OGG is an open-source multimedia container developed by the Xiph.Org Foundation, most commonly holding Vorbis audio. It is the preferred audio format on Linux, is natively supported by Firefox and Chrome, and is used by Spotify for streaming. Converting AMR voice recordings to OGG Vorbis gives you an open, patent-free audio file with excellent compression efficiency.
OGG Vorbis offers better quality-per-bit than MP3 at equivalent bit rates, and it is completely free of patent licensing concerns. For open-source projects, Linux distributions, and web applications targeting Firefox or Chrome, OGG is the natural choice. The format is also used by many game engines (Unity, Unreal, Godot) for in-game audio, making it relevant for interactive media production.
FFmpeg decodes the AMR audio to PCM and re-encodes it using the libvorbis encoder at a quality setting of q3 (approximately 112 kbps VBR). The audio is wrapped in an OGG container with full Vorbis comment metadata support. Variable bit rate encoding allocates more bits to complex passages and fewer to silence.
Vorbis at quality 3 (~112 kbps VBR) is more than adequate for voice content. The codec was designed to outperform MP3 at equivalent bit rates, and for narrow-band speech from AMR sources, it produces clean, artifact-free output.
