About formats

M2TS (MPEG-2 Transport Stream) is a container format used primarily for multiplexing audio, video, and other data on Blu-ray Disc media. The format is specified as part of the Blu-ray Disc Audio-Video (BDAV) standard developed by the Blu-ray Disc Association, with commercial Blu-ray products launching in 2006. M2TS files wrap content in MPEG-2 transport stream packets with an additional 4-byte timestamp header prepended to each 188-byte packet, resulting in 192-byte packets that enable more precise timing and error recovery during optical disc playback. This extended packet structure helps maintain synchronization when dealing with the variable read speeds inherent to disc-based media. M2TS supports the major Blu-ray video codecs including H.264/AVC, MPEG-2, and VC-1, alongside audio formats such as Dolby TrueHD, DTS-HD Master Audio, and LPCM for lossless surround sound. The container is also used by AVCHD camcorders for recording high-definition footage, making it common in both consumer disc playback and video production workflows. M2TS files preserve chapter markers, subtitle streams, and interactive menu data within the transport stream. Reliable synchronization mechanisms and support for high-quality codecs make M2TS well-suited for archiving high-definition content where preserving full source quality is essential.

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.

Frequently Asked Questions

Why convert M2TS to DVMS?

DVMS is used in voice messaging and telephony systems. It stores voice efficiently for telecommunications applications.

What opens DVMS files?

SOX audio toolkit and DVMS-compatible telephony systems can process and play DVMS audio files.

Is DVMS for speech only?

DVMS is optimized for voice-band signals. It is designed for speech, not music or general audio applications.

What quality does DVMS offer?

DVMS stores voice-grade audio. Quality is adequate for speech intelligibility but not suited for high-fidelity listening.

Can I batch-process to DVMS?

Upload several M2TS files and extract DVMS audio from each in one batch for efficient processing.
