How do I convert an AMR file to VMS?

Upload your .amr file, choose VMS as the output format, optionally set bitrate to 12.2 kbps, then click Convert. After processing, download the .vms file. No registration needed.

Why should I convert AMR to VMS?

AMR files are speech-optimized but often incompatible with legacy PBX and voicemail systems that require VMS containers. Converting ensures playback on older telephony equipment and provides a fixed bitrate for predictable storage.

What happens to audio quality during AMR to VMS conversion?

AMR's adaptive bitrate (4.75–12.2 kbps) is transcoded to VMS's fixed 12.2 kbps, resampling audio if sample rates differ. Mono/stereo channels are preserved when possible, but some metadata like timestamps may be lost in the VMS container.
