De-reverberation - The final cut

No modulation, no absurd excess.

For ease and whizz here is an A/B/C/D comparison using the McKenna file I initially uploaded.

1: original recording (no reverb added)
2: original recording treated with a plate reverb
3: reverb reduction by pluginnow
4: reverb reduction using a commercial noise reduction plugin

The pluginnow treatment does actually work a lot better than standard noise reduction, though both methods basically destroy the audio content like a harmonic filter.

plugninow, maybe you can post a file? You know what you need/want.

[Rock]

it sounds like you are getting phasing effects on the original with this

[pluginnow]

Ok, give me my chance

Instructions:

Listen first the original. Then the de-reverberated file. Then the original again, 2 or 3 more times, in this particular order.

Check the last part of the files AND her voice. With just the voice, it would be possible much more.

The stereo isn't intact like it was supposed to be, but it's late here, and I'm not getting more on this tonight. (I think I got it almost mono, but it's really possible to do absolutelly stereo!!)

So, you will see the algorithm try to take every part of the reverberation, leaving only the modulated signal (hardest part, but it's possible to have a complete stereo effect like this). Everything else is removed in a range of about 700ms.

2 stages were used. The algorithm is still fresh, give me some days.

Ps: Don't forget to match the volume!

Oh dear, back to the drawing board on that one methinks.

[pluginnow]

There was a problem!! Tommorow you'll eat the hat!!!!!

ed: forgot to remove the out-of-phase only signals

Need as it is some improovement to be usuable, of course, but looks promising

( ...maybe we'll see later today if a hat is still something eatable )

on the basis of the reverbreductiondestruction example, it's not too bad, considering some people think it's impossible to do at all. it's not so far-fetched either - with the kn0ck0ut VST i've messed about with something i figure might be similar. trick is to _add_ reverb to the track you want to kill it on that is as like the reverb y're trying to get rid of as possible, route that reverb signal only (no dry signal) to a send, and then spectrally subtract it from the original using kn0ck0ut, playing with reverb and levels for best result. not amazing outcome, unavoidably degrades the original (s'why i never put it out there), but can be as good as this, or sometimes better (as i guess pluginnow's technique would be) on some source material & if you happen to have the matching reverb to play with...

I sincerely hope you will succeed pluginnow. Keep your spirits high.
You've put a lot of pressure on yourself by starting this tread. I'll drink to that.

Try that knOckOut plugin on that last song and see what you can do...

I'll post my last efforts later, too.

most often my posts are too wordy...this time I should of typed more, my apologies...my point though was simply that if it only works when you need to remove a little reverb there are ways to solve that with a compressor and/or sidechain...but having never been in the position to do so I'm not exactly the expert on it. I tend to think that reverb is generally way overused to begin with. Fortunately I'm alone doing my music, I'm saving my tracks and mixes, so I can go back and fix it if the need is there. Generally speaking I record my tracks dry and monitor with fx. Especially on my song Aint Got Much to Say where the delays were a critical part of the feel on the guitar (both electric and acoustic), and the overall reverb sets the mood of the song (imo, in this song I put reverb on the bass which is quite rare for me).

So when I said no point, what I meant was I can only see the need for such a pluggin in my narrow view for extreme situations, if it won't work in those situations (and being over zealous with the sustain on a piano might be one place I could easily see myself using it), then there seems to no point for me.

Now of course tonite I'll be doing something and I'll need just such a pluggin...

[living sounds]

I listened to the file you provided - it does certainly remove reverb, except for the early reflections. I don't hear denoiser artifacts on the Bjork track (although there is something missing other than reverb missing from the signal).

[eidenk]

So how does it fare with the out-of-phase only signals removed ?

My hat is ready.

No further devellopement in the saga ?
