Hi, didn't find an answer in the mailing list archives nor the web. I am trying to normalize multiple files while keeping their relative levels intact. Is there a way to do this with SoX in one call? How could it be done with multiple calls (eg. analyze first, then raise gain of all files)? thanks for ideas!
