Its design and implementation is modeled after the CVSD encoder/decoder specifications defined in the Bluetooth standard. CVSD is a method for encoding speech that seeks to reduce the bandwidth required for digital voice transmission. CVSD takes advantage of strong correlation between samples, quantizing the difference in amplitude between two consecutive samples. This difference requires fewer quantizat..." current

It converts an incoming CVSD-encoded short to a float, decodes it to a float, decimates it, and scales it (by 32000; slightly below the maximum value to avoid clipping). The sampling rate can be anything, though, of course, the higher the sampling rate and the higher the interpolation rate are, the better the sound quality. When u..."
