Chapter 6. Audio Editing > Audio File Formats

Audio File Formats

Only two audio-only file formats are supported for editing within Final Cut Pro. Supported Audio formats include WAVE and AIFF files. To use a different file format, you must convert the original format, such as MP3 files, to a compatible format using the Pro version of the QuickTime Player (which is bundled with FCP 4 for free) or another audio application such as Pro Tools or even iTunes. You can even import a file, then export it as a supported file format from within Final Cut Pro choosing File/QuickTime Conversion, and selecting aiff and 48kHz as its file format. Then you import that file into Final Cut Pro for editing. Using compression is not a good idea. In fact, compressed audio files don't work with Final Cut Pro. Audio files are relatively small compared to the file size of video and graphics files in general. The higher the quality you preserve, the better the sound will be. Final Cut Pro converts these compressed files anyway, so just avoid using them.

The AIFF and WAV formats can be sampled at different rates. Sampling is the process used when you convert analog sound (like that which is created by a microphone) to digital audio files. The higher the sampling rate, the more samples that are taken, and thus the better the fidelity or sound reproduction of the audio files.
