無料オンラインVMSからMP3へのコンバーター

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

Is the most common format for storing audio. Almost any player on any platform can open mp3 files. The audio is compressed with loss of quality, but the loss is negligible for the typical user, and the file size is usually less than that of the original files.
