bidule sorry for late response. Which one is first, second and third? This one you think is the best? (it is confusing me as you marked it in your response as #1, but refer to second..) 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 btw, why 88.2KHZ and not 96KHz? -- michael123 ------------------------------------------------------------------------ michael123's Profile: http://forums.slimdevices.com/member.php?userid=23745 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
