Hi all, I want to make 3 changes to a wav-file: 1. bit depth, 2. upsampling and 3. sinc-filter - at one time. For the upsampling I assume -L and for the filter I assume -L. Does Sox calculate this several times in a row? Is this the correct and most effective command? sox 16bit_44_1.wav -b 32 -e float output.wav rate -v -L 88200 sinc -a 80 -L -21000 -t 2100 Regards Thomas _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
