- Description
- The WTV (Windows Recorded TV Show) file format is used by Microsoft's Windows Media Center to store TV recordings. Introduced with Windows 7 as a successor to the earlier DVR-MS format used by Windows XP Media Center Edition, WTV files allow users to record live television broadcasts or schedule recordings directly through their computers equipped with a compatible TV tuner card. These files encapsulate both the video and audio streams, along with metadata such as broadcast information and closed captions.
- Waveform audio file created in the NIST SPHERE format, which is often used in speech recognition research; often contains a recording of a person speaking; can be provided as input to speech recognition systems.
