M2TS vs AMR:
Name M2TS AMR
Full name BDAV MPEG-2 transport stream Adaptive Multi-Rate
File extension .ts .mts .m2t .m2ts .amr, .3ga
MIME video/MP2T audio/amr
Developed by Blu-ray Disc Association 3GPP
Type of format Media container Audio compression format
Introduction M2TS is a filename extension used for the Blu-ray Disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This container format is commonly used for high definition video on Blu-ray Disc and AVCHD. The Adaptive Multi-Rate (AMR or AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1999 and is now widely used in GSM and UMTS.
Technical details The BDAV container format is a modification of MPEG-2 transport stream (ITU-T H.222.0 | ISO/IEC 13818-1) specification for random-access media, such as Blu-ray Disc, DVD, hard drives or solid-state memory cards. It is informally called M2TS. AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband (200-3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s. Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200-3400 Hz.
