Supports: MPG, MPEG
Converting MPEG to AMR extracts the audio track from a video and encodes it in the AMR (Adaptive Multi-Rate) format — a speech-optimized codec used by mobile phones. AMR produces extremely small files (a 1-minute recording is ~50–100 KB) by aggressively compressing audio to speech-quality levels.
This is useful for extracting dialogue from video recordings for telephony systems, creating ultra-small audio files for mobile messaging on bandwidth-limited networks, or preparing audio for legacy mobile applications that only accept AMR input.
| Feature | MPEG (source) | AMR (output) |
|---|---|---|
| Contains video | ✅ Yes | ❌ No (audio only) |
| Audio quality | CD-quality possible | Speech quality (8 kHz) |
| File size (1 min) | 10–50 MB | 50–100 KB |
| Best for | Video playback | Voice/speech only |
| Music quality | ✅ Good | ❌ Poor (speech codec) |
No. AMR is designed exclusively for speech at 8 kHz sample rate. Music will sound heavily distorted. For music extraction, convert to MP3 or M4A instead.
AMR is used in telephony, IVR systems, and mobile networks where bandwidth is extremely limited. It's also the native voice memo format on some older phones.
Yes. Upload multiple files and they will all be converted to AMR. Download individually or as a ZIP archive.
Yes. The video track is discarded and only the audio is extracted and re-encoded as AMR.
