Hi, Thanks for sharing your work. I installed and used it to evaluate the speech quality.
I used example speech_A (16kHz) as both ref and deg, and the PESQ score (wb mode) was 4.644.
i down-sampled speech_A to 8kHz speech_B, and ref=speech_A and deg=speech_B. When i call pesq(rate_A, ref, deg, 'nb') and pesq(rate_B, ref, deg, 'nb'), i got different results.
I got 2 questions: 1. What is the range of the PESQ scores calculated with your package? 2. Why got different results using rate_A and rate_B for the above calls?
Please let me know the correct method to call the function.

Thanks,
Willy
