About M2TS to AMR Conversion
M2TS files from Blu-ray discs and AVCHD cameras contain high-fidelity audio — often Dolby AC3 5.1 surround at 640 kbps or DTS at 1.5 Mbps. AMR (Adaptive Multi-Rate) is an ultra-compact narrowband speech codec operating at 4.75-12.2 kbps with an 8 kHz sample rate, designed for GSM cellular voice. Converting M2TS to AMR represents the most extreme audio compression possible — reducing multi-channel HD audio to a telephone-quality mono signal.
Why Convert M2TS to AMR?
AMR conversion from M2TS is relevant when you need to extract voice or dialogue content from Blu-ray or camcorder recordings for use in voice messaging, IVR systems, or devices that only support AMR. The resulting files are incredibly small — a one-hour audio extraction at 12.2 kbps is just 5.5 MB. This is useful in bandwidth-constrained environments, embedded systems with AMR-only decoders, and legacy mobile voice platforms.
Common Use Cases
- Extracting dialogue from Blu-ray M2TS for voice analysis or speech recognition research
- Creating voice message clips from AVCHD camcorder recordings of speeches or interviews
