Convert MP2 to AMR — Free Online Converter

Converting MP2 to AMR re-encodes broadcast-quality MPEG Audio Layer 2 into the Adaptive Multi-Rate speech codec designed for GSM telephony. This is a drastic quality reduction — broadcast MP2 at 256 kbps provides FM-radio-quality stereo, while AMR-NB at 12.2 kbps provides telephone-quality mono speech.

This conversion only makes sense for speech content from broadcasts that needs deployment on telephony systems. Music, ambient audio, and complex broadcast mixes are unsuitable for AMR encoding.

Broadcast speech content — news bulletins, talk radio segments, spoken announcements — may need to be delivered through telephony systems (IVR, voicemail, MMS) that require AMR format. Converting the MP2 broadcast audio to AMR enables deployment on these telecommunications platforms.

Some regions distribute radio news and emergency broadcasts through cellular networks using AMR format. Converting the original MP2 broadcast to AMR enables this secondary distribution channel.
