AIFF — Audio Interchange File Format
| File extension | .aiff .aif |

| File category | audio |

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.

AMR (Adaptive Multi Rate): adaptive encoding with variable bitrate

This information compression format allows for optimizing speech encoding. Files in the Adaptive Multi Rate format can be created using phones and smartphones. AMR files are mostly used for voice recordings. The main advantages of the format are the large number of encoding and decoding rates, as well as the small size of the resulting content. With the help of appropriate software, an Adaptive Multi Rate file can be converted into any other audio format.
