AC3 Audio Format AC3 Converter
The AC3 (Audio Codec 3) file format was developed by Dolby Laboratories, and is an audio format designed to support surround sound. The format can include up to six separate channels of audio output - one for each of the five speakers in a surround sound setup, plus one for a subwoofer. AC3 files use Dolby Digital lossy compression technology, which maintains sound quality even with a reduced file size.
Although this file format was originally developed for audio in cinemas, it now has many other uses, such as in digital video streaming and TV broadcasting, for DVD and Blu-ray discs, and for video game consoles. The format’s reduced file size makes it ideal for storing and distributing - e.g. on a DVD or Blu-ray disc. An AC3 file can be opened by many different media players, including Apple QuickTime, Windows Media Player, and VLC.

M4R Audio Format M4R Converter
The M4R format is an iPhone Ringtone File. The format was developed by Apple, and you can create M4R files using Apple iTunes. M4R files are similar to M4A music tracks, but they are clipped to 30 seconds to be used as ringtones. Once you create or download an M4R file and sync your iPhone, the track should automatically go into your ‘Sounds and Haptics’ library with all the other ringtones, rather than your main music library. You can also manually add M4R files while your phone is connected to another device.
If you’ve created an M4R file from a downloaded iTunes track, it’s probably protected by digital rights management (DRM), which stops you from sharing it with other users. If an M4R file does not have DRM protection, you can usually play it with VLC Media Player.
