Importing data from CDs
Users new to audio editing are often surprised to find that they cannot import the audio from CDs into Audacity with the bits on the disc. That is why when you look at an audio CD in a file manager like Windows Explorer, each CD track will appear only as a small .cda "file" 44 bytes in size, which is merely header information for the stream.command. In fact, most operating systems do not actually allow the import of data from the CD tracks into applications, because audio CDs do not have files or a file system like computer media, but consist essentially of a stream of
In order to import tracks from an audio CD, you must first usually extract (or "rip") the tracks to a WAV or AIFF audio file using CD extraction software; then you can import those WAV or AIFF files into Audacity with the usualcommand.
|Do not extract the CD to smaller-sized MP3 format if you want to edit the audio in Audacity, because every time you export an MP3 file, some of the quality is lost. Extract to WAV or AIFF which are lossless. You can always export to MP3 from Audacity after editing, but do that only once for the finished audio.|
Audio CDs may be ripped to WAV with Windows Media Player 11 or 12 (clickand choose "WAV (Lossless)" in the Format dropdown in "Rip Settings"). Earlier versions of Windows Media Player are not appropriate for extracting CD audio for editing in Audacity, because they are unable to extract to WAV.
Alternatively the Windows version of iTunes (which is free to download) may be used to extract audio CDs to WAV or AIFF.
Mac users have a quick way to import CDs, because when a CD is put in the drive, the CDA tracks are mounted as AIFF files in the Finder. It's thus possible to either drag the AIFF files from the Finder into Audacity, or use thecommand, instead of extracting the audio.
