I compared the sample Beautyslept at radio profile, and the consequences of the PNS tool (mpc 1.14). I couldn't differenciate the two encodings.1R = C:\Temp\Pns\Sample03\BeautySlept_Q4xlev.wav 2R = C:\Temp\Pns\Sample03\BeautySlept_Q4xlevNOpns.wav ABX Results: Original vs C:\Temp\Pns\Sample03\BeautySlept_Q4xlev.wav 8 out of 8, pval = 0.004 Original vs C:\Temp\Pns\Sample03\BeautySlept_Q4xlevNOpns.wav 8 out of 8, pval = 0.004 C:\Temp\Pns\Sample03\BeautySlept_Q4xlev.wav vs C:\Temp\Pns\Sample03\BeautySlept_Q4xlevNOpns.wav 5 out of 12, pval = 0.806 [CODE] Tried with Bachpischord : [CODE] 1R File: C:\Temp\Pns\Sample03\Bachpsichord_Q4xlev.wav 1R Rating: 2.0 1R Comment: very grainy --------------------------------------- 2L File: C:\Temp\Pns\Sample03\Bachpsichord_Q4xlevNOpns.wav 2L Rating: 3.0 2L Comment: --------------------------------------- ABX Results: C:\Temp\Pns\Sample03\Bachpsichord_Q4xlev.wav vs C:\Temp\Pns\Sample03\Bachpsichord_Q4xlevNOpns.wav 14 out of 20, pval = 0.058 PNS encodings is worst in this case : sound is grainy, and more unpleasant. I didn't noticed it with BeautySlept. But I must say that I had some difficulties to hear difference between original and -radio (notation : 4.4 and 4.6 ), less pronounced to my ears than with Bachpsichord (2 and 3/5).
