This program converts sampling rates of PCM wav files. This program also has a function to apply dither to its output and extend perceived dynamic range.
Sampling rates of 44.1kHz and 48kHz are populary used, but the ratio between these two frequencies is 147:160, which are not small numbers. As a result, sampling rate conversion without degradation of sound quality requires filter with very large order, and it is difficult to have both quality and speed. This program quickly converts between these sampling frequencies without audible degradation.
