Aligning Audio Levels for Bulk CD-to-MP3 Conversion?

Posted by Cliff on Thursday March 30, 2000 @05:11AM from the lets-normalize-the-levels-people! dept.

cmaxx asks: "Has anyone got a tool or method for aligning the recording (playback) levels of their CD's when converting to mp3? It's winding me up that some CD's were recorded quietly (for dynamic range reasons perhaps) while other were recorded normally or loudly, or with too little bass/top-end/whatever. It means that playing my mp3 collection randomly means I'm forever having to change the volume or equaliser settings to get the most out of the music. I know it's not a straightforward problem, but I'm curious to know, in this age of napster, if someone's cracked it - and if I can too." Interesting thought. At the very least some form of database is necessary to store the audio levels for each song.

sox should be able to do renormalization in unixland. No need for fancy Winders Software.

cdripper | sox -normalization_flags | mp3encoder Voila!

No I'm not advocating Windows, but... by kcarnold · 2000-03-30 07:04 · Score: 3

There's a nice (and I do mean nice) plugin for WinAmp called RockSteady (you can grab it and a whole bunch of other plugins at WinAmp.com).

"Saves you from the varying volumes of your MP3 collection" (or something like that)

I can't help you for Unix. (but did you notice how familiar that DOS shell script was in another comment? Bourne shell code below all that? Without the source, you'll never know...)
