I don't have an Cinevia to test it with .
I thought I had sen the sox in something I downloaded.
It was in the Hybrid suggested by Kerry in the free tool thread.
I have the portable.
Also was in another conversion software:
mediAvatar HD Video Converter
I also downloaded the sox portable from the link in the post above.
Played with it a little.
If anyone tries the sox portable from command try this at the command prompt.
sox input.wav output.wav reverse
You need to have the input.wav in the sox folder & it may not like tha actual name of the file. So if needed just rename it to input.wav.
