    Rms equalization in Audition

    hearlab

      We would like to normalize some *.wav file to a specific average rms level.  What set of functions/steps best accomplishes this?  The normalize function does not seem to be based on rms of the file.   Any input would be appreciated.  Thanks!

          Use 'Group Waveform Normalize' on the edit menu in Edit mode (which also works for single files) and uncheck the option for 'Use Equal Loudness Contour'. This will give you accurate RMS with no weighting. I think the Normalize option on the Effects|Amplitude menu is A-weighted (see http://en.wikipedia.org/wiki/A-weighting).

            Actually it isn't - it's just analysed to a normal loudness contour, and they aren't quite the same as A-weghted ones, although the 40-phon one is supposedly what the A curve is based on. Adobe haven't actually specified which contour though, so all bets are off, really.

              I have trouble finding an answer to this. In Sound Forge, I can apply an average RMS normalisation to say, -15dB, and when I measure it, it's -15dB. I cannot find how to do this among the tools in Adobe. The "Total RMS Amplitude" level in Amplitude Statistics seems to correspond to this, but how do I adjust an audio file to this setting?

              Speech Volume Leveler* seems to be the closest I can get, but I don't know exactly what "Target Volume Level" (RMS) refers to. It isn't "Total RMS Amplitude" as in Amplitude Statistics.

               

              (* Never mind the fact that "Speech" is a human interpretation of what an audio signal represents & is the kind of effect description more common in less technical, general public freeware).

                Try opening the Match Volume panel from the Window menu and dragging your files there.

                  Try this:

                   

                  Convert file to format mp3 in Adobe Audition. Next open Winamp, load converted file into this program and send this file into Calculate ReplyGain. Write down information Track Gain for this file from Replay Gain Result. Return to Audition.Open this original file again in Audition (non mp3). Use Effects-> Amplitude and Compression -> Amplify/Fade (process) in version 3 or Amplify (if you use higher version).

                   

                  In version 3:

                  Set View all Settings in dB and Lock Left/Right

                  In section Amplification write down information Track Gain for this file from Replay Gain Result from Winamp Calculate ReplyGain.

                  Hit OK.

                   

                  In higher version:

                  Check Link Sliders. Tick must be on.

                  In section Gain write down information Track Gain for this file from Replay Gain Result from Winamp Calculate ReplyGain.

                  Hit OK.

                    This is a very old thread. The OP was in 2010 and the last answer from Durin three years ago. Audition has progressed considerably since then. The latest versions support all form of volume normalisation including the latest international specced R128, BS 1770 as well as standard loudness settings for RMS levels. These are now all under Match Loudness in the Effects menu.
