About AIFF files
AIFF is Apple's uncompressed audio format, the Mac equivalent of WAV. GarageBand, Logic and many sample packs save AIFF, and the files are large: about 10 MB per minute of CD-quality stereo.
People convert AIFF to MP3 to share a mix, send a demo or put tracks on a phone. The MP3 is far smaller and plays on any device.
How we convert AIFF to MP3
- Encoder mode
- MP3 at variable bitrate quality level 2, averaging about 190 kbps.
- Sample rate
- Kept from the source unless you set 44.1 kHz or another rate.
- Tags
- Title, artist, album, year and genre can be written into the MP3.
- Loudness
- Normalize and volume options are available if a bounce came out too quiet.
Common problems and fixes
A mix bounced at 48 kHz plays at the wrong speed on an old device.
Set the sample rate to 44.1 kHz before you convert.
The demo is too quiet next to other tracks.
Turn on normalize to raise the level of the whole file.
You need the smallest file for a quick preview.
Pick 128 kbps. It is fine for a preview and much smaller than the default.
