Hello Vivek, I'm not familiar with PAQM, but it might be that PAQM uses the same transfer function of outer and middle ear as PEAQ (ITU-R BS.1387) does, because PAQM was one of the systems "integrated" in the PEAQ recommendation. PEAQ's function is derived from Terhardt: Calculating virtual pitch, Hearing Research Vol.1, 1979 You can find information about PEAQ's transfer function and PEAQ itself at: Best regards, Alexander > Vivek Srivastava wrote: > > Hello List, > I am a Masters student at Virginia Tech and am trying to > implement PAQM(a method to determine the audio quality of a > signal).
