προσαρμόσετε το Audacity στα μέτρα σας! Για βοήθεια, παρακαλούμε δείτε τα έγγραφα του wiki για τα Windows, Mac και Linux.

Αν δεν καταφέρνετε να χτίσετε το Audacity, παρακαλούμε ρωτήστε στην κατηγορία Compiling Audacity του φόρουμ.


 * Παρακαλούμε πείτε μας αν προσπαθείτε να το χτίσετε από μια έκδοση tarball ή από το Audacity HEAD.
 * Στα Windows, δώστε μας όλες τις περιπτώσεις των σφαλμάτων(ERROR) που εμφανίζει το παράθυρο του Visual Studio(συμπεριλαμβανομένων των σφαλμάτων Linker).
 * Στα Mac και Linux, δώστε μας τις τελευταίες γραμμές που αποτυγχάνουν όταν κάνετε configure ή make.
 * Στα Linux, πείτε μας ποια διανομή και έκδοση χρησιμοποιείτε (π.χ. Ubuntu 14.04 ή Fedora 20).

Windows: Πώς εγκαθιστώ το Audacity; Πρέπει να κάνω πρώτα απεγκατάσταση της προηγούμενης έκδοσης;
Αποθήκευση: Πηγαίνετε στη σελίδα των λήψεων και κάντε αριστερό κλικ στο σύνδεσμο του "πρόγραμματος εγκατάστασης" για να το αποθηκεύσετε στον υπολογιστή σας. Ελέγξτε τις προτιμήσεις του περιηγητή σας, αν είναι απαραίτητο, για να βρείτε που αποθηκεύονται οι λήψεις σας. Εναλλακτικά, κάντε δεξί κλικ στον σύνδεσμο, "Save Target As" ή "Save Link As" και επιλέξτε την τοποθεσία που επιθυμείτε να αποθηκεύσετε το αρχείο. Στη συνέχεια κάντε διπλό κλικ στο κατεβασμένο αρχείο που έχει επέκταση .exe για να ανοίξει το πρόγραμμα εγκατάστασης. Πρέπει να έχετε δικαιώματα διαχειριστή στον υπολογιστή για να το κάνετε αυτό, αλλιώς ακολουθήστε τα μηνύματα που θα σας εμφανιστούν για να αποκτήσετε δικαιώματα και να ξεκινήσει η εγκατάσταση.

Εκτέλεση: Στον Internet Explorer και σε άλλους περιηγητές, μπορείτε να πατήσετε αριστερό κλικ στο σύνδεσμο του "προγράμματος εγκατάστασης" και να επιλέξετε "εκτέλεση(Run)" του αρχείου. Με αυτή την επιλογή ξεκινάει αμέσως η εγκατάσταση. Σημείωση: Κάποια εγκατεστημένα λογισμικά ασφαλείας μπορεί να ζητήσουν την άδειά σας ή να μπλοκάρουν το πρόγραμμα εγκατάστασης επειδή το τρέχετε από προσωρινό χώρο του υπολογιστή.

Αναβάθμιση μιας προηγούμενης έκδοσης: Αν πάτε να εγκαταστήσετε μια νέα έκδοση του Audacity, ενώ υπάρχει ήδη εγκατεστημένη μια παλιά, το πρόγραμμα εγκατάστασης θα σας προσφέρει την επιλογή να γίνει η νέα εγκατάσταση στον ίδιο φάκελο με την παλιά. Αν η παλιά εγκατάσταση ήταν η έκδοση 1.2 ή 2.x, τότε ο φάκελος εγκατάστασης είναι από προεπιλογή (ή  στα 64-bit Windows). Αν δεν αλλάξετε τον φάκελο εγκατάστασης, το Audacity θα εγκατασταθεί πάνω από την προηγούμενη έκδοση 1.2 or 2.x, και όλα τα προηγούμενα πρόσθετα που είχατε στον φάκελο "Plug-Ins" θα είναι διαθέσιμα. Αν η προηγούμενη έκδοση ήταν η 1.3.x, κάντε απεγκατάσταση την 1.3 πριν εγκαταστήσετε την έκδοση 2.x. Μετά την απεγκατάσταση της 1.3, όλα τα επιπλέον πρόσθετα που είχατε σε εκείνη την έκδοση θα παραμείνουν, και μπορείτε να τα μετακινήσετε στον φάκελο "Plug-Ins" της νέας εγκατάστασης.

