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.

PVF (Portable Voice Format) is a simple audio file format designed for voice message storage in Linux-based telephony systems, most notably ISDN4Linux and its vbox voicemail application. The format emerged from the European ISDN ecosystem of the late 1990s, when Linux servers increasingly handled PBX and answering machine duties over digital phone lines. PVF files store raw signed 16-bit PCM samples at 8000 Hz mono, preceded by a minimal plain-text header specifying data format and byte ordering. This deliberate simplicity is one of the format's primary strengths — with no compression and a human-readable header, PVF files are trivially easy to parse, pipe, and manipulate using standard Unix tools. The 8 kHz rate matches the Nyquist requirement for telephone-bandwidth speech (300-3400 Hz), making PVF a natural intermediate format for voice processing pipelines. Another advantage is cross-architecture portability: the explicit byte-order declaration means PVF files move between big-endian and little-endian systems without ambiguity. The SoX audio toolkit provides native PVF read/write support, enabling straightforward conversion to modern formats.

Frequently Asked Questions

Why convert M2TS to PVF?

PVF (Portable Voice Format) is used in telephony and voice systems. It stores voice data in a simple, portable container.

What opens PVF files?

SOX audio toolkit, Audacity, and telephony software can read and process PVF files for voice-related applications.

Is PVF for speech only?

PVF is optimized for voice recordings. General music will lose fidelity — use other formats for music extraction from M2TS.

How small are PVF files?

PVF files are compact, focused on voice-band frequencies. They are efficient for telephony and voice data storage.

Can I batch-convert to PVF?

Upload multiple M2TS files and extract PVF audio from each simultaneously for efficient batch processing.
