A fast and high quality sampling rate converter SSRC
SSRC converts sampling rate of PCM wav file. Also, this program 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 ratio of these two frequency is 147:160, and it's not a small numbers. Therefore, sampling rate conversion without degradation of sound quality requires filter with very large order, and it's difficult to achive both quality and speed. This program achived relatively fast and high quality with two different kinds of filters combined skillfully.