Αναβάθμιση προαιρετικών βιβλιοθηκών Αν αναβαθμίζετε από την έκδοση 1.3.6 ή κάποια παλαιότερη, θα πρέπει να αναβαθμίσετε και στην τελευταία LAME βιβλιοθήκη κωδικοποίησης MP3. Διαφορετικά δεν χρειάζεται να αναβαθμίσετε το Lame ή το FFmpeg εκτός αν αναφέρεται κάτι τέτοιο στις σημειώσεις της έκδοσης για την νέα έκδοση του Audacity.

Windows: How can I fix "Application configuration incorrect" when first launching Audacity after installation?
You may see the error Application configuration incorrect or error 14001 when launching Audacity after installation. This mainly affects some Windows XP or 2000 machines. This can be fixed by downloading and installing the appropriate Microsoft "Redistributable Package" as follows: Be sure to get the correct package according to whether you have 32-bit or 64-bit Windows. To check if you have 64-bit Windows, right-click over My Computer and choose Properties. If 64-bit is not mentioned, you have 32-bit.
 * Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) for 32-bit Windows
 * Microsoft Visual C++ 2008 SP1 Redistributable Package (x64) for 64-bit Windows.

Windows: How do I uninstall Audacity?
Audacity can be uninstalled by choosing "Add/Remove Programs" or "Uninstall a program" in the Windows Control Panel. Select "Audacity" from the list and follow the instructions which will launch the Audacity uninstall program. Make sure you quit Audacity before uninstalling, or you will receive errors that some files could not be removed.

If the Control Panel cannot uninstall Audacity, open the folder in which you installed Audacity and double-click "unins000.exe" (this file might have other numbers in the name). This requires "unins000.dat" (or similar) to be present in the installation folder.

If you still cannot uninstall Audacity, download the installer again. Install Audacity to the same location you installed it to before (which happens by default). This will replace the uninstall files with good copies, then you can run the uninstaller again.

Uninstallation leaves your Audacity settings intact, in case you want to install Audacity again at some time in the future. If you want to remove your settings as well, delete Audacity's folder for application data whose location is given here.

Mac OS X: Why do I see "unidentified developer", "Mac App Store" or "damaged" messages when I launch Audacity?
On OS X 10.7.5 and later, the Apple Gatekeeper feature controls launching of applications downloaded from the internet. If Gatekeeper won't launch Audacity because it is "from an unidentified developer" or "not downloaded from the Mac App Store", right-click or control-click on the Audacity application in Finder, choose "Open", then in the dialog box that appears, choose "Open". You should then be able to launch Audacity normally on subsequent occasions.

Occasionally, you may see an error message that "Audacity is damaged and can't be opened. You should move it to the Trash." If this message persists when you right-click or control-click over Audacity, open. Under the header "Allow applications downloaded from:", choose "Anywhere". Audacity should now launch. It would now be advisable to change the "Anywhere" preference back to a more restrictive setting.

How can I solve Audacity not appearing or crashing every time I launch it?
VST plug-ins (Windows and Mac OS X)

If the hang or crash occurs after pressing on the Install VST Effects dialog, a  VST effect is probably conflicting with Audacity.

You can restart Audacity then use the VST dialog to do one of the following.
 * Click to load none of the effects but be presented with the installation dialog again at next Audacity launch.
 * Uncheck all (or individual) VST effects to prevent them loading, then click . The VST effects you uncheck will not load again until you set "Rescan VST effects..." in Effects Preferences and restart Audacity.

To assist in identifying an errant plug-in, you can inspect the pluginregistry.cfg file in the Audacity folder for application data. This file will list which VST plug-ins Audacity had managed to load before it crashed. On Mac OS X, you can identify a VST plug-in which crashed from the Mac crash report. To view saved reports, open Finder, choose Go > Go to Folder then type ~/Library/Logs/DiagnosticReports/ (or ~/Library/Logs/CrashReporter/ on OS X 10.4 and 10.5).

Alternatively if you have VST plug-ins in system VST folders that you can't or don't want to use in Audacity, you could move those folders to your Desktop when you want Audacity to scan for VST plug-ins. After the Audacity scan, move the folders back to their system location so that they will be available for other programs.

Incompatible audio device or audio drivers 

If the Audacity hang or crash occurred after you added or enabled a new audio device, try removing or disabling that device (or updating its drivers) then restart Audacity. If the problem occurred after a driver update, try rolling back to the previous set of drivers. On Windows, you can revert driver changes caused by Windows Update.

