Note: libresample and sndfile-resample (from libsamplerate) are already included in the Planet CCRMA Distribution. If you are running Red Hat Linux, check out the Planet. There is also SoX (which uses libsoxr, the SoX resampler library) to change sampling rates by this method. Say port search sox (Mac), yum search sox (Linux), etc., to find it. See also ssrc (from Shibatch) which is a fixed-point

Moore and Glasberg [19] have revised Zwicker's loudness model to better explain (1) how equal-loudness contours change as a function of level, (2) why loudness remains constant as the bandwidth of a fixed-intensity sound increases up to the critical bandwidth, and (3) the loudness of partially masked sounds. The modification that is relevant here is the replacement of the Bark scale by the equival
