What is a CVSD file?
A CVSD file is an audio file encoded using Continuously Variable Slope Delta Modulation. It likely contains audio transmitted over a radio or telephone. CVSD files are uncommon, so most popular audio players cannot open them.
CVSD encoding was developed in the 1970s. It is used primarily to encode audio signals sent via radio, telephone, and other voice communication methods. For example, some Motorola radios encode audio using CVSD, as do some digital telephones.
How to open a CVSD file
You can use liquid-dsp (multiplatform) to process and manipulate the audio a CVSD file contains.