If the entire computer crashes, reboots or displays a blue screen message when you launch Audacity, this is almost always due to a bad or mismatched audio driver (or due to a system driver conflicting with your sound device). You can inspect the memory dump of the computer to identify the source of the problem.

Resetting Preferences

The Audacity window could also fail to appear due to some Audacity configuration problem. To solve this, try resetting the Audacity Preferences. Conflicts with other programs such as security or anti-virus applications can occasionally cause Audacity not to launch. Try turning off some of the more advanced behavior detection settings in the security program, or add an exception to the program's settings to make Audacity a trusted application.

How do I reset my Audacity settings?
Uninstalling Audacity does not automatically repair or reset your settings in Audacity Preferences. If you are trying to fix a problem with Audacity, take one of the following actions.
 * Quit Audacity and reset Preferences using the audacity.cfg settings file. There is then no need to uninstall and re-install.
 * Alternatively, Windows users may run the installer and in the "Select Additional Tasks" screen, put a check in the "Reset Preferences" box. Complete the installation. On launching Audacity, a dialog will appear where you can confirm if you want to reset preferences just this once, or not.

Windows

 * 1) Go to the external LAME download page Left-click this link, do not right-click.
 * 2) Directly underneath "For FFMpeg/LAME on Windows", left-click the link Lame v3.99.3 for Windows.exe and save the file anywhere on your computer.
 * 3) Double-click "Lame v3.99.3 for Windows.exe" to launch it (you can safely ignore any warnings that the "publisher could not be verified").
 * 4) Follow the Setup instructions to install LAME for Audacity, making sure not to change the offered installation location of "C:\Program Files\Lame for Audacity" (or "C:\Program Files (x86)\Lame for Audacity" on a 64-bit version of Windows).

You should now be able to export MP3s without any further configuration, choosing File > Export Audio... then selecting "MP3 Files" in the Export Audio Dialog.

Troubleshooting

Occasionally, there may be a conflict where Audacity still tries to detect the path to an older lame_enc.dll file. To correct this: Ensure there are no older versions of lame_enc.dll in any locations where Audacity detects it, namely:  C:\Program Files\Lame for Audacity or C:\Program Files (x86)\Lame for Audacity (this is where the installer puts the new .dll)  the Audacity installation folder (usually C:\Program Files\Audacity or C:\Program Files (x86)\Audacity'''), or in the Plug-Ins folder inside that.  Exit Audacity and navigate to the audacity.cfg preferences file at:  Windows 2000/XP: Documents and Settings\ \Application Data\Audacity\audacity.cfg Windows Vista/7: Users\ \AppData\Roaming\Audacity\audacity.cfg.</li></ul>  Open audacity.cfg in a text editor such as Notepad, and delete the two lines starting with: [MP3] MP3LibPath= </li></ul>  Save the changes to audacity.cfg and restart Audacity </li></ol> In order to see audacity.cfg, you may need to set the operating system to show hidden files and folders. See instructions for Windows 7 and Windows versions before 7.

Mac OS X

 * Installer
 * 1) Go to the external LAME download page.
 * 2) Download Lame Library v3.98.2 for Audacity on OSX.dmg.
 * 3) When you have finished downloading, double-click the .dmg to mount it, then go to the Finder (in Safari, the "Lame Library v3.98.2 for Audacity" virtual disk image will be extracted and mounted automatically after downloading).
 * 4) Double-click "Lame Library v3.98.2 for Audacity.pkg"; the standard OS X Installer will start
 * 5) Click through the steps in the Installer, accepting the defaults in all cases; this will install the LAME binary "libmp3lame.dylib" in /usr/local/lib/audacity.
 * 6) Audacity should detect LAME automatically when you export as MP3. If Audacity cannot find LAME:
 * 7) Click Audacity > Preferences then choose "Libraries" on the left.
 * 8) Click "Locate..." under "MP3 Export Library", then "Browse..." in the "Locate Lame" dialog.
 * 9) The "Where is libmp3lame.dylib?" window will open at /usr/local/lib/audacity; select "libmp3lame.dylib", click "Open" then "OK" and "OK".

<div id="maclame_zip">
 * Alternative zip download for Lame 3.98.2
 * 1) Download http://lame1.buanzo.com.ar/Lame_Library_v3.98.2_for_Audacity_on_OSX.zip from the external download website.
 * 2) Extract the contents of the zip to a folder called "Lame_Library_v3.98.2_for_Audacity_on_OSX" anywhere you have full permissions (such as your Desktop).
 * 3) Click Audacity > Preferences then choose "Libraries" on the left.
 * 4) Click "Locate..." under "MP3 Export Library", then "Browse..." in the "Locate Lame" dialog.
 * 5) Navigate to and open the folder you extracted the zip to, select "libmp3lame.dylib", click "Open" then "OK" and "OK".

