Re: [LAU] ladspa - noise removal

2008/5/4, cdr <_(a)whats-your.name>me>: you mean sum stereo channels -> mono ? because the noise of each channel is somehow inverted / phase shiftet? how to do that ? yes, I think, that's what I want in this case. I just tried "Hard Gate" ladspa. At high values it hacks the sound, creating even more noise. At low values it hacks start/end of the sound but removes what I call silence-noise. So a "Soft Gate" with same fade-in/out might be suitable. Couldn't find any in the ladspas on my system. Is it called differently? jey..just found out, that rezound has a such a gate in the remaster menu. I got acceptable results with a threshold of about -64 dBFS with audio normalized at about -0.82 dBFS I also gave audacity a try. I like the way the noise removal works there, though I don't know how it changes/effects the sound... I would use audacity, if it only was stable with a working jack driver.. annotation: It would be usefull, if the ladspas provided a "build-in" documentation, two/three sentences, that way giving non-engeniers a better idea, what they'd be doing. will that come with lv2 ? Another noise problem: Sometimes my mic-level shows a meter flickering in the lower range, that doesn't seem to come from background sounds, thus creating unacceptable noise... At the moment it's gone, but it would be pretty usefull, to know where it's coming from and how to avoid it. electric / magnetic influences by other cables ? my setup: low priced dynamic mic plugged via xlr into external ua-25 edirol usb card (limiter on, phantom off). the card uses usb power from the notebook. neither notebook nor peripherials have any ground connection afaikt. thanks for your comments, suggestions
