What is an .AC3 file?

AC3 files are audio files saved in the Audio Codec 3 (AC-3) format. Dolby Laboratories developed the format for multi-channel sound encoding, and it utilizes lossy compression to reduce file size while maintaining high-quality audio, making it a good option for home theater systems, DVDs, Blu-ray Discs, and digital TV broadcasts. AC3 files typically support up to six discrete audio channels, including 5.1 surround sound.

You may encounter AC3 files as standalone audio tracks or embedded within video files that use Dolby Digital audio. They are commonly used in professional video production and media distribution to deliver cinema-quality sound at manageable bitrates. File Viewer Plus can play your AC3 files and convert the audio to MP3 and M4A formats at different bitrates and sample rates.