This is a good solution if Audacity does not recognize or work correctly with libmp3lame.dylib when installed to /usr/local/lib/audacity.

You should now be able to export MP3s without any further configuration, choosing File > Export Audio... then selecting "MP3 Files" in the Export Audio Dialog.

In case of difficulty, or if you have an older version of Audacity, please view our detailed instructions on the Audacity Wiki.

Linux/Unix
Some Linux distributions (for example, Ubuntu) now package Audacity with MP3 encoding and FFmpeg support already linked dynamically to the relevant system libraries. In these packaged builds there is no need to locate LAME or FFmpeg, so Audacity will have no "Libraries" Preferences. Most distributions have some sort of package manager that fetches software packages from the Internet and installs them for you. Open that package manager, search for LAME, and install it if it is not already installed.
 * Users compiling Audacity from source code can similarly remove the "Libraries" Preferences by configuring Audacity with --disable-dynamic-loading then build Audacity linked to both system LAME and FFmpeg. Otherwise, users building Audacity from source must locate a compatible build of LAME in the "Libraries" Preferences as below.

Installing LAME on Ubuntu 11.10 and later
In Ubuntu 11.10 and later the default package manager is the "Ubuntu Software Center". It is often most convenient to install the "Ubuntu Restricted Extras" as this includes LAME, FFmpeg and other useful media encoding/decoding tools.

If you wish to install only the LAME package required for MP3 export, search for LAME in the Ubuntu Software Center and install it.

Installing LAME on other Debian-based systems
The following are detailed instructions for installing LAME using the Synaptic package manager on recent Debian-based systems and in Ubuntu 11.04 and earlier.


 * 1) Open Synaptic:
 * 2) *In GNOME (the default desktop environment for many Debian-based systems), access Synaptic by clicking System > Administration
 * 3) *In KDE there will be a similar menu accessible from the bottom-left of the screen
 * 4) Enter the root password when asked for it.
 * 5) In the Synaptic window, choose "Settings", then “Repositories”
 * 6) In the "distribution Software" tab, check the box for "non free" (on Ubuntu based systems this is called "multiverse"), then hit the Close button.
 * 7) Back in the main Synaptic Window, type “lame” in the "Quick search" box.
 * 8) The search results will show the packages “lame” and “libmp3lame0” at the top of the list; mark both for installation by double-clicking.
 * 9) Click "Apply", and on “OK” for any warnings; the LAME software will automatically download and install.
 * 10) Right-click over the entry for "libmp3lame0" > Properties
 * 11) On the "Installed Files" tab, note the location of "libmp3lame.so.0", probably at /usr/lib/libmp3lame.so.0
 * 12) Close all the Synaptic windows

<div id="locate_linlame">

Locating LAME

 * 1) Open Audacity, click Edit > Preferences then on "Libraries" in the list on the left
 * 2) In "MP3 Export Library" check if a LAME version number displays to right of "MP3 Library Version". If so, LAME has been detected and you should now be able to export MP3 and skip the remainder of these instructions. If the MP3 Library is stated as "not found":
 * 3) Click the "Locate...” button
 * 4) In the "Locate Lame" dialog that appears, click "Browse"
 * 5) In the "Where is libmp3lame.so.0?" dialog, navigate to the location you noted in step 9, select "libmp3lame.so.0", click "Open", then "OK" and "OK" to exit Preferences

If your distribution does not have a LAME package, please view these instructions on the Audacity Wiki.

How do I download and install the FFmpeg Import/Export Library?

Windows

 * 1) Go to the external download page Left-click this link, do not right-click.
 * 2) Look for "For FFmpeg/LAME on Windows", then a few lines under that, left-click the link FFmpeg_v0.6.2_for_Audacity_on_Windows.exe and save the file anywhere on your computer.
 * 3) Double-click "FFmpeg_v0.6.2_for_Audacity_on_Windows.exe" to launch the installer (you can safely ignore any warnings that the "publisher could not be verified").
 * 4) Read the License and click Next, Next and Install to install the required files to "C:\Program Files\FFmpeg for Audacity" (or "C:\Program Files (x86)\FFmpeg for Audacity" on a 64-bit version of Windows).
 * 5) Restart Audacity if it was running when you installed FFmpeg.
 * 6) If you have problems with Audacity detecting FFmpeg, follow the steps to manually locate FFmpeg.

