Difference Between AIFF and MP3 ??
The most major difference between the AIFF and MP3 is compression. AIFF does not do compression while MP3 does. In fact, compression was the main draw that made MP3 very popular, especially with portable music devices. Compression reduces the file size of the song, or any audio data, allowing users to fit more files into a given memory capacity.
AIFF typically consumes 10MB for every minute of audio recording; not very practical for early portable devices with only 128MB of memory or even less. With MP3, the size can vary greatly depending on how much you compress and sizes of around 1MB per minute are not uncommon
