ตัวแปลงไฟล์ออนไลน์ฟรี DVMS เป็น WAV

Used in Germany to compress speech audio for voice mail. A self-describing variant of cvsd (Continuously Variable Slope Delta modulation).

One of the most common audio formats. The format was developed by Microsoft (in collaboration with IBM) and usually stores uncompressed audio data with pulse-code modulation, but it can be used to store sound processed with other audio codecs.
