AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple Inc. in 1988, based on EA IFF 85. AIFF stores raw PCM audio without compression, preserving full audio fidelity — one minute of stereo CD-quality audio (44.1 kHz, 16-bit) occupies approximately 10 MB. The format supports sample depths from 8 to 32 bits and sampling rates up to 192 kHz, making it a standard choice for professional audio production on macOS. AIFF is natively compatible with Apple iTunes, Logic Pro, GarageBand, and most professional DAWs. An extended variant, AIFF-C (AIFC), supports optional compressed audio codecs.

The M4R format is used on Apple's mobile devices, mostly for storing ringtones. You can create an M4R file by converting other formats or downloading it from the iTunes Store. M4R is based on the standardized MPEG-4 format and is commonly encoded with AAC audio. One of its strengths is good sound quality at a small file size.
