Yes, I understand that gain is gain, but he has to decide how much gain to apply. If he's previously done that in terms of a pre-gain peak level, but now wants to bring RMS levels to a certain point, he surely has to find out what the file's RMS levels are first then decide how much to modify it by? -- Jeremy Nicoll - my opinions are my own ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Sox-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sox-users
