About AMR
AMR (Adaptive Multi-Rate) is a speech codec designed for mobile networks; its narrow-band form codes voice at 4.75 to 12.2 kbit/s.
Voice notes and call recordings from older phones and dictation apps.
AMR keeps only the frequency range of speech, so music in an AMR file sounds poor, and converting it cannot bring the missing range back.
Convert AMR to Ogg Vorbis online free, no account required — Ogg Vorbis is an open, royalty-free lossy audio format.
Change AMR to Ogg Vorbis without losing quality — convert AMR to Ogg Vorbis free in your browser.
Why do my recorded calls sound so tinny and robotic? AMR was designed to squeeze narrow-band speech over 2G networks, so it discards almost everything but the voice — no conversion can restore the missing range.
About Ogg Vorbis
Ogg Vorbis is the open, royalty-free Vorbis audio codec in the Ogg container, developed by the Xiph.Org Foundation.
Games, open-source software and music streaming; Spotify has streamed its music in Ogg Vorbis.
Apple devices have limited support for Ogg Vorbis, and many car stereos do not play it.
Why convert audio to OGG? For open-source projects and game engines: the format is patent-free and browsers and engines play it natively.
What changes when you convert AMR to Ogg Vorbis
- The audio is decoded and re-encoded as Ogg Vorbis at the default settings, so the result is close to the AMR but not bit-identical.
- AMR and Ogg Vorbis are both lossy formats, so this conversion adds a second round of lossy compression; keep the original AMR if you may need the best quality later.