<div id="winff_zip">
 * Alternative zip download for FFmpeg 0.6.2
 * 1) Download http://lame3.buanzo.com.ar/FFmpeg_v0.6.2_for_Audacity_on_Windows.zip from the external download website.
 * 2) Extract the contents to a folder called "FFmpeg_v0.6.2_for_Audacity_on_Windows" anywhere on your computer, then follow the instructions below to locate avformat-52.dll using the Libraries Preferences.

Mac OS X

 * Installer:
 * 1) Go to the external download page
 * 2) Download FFmpeg (0.6.2 OSX 10.4+ DMG)
 * 3) When you have finished downloading, double-click the .dmg to mount it, then go to the Finder (in Safari, the "FFmpeg Libraries for Audacity" virtual disk image will be extracted and mounted automatically after downloading).
 * 4) Double-click "FFmpeg Libraries for Audacity.pkg" to launch the standard OS X Installer.
 * 5) Click through the steps in the Installer, accepting the defaults in all cases; this will install the FFmpeg libraries in /usr/local/lib/audacity
 * 6) Restart Audacity if it was running when you installed FFmpeg
 * 7) If you have problems with Audacity detecting FFmpeg, follow the steps to manually locate FFmpeg.

<div id="macff_zip">
 * Alternative zip download for FFmpeg 0.6.2

This is a good solution if Audacity does not recognize or work correctly with libavformat-52.dylib when installed to /usr/local/lib/audacity.


 * You can also build Audacity from SVN and link to a system copy of FFmpeg built from source, using these instructions.

Linux/Unix
Some Linux distributions (for example, Ubuntu) now package Audacity with MP3 encoding and FFmpeg support already linked dynamically to the relevant system libraries. In these packaged builds there is no need to locate LAME or FFmpeg, so Audacity will have no "Libraries" Preferences. You may download (or build) a suitable FFmpeg library for your own purposes. To build, obtain the source code from the FFmpeg project. If you download a pre-built library, this might be either a "shared" or "static" build. A static build consists of a single libavformat library, whereas a shared build has at least three libraries (libavformat, libavcodec and libavutil). It is recommended to use a shared build, but Audacity will also work with a static build.
 * Users compiling Audacity from source code can similarly remove the "Libraries" Preferences by configuring Audacity with --disable-dynamic-loading then build Audacity linked to both system LAME and FFmpeg. Otherwise, users building Audacity from source must locate a compatible build of FFmpeg in the "Libraries" Preferences as below.

If you compile Audacity from source code, it will link to the installed FFmpeg headers, which should always be compatible with an installed FFmpeg binary.

Locating the FFmpeg library manually
If you installed FFmpeg while Audacity was running, or if you installed FFmpeg to a non-default location, Audacity will ask you to configure Preferences to locate the FFmpeg library. To do this, access Preferences then the "Libraries" tab on the left:
 * [[Image:Preferences Libraries notFound basic7.png|FFmpeg Locate... and Download... buttons]]

As seen in the image above, the "FFmpeg Library Version" will say "not found". To correct this:
 * 1) Click the "Locate..." button to right of "FFmpeg Library".
 * 2) If a "Success" message indicates Audacity has now automatically detected the library and asks if you want to detect them manually, click "No", then OK to close Preferences.
 * 3) If the "Locate FFmpeg" dialog appears, click "Browse...".
 * 4) Navigate to the avformat library, and select it. It may have different names, such as "avformat-52.dll" on Windows, "libavformat-52.dylib" on Mac or "libavformat.so.52" on Linux.
 * 5) Click "Open" then "OK", and "OK" again to close Preferences.

"FFmpeg Library Version" should now show a number. If not, you may have installed the wrong libraries. Click the "Download..." button to obtain the correct library for your operating system. You can also choose to see diagnostic information about FFmpeg detection.

Why do I receive an error when I export to an FFmpeg format?

If you receive a "cannot find audio codec" error when exporting to an FFmpeg format, the FFmpeg library you are linking to does not support this codec. To export to this format, you will need a build of the FFmpeg library that supports this codec.

