Waves Restoration and forensic cleanup

    Anyone using Waves Restoration for forensic work? I really dig it for light cleanup in mastering, but sometimes I feel like I'm chasing my tail when it comes to heavy cleanup of background noise on audio evidence tapes, etc. Sometimes it's almost to the point that I feel like I'm making it worse.
    I've played with the attack/release quite a bit and it helped, but sometimes it still seems like a crapshoot on the results. Any tips, tricks, hints would be greatly appreciated.

    Have you tried putting an eq plugin with hi and lo pass filters before the Waves? This way you can control what the plugin hears and thus what it will remove. This gives a lot of control and you can remove, say, the hiss wihtout the plugin getting hold of the mids, allowing you to really hit the hiss hard without affceting the mids. Its not perfect but just having the filters / eq in front of the Xnoise is soooooooo powerful, i often wonder why they dont include them in the plugin.

    Hope this helps.

    ps: so you do mastering and forensic work eh? interesting

    I have it at the radio station and just used the X-Noise plugin to pull out a bunch of air-handling noise in an old cassette recording. In 30 seconds, having never tried the plugin before, I managed some huge reduction in noise. Haven't gone back and really listened & tweaked for optimal results, however.

    You could find yourself a smart signal processing engineer who knows lots about Noise Mean Estimators and Detection Theory, etc. who could take your files and process them in Matlab - but you'd better have clients willing to drop some serious coin for the priviledge.

    That's generally what I do. I guess I'm just a little frustrated because I like my results to be consistent. Also, I'll run 2 plugs of X-Noise back to back. The first with a "learned" noise profile and the second with the Speech emphasis preset. Both used lightly.

    how long do you learn the noise for? The shorter the better in my book. And i mean just touch that button and release it!!!
