I've been looking for a while for a DC Offset corrector Plugin
Even some "Professional" Recorded CD's have DC Offset errors.
0.1 Percent DC Offset mismatch, or more, so i need to correct this.
Wavelab has an Option and i saw some Solution from DMXMON, but it is just a DirectX Audio Plugin
Hope a Lame'r can implement DC Offset correction as a - option.

Hmmm... have no idea how easy or difficult it would be to do this.

A method I've seen, in Cool Edit (and probably many other good Audio Editors) there is a feature to fix this.

But, it's a bit of a pain to have to record tracks out as wav's, fix, and reburn/encode...

Maybe Peter will whip up a plugin between courses at his Thanksgiving dinner.. ;-)

Just out of curiosity, what kinds of problems does excessive DC offset cause? I've heard that filtering and
denoising algorithims work better on offset free files...

every version of sound forge I've seen has DC offset functionality as a standard feature. You can specify the amount of correction you'd like to apply, or have it analyze and correct on its own. When you let it do it on its own you can choose from only analyzing the first 5 seconds of the file or the whole file. And of course you could simply select a region on your own, hit statistics, and take the DC offset value from there and use it manually

Why would you want to correct the DC offset of a CD? Unless you happen to have a 20-bit copy of the CD, you're only making it sound worse because of requantization noise. Besides, DC offset doesn't affect what you hear, unless it causes the signal to clip (and if this happens, using a DC corrector won't fix it). I suppose if you had a crappy DAC, which clips before reaching 0dB, then performing DC correction would make some sense (but that would mean that you should really buy a new soundcard). If you really want DC correction, I'd suggest doing it on playback, not to a file - http://www.dspguru.com/comp.dsp/tricks/alg...lg/dc_block.htm has an algorithm for DC blocking for those who are interested.
