FLV audio tracks are typically MP3 at 128-320 kbps or AAC-LC. OGG (Ogg Vorbis) is the Xiph.org Foundation's open-source lossy audio codec, released in 2000 as a patent-free alternative to MP3. Vorbis uses modified discrete cosine transform (MDCT) with floor/residue coding, achieving superior quality to MP3 at equivalent bitrates — particularly at lower bitrates below 128 kbps. Spotify uses Ogg Vorbis for its streaming format. Converting FLV to OGG produces patent-free, high-quality audio.
OGG Vorbis is completely open-source and royalty-free, making it the audio format of choice for open-source projects, games, and platforms like Spotify. It outperforms MP3 in blind listening tests at 128 kbps and below. If you need audio from FLV files for use in open-source software, game engines like Unity and Godot, or Linux distributions, OGG is the natural choice.
FFmpeg decodes the FLV audio stream to PCM and re-encodes using libvorbis. Vorbis supports VBR encoding with quality levels from -1 (roughly 45 kbps) to 10 (roughly 500 kbps). The default quality 5 produces approximately 160 kbps with excellent transparency. The output is wrapped in an Ogg container with Vorbis comment metadata. Sample rates up to 192 kHz and up to 255 discrete channels are supported.
Vorbis at quality 5 (~160 kbps) is perceptually transparent for most listeners — indistinguishable from the original in blind tests. At quality 3 (~112 kbps), it still outperforms MP3 at 128 kbps. The codec handles transients and complex stereo content particularly well compared to MP3. Quality loss from transcoding FLV's MP3 audio to Vorbis is minimal at adequate bitrates.
