Why would I convert M4A to VMS?

M4A is a compressed AAC audio file used for music, while VMS is a low-bitrate voice format used by voicemail systems and PBX switches. Converting M4A to VMS makes the file compatible with legacy voicemail hardware and reduces file size significantly for long recordings.

How does M4A to VMS conversion affect audio quality?

Converting M4A (AAC) to VMS (GSM/ADPCM) requires re-encoding. The VMS codec typically uses 8-16 kbps sampling, which reduces the original bitrate and frequency bandwidth. This results in lower fidelity but preserves clear speech. Metadata such as album art is discarded during conversion.
