AIFF Explained

AIFF stands for Audio Interchange File Format. This particular audio file is not compressed. When you view this file format on a PC, you will see .aif extension. You won’t be able to see that extension when you view it on a Mac.

You will find the following in an AIFF file format: channel information, raw audio data, bit depth, application-specific data areas, and sample rate. The AIFF file format results in an uncompressed pulse-code modulation file which means that it has relatively large file sizes. Nonetheless, it maintains a higher quality of sound.
