About formats

WTV (Windows Recorded TV Show) is a digital video recording format developed by Microsoft and introduced in July 2008 with the Windows Media Center TV Pack for Windows Vista. The format was designed to replace the earlier DVR-MS recording format used by Windows Media Center, offering a more capable container for recording live television broadcasts. WTV files store video in MPEG-2 or H.264 encoding alongside multiple audio tracks in AC-3 or MPEG audio format, along with closed caption data, electronic program guide metadata, and copy protection flags. The container uses an internal directory structure that supports time-shifting features, allowing Windows Media Center to record content while simultaneously enabling playback from the beginning of the recording. A rich metadata framework preserves detailed program information from the electronic program guide (EPG), including show title, episode description, genre, ratings, and original air date, making it easy to organize and browse recorded content. The format supports both standard definition and high definition recordings from digital cable, over-the-air ATSC, and ClearQAM tuner sources. WTV files are natively accessible through Windows Media Center and can be converted to the simpler DVR-MS format using built-in Windows tools. While Windows Media Center was discontinued after Windows 7 (with limited support in Windows 8), WTV files remain in personal media archives and can be processed by third-party video tools.

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 WTV to PVF?

Extracting audio from a WTV recording into PVF lets you save the soundtrack of a TV show for offline listening on any device.

How can I play PVF files?

Specialized telephony and voice processing tools can work with Portable Voice Format files.

How fast is the audio extraction?

Audio extraction is quicker than full video conversion since only the sound track is processed. Most files are done within seconds.

Can I choose the audio bitrate?

Yes. Adjust the bitrate, sample rate, and channel count before converting to get the PVF quality that suits your listening needs.

Is registration necessary?

No. Basic conversions work without an account. Signing up is optional and provides access to extended features and larger uploads.

Will the audio quality match the original?

You can set the output bitrate to match or exceed the original audio quality. Higher settings preserve more detail from the WTV source.
