AIFF "Audio Interchange File Format" is a new audio format, and is used as a standard format for audio files in PCs. Includes CD-quality audio, which is stored in an uncompressed format without loss of close to file extension .WAV. Its special feature is that it allows you to place a sound wave along with additional information, in particular samply WaveTable (examples sounding instruments with synthesizer settings), which improves the quality of the final result.
This format is a copy of the WAV format but supports covers and tags with track information (Sample Rate: 44,100 kHz Sample Size: 16 bit Bit Rate: 1411 kbps).
AIFF stands for Audio Interchange File Format. Basically, an AIFF file has all the convenience of an MP3, containing metadata and cover art, with the audio quality of an uncompressed “lossless” format like WAV.
