is it from a sample or a Vst that creates it? if its from a sample(already created waveform) then you have to use the tool vegetal suggest, i will get it as well..

cheers vegetal

if its from a vst i think you can highpass from 20hz and its gone... in realtime of course

here is a great informative page about it all

and here is the wiki

Highpass will work on anything that has DC, whether it's a sample or VST. I recommend Waves Q6 or Q8 with every band set to the same frequency.

No, DC stands for Direct Current, and can be thought of as a signal with a frequency of 0Hz. In an audio file it looks like a constant offset from the zero line (ie. it shifts the entire waveform up or down by a fixed - or very slowly varying - amount), and it's not very good for speakers.

THx Colin, so it better pass every singel track into dC detector and remove ?
I've tried various audiofiles in a project(with logic's built in one) end always "No DC Offset Found"

no dc is not a big deal you don t have to care about this(except if it don t sound good offcourse but personaly i never check my sounds if they have dc or not),the only issu i know its you can juts loose a bit of headroom at mastering that why some limiters have a built in highpass filter to remove dc( for transparency a highpass filter as low as possible and the less steep can be used)

This is pretty much what I do, except my DC detector is a spectrum analyser - DC shows up as the far-left point on the curve. Most samples and VSTis don't contain or add it but some do, and some processes add very low frequencies which it's worth removing. You can't hear DC directly, but it can add a form of distortion to other sounds, and can potentially damage speakers. Analog sources are particularly prone to it but if you HP as a matter of course it will never be problem.

hay Colin this is really interesting, I also see that in Cubase u have an off-line process that called "remove DC offset" is this effective? is this an hi pass filter too?
