Subject: Re: increasing / normalizing loudness for large numbers of wav From: Catherine Warrier <cwarrier(at)northwestern.edu> Date: Thu, 29 Jul 2004 10:02:40 -0500Dear List, Here's another program for adjusting the level of multiple wav files. "Level" was written by Tom Carrell and Bob Tice, and is freely available on their Speech Lab Resources website, http://hush.unl.edu/LabResources.html It lets you set the level of sound files to either a specified dB level or to the level of a particular file, which can come in handy. You can also change the level of all files by a certain dB amount. Here's a description taken from the program instructions: "Level is used to measure and/or change the dB RMS level of stimulus files listed in an SSF (Stimulus Set File). It can also process single files, if desired. Level can operate on either ADF or WAV files." I don't know the exact algorithm used, but people in the lab here have used it successfully. All the best, Catherine Warrier ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- Catherine Warrier, PhD Research Assistant Professor, Knowles Fellow Auditory Neuroscience Laboratory Northwestern University ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-
