RMS measure

[oelewapper]

Does anyone know of a DOS based program to measure the average RMS of a WAV ?

TIA !!

A DOS based?

If you want a command line tool you can use wavrms from Aften package (http://forum.doom9.org/showthread.php?p=996683#post996683):
>wavrms

WavRMS: utility program to calculate AC-3 dialnorm.
(c) 2006-2007 Justin Ruggles, et al.

usage: wavrms <test.wav> [<start> [<end>]]
use '-' to input from stdin.
unit for start and end is seconds.

It doesn't do mono wavs.............

So to rephrase my question :

Does anyone know of a DOS based program to measure the average RMS of a MONO WAV ?

The LAME command line reports a replaygain figure - this is not the same as RMS value but it's another measure of the "average" sound level so it might be useful to you.

I don't know if there's a switch to scan the wav and report the replaygain and not actually encode an MP3!

Oh and I think you need to add -20dB to the figure it gives (i.e. a replaygain of 0dB means the average level of the file is around -20dB).

One point I noticed in this thread:
WavRMS: utility program to calculate AC-3 dialnorm.AC3 dialnorm is based on LAeq (of normal dialogue) which, like replaygain, is not the same as RMS. So really it should be described as "program to estimate AC-3 dialnorm."

Thanks, but not useful for what I'm working at.......

There must be something real simple somewhere......

You could try Normalize utility (http://normalize.nongnu.org/) with which I consistently achieve good results on my WAV files.
I'd suggest to run it like this:normalize.exe --amplitude=-20.0dbFS --no-adjust yourfile.wav"
and you will see the actual RMS level. Works for mono wavs as well.

Thanks !! This is what I was looking for.....
