I need some help from a sox guru. I have one directory with 260 sound files encoded as Mono 44100 16 bit PCM wav files and a second directory with 400+ wav files that are a mix of Mono and stereo. I need to batch convert them to mono 8000 u-law files. I've spent several evenings experimenting with sox with zero luck. I can play a file I've converted to mono 8k ulaw (with audacity) with this command... sox --no-clobber -D -G -S -c 1 -r 8k -t ul (filepath\filename) -d The working environment is 32 bit Win7 ... Thanks in advance... Mike ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
