DVMS is a proprietary audio format developed by Microsoft for use with its Digital Video Recording System (DVRS).
The DVMS audio format is typically used in conjunction with video recordings made by the DVRS. The audio data is stored in a separate file from the video data and is encoded using Microsoft's proprietary audio codec. The format is designed to provide high-quality audio with a low data rate, making it ideal for use in digital video recording applications.
However, it is worth noting that the DVMS format is not widely used outside of the DVRS system, and is not supported by many third-party software applications. If you need to work with DVMS audio files, you may need to use specialized software or seek out support from Microsoft or the manufacturer of the DVRS system.
