MTS/AVCHD camcorders capture audio as AC3 surround or LPCM stereo — high-quality sources that produce excellent results when extracted to Ogg Vorbis, the open-source lossy codec developed by Xiph.org. Ogg Vorbis provides quality competitive with AAC while being completely patent-free, making it the preferred audio format for open-source platforms, web applications, and game engines.
Extracting camcorder audio to Ogg Vorbis serves two primary audiences. Web developers need Ogg for HTML5 <audio> elements because it is natively supported in Firefox and Chromium without patent licensing — critical for sites serving audio at scale. Game developers use Ogg Vorbis as the standard audio format in Unity, Unreal Engine, and Godot because of its efficient streaming decoder and loop-friendly gapless playback.
For organizations with open-source mandates — government agencies, educational institutions, non-profits — Ogg Vorbis is the format of choice because it carries zero patent risk. Extracting camcorder audio to Ogg ensures these recordings can be used, distributed, and archived without licensing concerns.
FFmpeg strips video and encodes with libvorbis: `-vn -c:a libvorbis -q:a 6 -ar 48000 -ac 2`. For 5.1 AC3 sources, downmix: `-ac 2`. Vorbis quality levels range from -1 (~45 kbps) to 10 (~500 kbps), with q:a 6 producing approximately 192 kbps VBR. Vorbis always uses variable bitrate encoding — there is no true CBR mode.
Vorbis at quality 6 (~192 kbps) from AVCHD's high-quality audio source produces transparent results for most content. The format excels at low bitrates (80-128 kbps) where it outperforms MP3 in listening tests. Since the camcorder source is high quality (AC3 at 256+ kbps or LPCM), Ogg Vorbis at q6 preserves the vast majority of audible detail.
