Mac & PC: How to Convert AC3 to MP3, WMA, AAC, OGG, etc.

There isn't a common standard for audio formats. If you have a library of music files on media collection, you will find that those audio files come in a number of different formats. While some are lossless such as FLAC, AIFF, WAV, some others may be in lossy AC3, MP3, AAC, and WMA format. In today's discussion, we're going to focus on one of those formats — AC3, how can you convert AC3 on Mac or PC machine into something more readable.

What is AC3 (Audio Coding 3)

AC3 is a audio lossy compression standard that's developed by Dolby Laboratories for (5.1) surround sound audio files. Audio saved in .ac3 will result in a smaller size compared to the original files, but loss of the original data during compression. Dolby Digital AC3 audio is generally used on Blu-ray, DVD, HDTV broadcast and other digital video formats. In the format, the AC-3 bitstream is interleaved with the video and control bitstreams.

Audio codec AC3 however, is distributed under the license from Dolby, which leads many of applications drop the playback support of it. To solve this issue, you have to convert audio in .ac3 to other manageable audio files like mp3, m4r, wma, dts, ogg and others. If you have an Apple device, you might want to use AAC audio instead.
