I've done two filters in cascade with Sox. Here is the Batch, you just have to drop wav file in it :
cd %~dp0 mkdir "converted e 32 LowPass-fichierAudio rate -V -p 15 -b 85 -a 88200" FOR %%A IN (%*) DO sox %%A -e float -b 32 "converted e 32 LowPass-fichierAudio rate -V -p 15 -b 85 -a 88200/%%~nxA" lowpass -2 18000 rate -v -p 15 -b 85 -a 88200 It is resampling intermadiate phase 15, band limited to 85%, allow Aliasing, all this to have as limited pre and post echoes as possible plus a second order butterworth lowpass filter centered at 18k the low pass allows shortening post echoes Best Regards, Jean -- bidule ------------------------------------------------------------------------ bidule's Profile: http://forums.slimdevices.com/member.php?userid=15337 View this thread: http://forums.slimdevices.com/showthread.php?t=69145 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
