Part 2. More Information About AIFF Audio and M4A

1. What are AIFF and M4A?

AIFF (short for Audio Interchange File Format) is a format developed by Apple Inc. in 1998 and is an audio format standard used for storing sound data for personal computers and other electronic audio devices. The extension for AIFF is .aiff or .aif, it always used to store uncompressed, so that why it needs more disk space to store the file.


M4A is a file extension for an audio encoded with advanced audio coding (AAC) which is a lossy compression format. The extension of M4A is .m4a and stands for MPEG 4 Audio. It used to store compressed audio and video data.


2. What is the difference between AIFF and M4A?

AIFF occupies more disk space because it always used to store the uncompressed audio files, so that would be a problem if you want to store as many audio files as you can. While on the contrary, M4A file format is used to store the compressed one, namely, it occupies less disk space, which is good for those who are big fan of audio files.


Furthermore, AIFF is a lossless format, meaning that all audio information is stored in the file and nothing is lost. On the contrary, M4A is a lossy compression algorithm that discards the least important data. But M4A can store more audio files than the AIFF one.
