Hi SoX users, This command works for me: 1) sox --channels 1 --rate 48000 in_signal.wav in_signal.s32 Now, I'd like to change the output filename extension. In that case SoX can't deduce the format from the extension, so I have to tell it the details. I tried the following line: 2) sox --bits 32 --channels 1 --encoding signed-integer --rate 48000 in_signal.wav --type raw in_signal.q31 However, I am not getting the same output as using the first command. What's done wrong in the second command? Cheers, Danijel Domazet -- - Confidential -
