In this section, you will learn some facts about AC3 and AIFF. This also includes features of each audio format. If you are wondering about these formats, you will certainly find the information below helpful.

What is an AC3 file?

AC3 is widely accepted on DVD media and DTV. It is a highly compressed format that is small in file size while the sound effect and quality are faithfully preserved as the original DVD. In actual fact, most HDTVs also take it as the standard audio format as it produces vivid and true-to-like sound in HD signal television. Quality-wise, AC3 can produce 6-channel surround sound yet only supports 5.1 channels and is limited to 448kbps when being played to audio CDs.

What is an AIFF file?

AIFF is also an audio file format used in Macintosh OS that adopts a lossless compression technology. It is short for Audio Interchange File Format files developed by Apple in 1988. Since it uses a lossless compression tech, you can expect high quality yet it takes up more space significantly. On the other hand, AIFF comes with a compressed counterpart also known as AIFC. Hence, if you need to optimize your AC3 files for playing in Mac systems, then AIFF is the ideal format. Below we will tackle the absolute solutions to help you convert AC3 to AIFF.
