AMR (Adaptive Multi-Rate) is a speech-optimized audio codec used by mobile phones for voice recordings and MMS messages. It produces extremely small files — a 1-minute recording is about 50–100 KB. Converting Xvid to AMR extracts speech audio for mobile voice messaging, telephony systems, and devices with limited storage.
| Use Case | Quality | Channel | Sample Rate |
|---|---|---|---|
| Voice message | Constant Bitrate: 12.2 kbps | Mono | 8000 Hz |
| MMS audio | Quality Preset: High | Mono | 8000 Hz |
| Telephony | Constant Bitrate: 7.4 kbps | Mono | 8000 Hz |

Yes. Under "Trim," set a start time and duration.
