About AIFF and MP3
audio/x-aiff
AIFF is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. Developed by Apple, it is uncompressed and lossless, similar to WAV.
audio/mpeg
MP3 is the most widely used audio compression format for music distribution. It reduces file size by removing frequencies less audible to the human ear. MP3 files are supported by virtually all audio players and devices, making them ideal for music sharing and streaming.
Conversion Notes
Audio conversion from AIFF to MP3 re-encodes at the highest quality setting appropriate for the target format. Lossless-to-lossy conversion (e.g., FLAC to MP3) is a one-way process — converting back to lossless does not recover the discarded information. Metadata tags (title, artist, album, track number) are mapped to the closest equivalent fields in the target format.
