Convert to AC3 Online Tool.
AC3 stands for Audio Codec 3, a comprehensive audio extension offering up to six audio output channels. Initially, AC3 was used for the audio format. Yet, today, you can rely on it for various applications, including Blueray, HDTV, game consoles, and DVDs. Multiple applications can open the AC3 audio files, from Apple Quicktime and Microsoft Windows Media Player to Winamp and MPlayer. AC3 files have a binary structure based on the MDCT compression algorithm. In addition, this file became the standard of Dolby Digital in 1991. It compresses multichannel audio files without affecting the sound quality. The compressed files are small-sized, making them easy to distribute.
