    About AC3

    AC3 is a Dolby Digital audio format made for movies and surround sound. Use it when you want big, theater-like sound at home or when a player or TV specifically needs Dolby Digital.

    • Ideal for surround sound in home theaters, keeping dialogue clear and effects powerful.
    • Works on many AV receivers, TVs, soundbars, and DVD/Blu‑ray players, but support in web browsers and some phones is limited.
    • Offers good movie sound while keeping file size smaller than uncompressed audio.
    • A smart choice when converting a movie or TV show to keep its surround sound track.
    • Not great for web use or everyday music players—choose AAC or MP3 if you need broad compatibility.
