here are two other trials 1° Minimum phase upsampling + lowpass
cd %~dp0 mkdir "converted e 32 LowPass-MINIMUMfichierAudio rate -V -M -b 85 -a 88200" FOR %%A IN (%*) DO sox %%A -e float -b 32 "converted e 32 LowPass-MINIMUMfichierAudio rate -V -M -b 85 -a 88200/%%~nxA" lowpass -2 18000 rate -v -M -b 85 -a 88200 2° Minimum phase upsampling + Bandpass (longuer post ripple, but possibly better phase and frequency attenuation) cd %~dp0 mkdir "converted e 32 SINCPass-fichierAudio rate -V -M -b 85 -a 88200" FOR %%A IN (%*) DO sox %%A -e float -b 32 "converted e 32 SINCPass-fichierAudio rate -V -M -b 85 -a 88200/%%~nxA" rate -v -M -a -b 85 88200 sinc -M -t 1 44000-22000 Your input in terms of sound preference and therory would be appreciated.
