What is a .CVSD file?
A .CVSD file is a type of audio file that uses a special method called Continuously Variable Slope Delta Modulation (CVSD) to encode sound. This method is often used for audio that is transmitted over radios or telephones. The audio in a CVSD file might include voices or other sounds that are sent through these communication devices.
Because the CVSD format is not very common, you might find that many of the usual audio players on computers and other devices cannot open this type of file. However, there is a specific program called liquid-dsp that can open and play CVSD files. Liquid-dsp is designed to handle various digital signal processing tasks, including working with uncommon audio formats like CVSD. If you have a .CVSD file that you need to listen to, you should use the liquid-dsp program to open and play the file.
