Understanding AIFF and FLAC file formats

AIFF (Audio Interchange File Format) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. Developed by Apple, it is commonly used on Mac systems and is known for its high-quality audio output, as it stores uncompressed audio data.

FLAC (Free Lossless Audio Codec) is an audio format similar to MP3, but lossless, meaning that audio is compressed without any loss in quality. This format is widely used for high-quality audio storage and is compatible with many devices and software.

Why convert AIFF to FLAC?
