AIFF (acronym for Audio Interchange File Format) is an audio format that contains uncompressed audio pulse-code modulations (PCM).
More popular on Macs than on computers running Windows, the AIFF format supports streaming several tracks from a computer to dedicated apps.
Because AIFF files are very suitable for burning on audio CDs, users will often convert their audio tracks to the AIFF format using specialized audio converters.
Prior to the actual conversion, users may also be able to modify the files' sample rate, bit rate or audio channel number.
Furthermore, audio editing apps that feature support for AIFF creation will enable users to select the output filename.
