CAF file format guideA short extension for Audio Interchange File Format. AIFF commonly stores uncompressed PCM audio for editing and interchange.
AIF and AIFF are extension variants. Tested output uses 16-bit big-endian PCM; sample conversion can alter precision.
AIF file format guideChoose the sample rate, trim range, and mono or stereo output. Compressed audio formats can discard detail; converting to a lossless format cannot restore sound already lost. Container support depends on the codec inside the file.
