Exporting audio for loading into iTunes
Follow the below steps to export audio for adding to iTunes.
 * 1) Use the  command or  in Audacity (or ).
 * 2) Choose the export format in the Export dialog, to export the particular format you want your file(s) to be in (the best choices are WAV, AIFF, MP3 or AAC).
 * 3) Move the file(s) into iTunes from the location you exported it to, using the iTunes File > Add File to Library... (or File > Add Folder to Library...) command.

What format should I export to?
AAC is the default format set in iTunes and the format Apple uses for audio files sold from the iTunes Store, so is the most obvious choice if you solely use Apple products. MP3 should be considered if you think that in the future you may wish to switch to an alternative portable music player or phone. If you have plenty of storage space on your device or a relatively small music library you may wish to consider the larger lossless WAV or AIFF formats.

There are several advantages to using a compressed format on iPods and iPhones. The two main benefits are that you can fit many more songs into the device (for 256 kbps files you can fit about 10 times as many songs) and compressed files improve battery life, because disk reads are relatively heavy on battery power.

If you choose lossy formats (MP3 or AAC) the minimum bitrate setting you should use for music is 160 kbps, though 256 kbps is probably to be preferred - and in use on an iPod is unlikely to be distinguishable from WAV or AIFF (or Apple Lossless). For speech 128 kbps or even 64 kbps can be used as the bitrate if preferred.

WAV or AIFF (universal support, lossless, best for CD burning)
If you want a perfect lossless copy of your audio, or to burn it in iTunes to an audio CD for playing on any CD player, you should choose WAV or AIFF. It is strongly recommended you export a standard "CD quality" 44100 Hz, 16-bit stereo WAV or AIFF to make sure iTunes understands the file. This means:


 * 1) Ensure Project Rate at the bottom left of the Audacity project window is set to "44100" Hz.
 * 2) Select  (or ) then select "WAV (Microsoft) signed 16-bit PCM" or "AIFF (Apple) signed 16-bit PCM" in the export window
 * 3) * If you want a stereo export but your Project does not already contain a stereo track, click Tracks > Add New > Stereo Track.

See Burning music files to a CD if you are only interested in burning a CD.

MP3 (universal support, small files, lossy)
If you want to distribute your files on the internet (for example as a podcast), you should choose MP3 as the Format in the Export dialog, as this is a space-saving (although slightly lossy) format that anyone should be able to play. To export as MP3 from Audacity you need first to download the LAME encoder and point Audacity to it (see Lame Installation).

If you want to put the files on an iPod, or simply store them in iTunes in a compact form, MP3 is also a good choice. However, there are some reports that when run on battery, recent iPods can struggle or crash when playing MP3s created in applications other than iTunes. So you may want to export as WAV or AIFF from Audacity and convert the files to MP3 in iTunes instead.

AAC (Apple proprietary, small files, lossy)
Apple's proprietary format produces lossy, small, files similar to MP3, they are approximately the same quality as MP3 for a slightly smaller file size. The files are created with the .m4a extension.

AAC is useful for iPod or storage in iTunes due to its small file size and reduced disk occupancy, particularly if you have an iPod with a small disk. The minimum bitrate setting you should use for music is 160 kpbs though 256 kbps is probably to be preferred and in use on an iPod is unlikely to be distinguishable from WAV or AIFF (or Apple Lossless).

Audacity can export directly to AAC if you install the optional FFmpeg library. To export to AAC choose M4A (AAC) Files (FFmpeg) in the Export Audio window then type the file name. If you are exporting an AAC file for mobile devices, you can add the M4R (ringtone) or 3GP extension after the file name and dot as required by the device.

Apple Lossless (Apple proprietary, lossless, smaller than WAV/AIFF)
Apple Lossless Encoding (sometimes referred to as ALAC - Apple Lossless Audio Codec) is also an Apple proprietary format. Apple Lossless is, as the name suggests, Apple's size-compressed lossless codec. Like AAC it also uses files with the M4A extension.

Apple Lossless Encoder is quite similar to FLAC, producing larger files than AAC or MP3 but smaller than WAV. Typically an Apple Lossless file is around half the size of an equivalent WAV file and more than three times the size of an equivalent AAC 256 kbps file.

You cannot export directly to Apple Lossless from the Export Audio dialog. Instead, on Windows and Linux, install the optional FFmpeg library. On Mac OS X, search for and download a standalone "ffmpeg" binary online. Then export using the (external program) choice. Click the button, then enter the following command: ffmpeg -i - -acodec alac "%f" On Mac OS X, you must give the full path to ffmpeg enclosed in quotes, instead of just "ffmpeg".

Finally in the Export Audio dialog, add the M4A extension after the file name and dot. See Exporting to an External Program for more help.

Format conversion in iTunes
Alternatively you can export to WAV or AIFF and convert to MP3, AAC or Apple Lossless in iTunes: After creating the MP3, AAC or Apple Lossless version you should delete the original WAV or AIFF files to save disk space, as iTunes does not do this for you automatically.
 * 1) Click (or  on Mac)
 * 2) Click on the leftmost "General" tab
 * 3) Click the button
 * 4) In the "Import Using" dropdown, choose "MP3 Encoder", "AAC Encoder" or "Apple Lossless Encoder" as required
 * 5) Click OK and OK
 * 6) Select the file to be converted, then right-click or control-click over it and choose "Create MP3 Version", "Create AAC Version" or "Create Apple Lossless Version" as appropriate.

Export location
You can choose any location for the export such as a "Music" folder on your Desktop or even the iTunes "Music" folder if you have one. However you must still import this file from the exported location into the iTunes Library (which makes it visible in Library > Music on the left hand panel of iTunes).

There are two ways to import your exported audio files into iTunes:
 * Use the or  command from within iTunes, to add a single audio file or a folder of audio files.
 * Select in iTunes and drag the file from the location you exported it to, into the iTunes window. If you just want to burn the files to CD, it's best to drag them directly into an iTunes Playlist in the left-hand panel.
