Why convert OGG to Opus?
Opus, Vorbis's successor from the same open-source community, gives better quality at low bitrates.
What happens when you convert OGG to Opus?
Fylo re-encodes Vorbis to Opus at 48 kHz, 160 kbps by default.
How does Fylo convert OGG to Opus?
Fylo decodes the Vorbis audio in the OGG with ffmpeg compiled to WebAssembly and encodes it with FFmpeg's native Opus encoder at 160 kbps and 48 kHz in an Ogg container. Both formats are lossy, so each conversion discards a little detail — start from the highest-bitrate OGG you have. A 3-minute song is ≈ 3.6 MB at 160 kbps as OGG and ≈ 2.9 MB at 128 kbps as Opus. Opus always runs at 48 kHz, so the audio is resampled if needed.
What's the difference between OGG and Opus?
Ogg is an open container from the Xiph.Org Foundation; Vorbis, the audio codec most .ogg files use, reached version 1.0 in 2002. Vorbis was created as a free, unpatented alternative to MP3 and sounds better at the same bitrate.
Opus is an open, royalty-free codec standardised by the IETF as RFC 6716 in 2012. It blends speech technology from Skype's SILK with music coding from Xiph's CELT, so it handles both voice and music well. Files are usually stored in the Ogg container with the .opus extension.