Distributable libraries will not include support for AMR WB (wide band), due to licensing issues. Exporting to AMR WB will return the error "FFmpeg cannot find audio codec 0x 12001". To obtain AMR WB export support, you could build FFmpeg yourself from source and enable the relevant library in the configure step. back to top

<div id="vst_install">

How do I install VST plug-ins?
Audacity supports almost all VST effect plug-ins on Windows and Mac OS X. On first use, Audacity scans automatically for VST effects then presents you with an Install VST Effects dialog to choose which effects to load. The VST effects that you checkmark will be loaded when you click. The list will include any real-time VST effects or VST instrument (VSTi) plug-ins that are detected but neither of these are currently supported and so will not load even if you enable them in the dialog.

To install new VST effects, place them in the “Plug-ins” folder inside the Audacity installation folder. On Windows, this is usually under Program Files (or Program Files (x86) on 64-bit Windows); on Mac OS X, it is usually in the "Applications" folder. VST effects will also be found if they are added to (or already exist in) various system locations. To display the newly added plug-ins: There is no need to add the VST Enabler which was required by previous versions of Audacity.
 * 1) Go to the Effects Preferences
 * 2) Under "VST Effects", put a check mark in "Rescan VST effects next time Audacity is started"
 * 3) Restart Audacity then click OK in the "Install VST Effects" dialog to load your new plug-ins and any other VST effects which you checkmark.

Why do some VST plug-ins not work or display incorrectly?
On Windows and Mac OS X, Audacity will by default display VST effect plug-ins with a full graphical interface where the plug-in supplies this. Any plug-in that requires to be left open while processing audio will not work correctly. Real-time VST effects and VST instrument (VSTi) plug-ins are not currently supported.

If any plug-in displays incorrectly, you can uncheck "Display VST effects in graphical mode" in the Effects Preferences to display a simpler tabular interface for the plug-in (this also affects all other plug-ins).

If you experience a problem with a specific VST effect plug-in in Audacity, please contact us. See also: How do I install VST plug-ins?

<div id="linux_plug-ins">

How do I install plug-ins on Linux?
Audacity on GNU/Linux supports a large number of Nyquist, LADSPA, LV2 and VAMP effects. Although quite rare as native Linux effects, VST effects are now supported in Audacity on Linux. See VST Effects for how to install VST effects in Audacity. Audacity supports 64-bit effects in VST, LADSPA and VAMP format on 64-bit Linux systems (conversely, 32-bit plug-ins in those formats will not load into Audacity on 64-bit Linux).

Individual Nyquist and LADSPA plug-ins can be installed by putting the plug-ins into the Audacity "Plug-Ins" folder: These locations are usually set as read-only, so the plug-ins will need to be copied as root (for example, by issuing an appropriate root command in the terminal, or by using the terminal to open a file manager application with root permissions). Audacity installed from a repository package or compiled from source should automatically find LADSPA plug-ins installed in /usr/lib/ladspa. This may not be the case if you are compiling older source code. If necessary you can set an environment variable to indicate to Audacity where LADSPA plug-ins are installed. For Debian-based distributions this can be done by entering the following code at the command prompt (change to your account user name): export LADSPA_PATH=$LADSPA_PATH:/home/ /.ladspa:/usr/local/lib/ladspa:/usr/lib/ladspa If you wish this path to be set each time you boot, the LADSPA_PATH environment variable may be added to ~/.profile or this file may be created if it does not exist. An example of how to add the LADSPA_PATH environment variable: LADSPA_PATH=$LADSPA_PATH:/home/ /.ladspa:/usr/local/lib/ladspa:/usr/lib/ladspa export LADSPA_PATH For OpenSuse 64, LADSPA plug-ins may be found in /usr/lib64/ladspa. This path can be set by adding the following line to your /etc/environment file: LADSPA_PATH=/usr/lib64/ladspa
 * /usr/share/audacity/plug-ins if Audacity was installed from a repository package
 * /usr/local/share/audacity/plug-ins if you compiled Audacity from source code.

LV2 and VAMP plug-ins cannot be placed in the Audacity "Plug-Ins" folder or your .audacity-files folder. LV2 plug-ins should be installed by placing the complete .lv2 folder (not the individual files in that folder) in the root of ~/.lv2, /usr/local/lib/lv2, /usr/local/lib64/lv2, /usr/lib/lv2 or /usr/lib64/lv2. Alternatively the environment variable may be set as in this example: export LV2_PATH=$HOME/.lv2:/usr/local/lib/lv2:/usr/lib/lv2 VAMP plug-ins may be installed in $HOME/vamp, $HOME/.vamp, /usr/local/lib/vamp or /usr/lib/vamp. Alternatively the VAMP_PATH environment variable may be set to any of those specified VAMP installation directories. VAMP plug-ins will normally be placed in the Analyze Menu of Audacity.
