Batch amplifying WA vs. . by average RMS output

anonymous 12 August 2004

I'm working on a video game at the moment with 1500+ WAV files which represent all the bits of speech in our game. The problem is that they're not all consistent in average RMS output, varying anywhere from 3-9dB depending on which recording session they came from.

Ideally, I'd love to find a way to batch process them all so that their average RMS output is consistent, as it's my understanding that this is the best measure of "perceived loudness".

Anyone know a way? I've thought about using Cool Edit Pro to set up a batch script, but as far as I know you can only do this for peaks (normalising), not average RMS output.

I'm on Windows XP, btw.

Cheers. :)

I think WaveLab has a batch normalize that works with RMS settin

I think WaveLab has a batch normalize that works with RMS settings...

I would say that that's what mastering is for, but 1500 files...

I would say that that's what mastering is for, but 1500 files.... I'd be looking for a batch process too. Good luck.

Peak on the mac has a batch processor for files... maybe you ca

Peak on the mac has a batch processor for files... maybe you can find someone to run them for you-

wavelabs has a batch process. you just throw on the meta normali

wavelabs has a batch process. you just throw on the meta normalizer with RMS levels.

Then you can batch master them with your preset mastering setup. Not ideal, but timely.

I ended up using Adobe Audition 1.5 to do it, there's a great ba

I ended up using Adobe Audition 1.5 to do it, there's a great batch WAV normalisation tool in there. And for those interested it's up to 3000+ assets now... (shakes head in despair)

3000+ !!!??? Geez... For future reference, I'm pretty sure Soun

3000+ !!!??? Geez...

For future reference, I'm pretty sure SoundForge will do that also (although I never liked the way its Normalize function sounded...).
