I use a guide you gave me, about making a stereo signal into a 5.1 ac3 signal. In that guide he uses 44.1 khz sound. Can i use 48 khz instead? The 3 wav files that are included in the guide (UHJ_W_4416.wav, UHJ_X_4416.wav and UHJ_Y_4416.wav) are saved with 44.1.... i need to encode the final ac3 in 48.. I've tried to resample the file that the guide produces to 48, but when i open it in soft encode it opens it as an mono signal, not an 5.1 /Anders
