About audio files

You can import many audio file formats into your project, including WAV, AIFF, .cdda, MP3, and AAC. Although Motion is not a full-featured audio editing and mixing environment like GarageBand or Logic Pro, you can import music clips, dialogue, and sound effects. If you import a QuickTime file with mono or stereo tracks of audio, the audio appears in the Audio Timeline.

You can import audio clips with various sample rates and bit depths. When you do, Motion resamples audio tracks to the sample rate and bit depth used by your computer. The default is 16-bit, 44.1 kHz float for the built-in audio interface. If you use a third-party audio interface, audio is remixed to the sample rate and bit depth used by that device.

You can import audio files with sample rates up to 192 kHz and with bit depths up to 32 bits. Mono and stereo files are supported. Multichannel audio files are also supported.

For more information about file formats Motion supports, see Supported media formats. For more information on using audio in Motion, see Audio overview.

A seamless way to browse for and import music from your iTunes library is to use the Music category in the Motion Library. For more information, see Add iTunes and photo files from the Library.
