Software for Normalizing Multiple WAV Files

[wwaag]

What software does anyone use or recommend for normalizing the volume of multiple WAV files? These are for "home videos" to be put on DVD. Some are voice files, others music. Since they were recorded differently, how can they be normalized to avoid having to constantly adjust the volume when played back? Thanks in advance.

Use wavgain:http://www.answermonkey.net/App_WAVGain.htm
But if you have one long wav and you would like to edit and cut into smaller files I recommend converting to mp3 using CDex and "normalizing" with MP3Gain.

MP3Splitter is another great tool:

Thanks for the info. Worked great. Converted WAVs using CDex to MP3, then MP3Gain to normalize, and CDex to convert back to WAVs. Too bad that MP3Gain doesn't work directly with WAV files. Thanks again.

Sonic Foundry has a Batch Converter. I'm pretty sure they have a demo for it, but if its like any of their other demos it will probably add beeps every few seconds. With the Batch Converter you can import all the .wav files you want and choose any processes and/or effects and apply them to all the files. Hope that helped.

normalize is a command-line tool (it's a Windows build of a UNIX program), but it will work directly on WAV files (and also MP3 files). It's pretty versatile and easy to use, and I've had good results using it on WAV files for mix CDs. I don't know if there's a nice pointy-clicky Windows front end for it anywhere, but you really shouldn't need one.
