Did you ever get around to doing this as a plugin? :) Two years passed, I barely touched audio editing in that time, but today I used noisered for the first time. I have a recording made with excessively low levels (around -30dB Pk, -57dB RMS); yikes. So far, I've only found some quiet 100ms sections to make a noise profile with (due to people moving/talking around me). At first, the result was littered with nasty artifacts with the default noisered "amount" parameter (0.5). However, I found the results are pretty good with an "amount" value set to zero. Using a >0 amount seems to introduce unpleasant artifacts. I'll try to get a cleaner "silent" sample to noise profile with (recording a new silent track may be necessary). Most of the noise I'm trying to reduce is from my recording gear and mics. The blessing in that is it ought to be easy to make a good profile track once I get myself into a quiet room. Hopefully I can avoid doing any more coding if I find a better sample to noiseprof with, since the artifacts in my current work-in-progress track are barely noticeable. But if push comes to shove, I'll see if I can improve the sox effect or port the Audacity one to LADSPA... > I've also made patches which improve LADSPA support in SoX: > https://sourceforge.net/tracker/?func=detail&atid=310706&aid=3534109&group_id=10706 Applied in 14.4.2rc1 \o/ ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
