EEL:Envelope-based Compressor
The script creates volume envelope based on volume level and compresses it.
1.gif)
=============
Old version(v1) info:
This is the initial version, in the future, probably, will change.
If any errors etc let me know.
This is not a copy of another script from spk77), although in something like(thanks spk77), but the principle is different.
This is not a compressor, although much like. Settings work a bit differently than in the compressor, although they have similar names.
I did not come up with other names. Because, in principle, they largely correspond to the compressor.
Old version Demo
=============
New version(v2) info:
The second version works like a compressor in peak mode.
Perhaps the rms-mode will be added if I have time.
In addition, LP and HP filters were added.
Added RT update mode (with each slider motion), you can watch all the changes live.
But do not use this mode on large ranges!
Buttons are replaced with checkboxes, it's much more convenient.
The interface is now more understandable for use.
How use:
Select the audio-item. Click "Activate Envelopes" and "Show Envelopes" if need.
"Show Envelope" - toggle show/hide take vol envelopes.
"Activate Envelope" - toggle activate/deactivate take vol envelopes.
Use the sliders to adjust take volume envelope.
Ctrl + drag - fine tune
Click on value - enter value from keyboard.
Dubble click - reset to default.
You can use the time selection to limit the area of application of the compressor.
Also, you can select more then one items. They will be processed separately.
The script works with mono, stereo, multichannel audio, any playrates etc.
===============
Link v1(old version):
Envelope-based Compressor.eel
Link v2(new version, will be updated):
Envelope-based Compressor v2.eel
Note: Needed SWS - latest version.
===============
How install - use Reapack, but the link to my repository must be added manually:
"https://github.com/EUGEN27771/ReaScripts/raw/master/index.xml"

Very very nice!
Interesting AudioAccessor using also. Seems very good in terms of performance (only with EEL, I guess).

Excellent! Well done!
P.S. BTW, is anyone experiencing this Reaper bug? It is not the script's bug! It's Reaper's and has always been there for me...

Very good. It is very fast.
I'm not sure if the output gain works as expected. I expected it to increase all points equally.

Yes, I see incorrect work in envelope "fader scaling" mode, I will fix it.

Fixed.

Eugen, could you add the ability to change values using the mousewheel? Thanks

Fantastic, thanks! Looks like kind of a revolution in workflow, which is coming!

This is really cool.
A few ideas:
Do you think it is possible to have a side chain of sorts? Maybe a drop down to select a different track?
Adjust the settings to allow for expansion as well as compression.
Great work!

That is excellent work Eugen.
I know little of EEL programming, barely know of jsfx syntax. Here is not a suggestion, just something you might consider if you like the idea--
It would probably need allocation of an array of temp memory for the envelope points, unless it is easy to poll previously written track automation events.
You could first scan backwards from the end of file to beginning of file to write/smooth the lookahead envelope, and then scan from the beginning to the end of file to further smooth in the forward direction.
If doing backward-forward smoothing in this fashion, I think maybe you could get away with instant attack, programmed release for each scan direction. If scanning backward instant-attack, 10 ms release or whatever, the release of the backward scan would actually be the lookahead attack of the final envelope after both the backward and forward passes have been completed.
And then the second scan, the forward instant attack, programmed release scan, would keep the "attacks" established by the backwards pass, and add the conventional release behavior.
Maybe you could keep the current attack and release user interface controls-- Merely that the user-entered value for attack would actually be used as the release value of the first backwards scan.

Not sure that'd work very well, as the script would update on every mwheel event, which would be a lot. I might be wrong though. One could also probably limit the interval of the update too.

hmm
I wonder if this script could be tweaked to do upwards compression too?
Whereby, peaks are left alone and the quiet bits are turned up rather than the peaks turned down
That would be very cool too!

Mini update. Now it supports work with multiple items. And time selection.

Super useful, as usual.
Might I suggest adding noise gate, to be on par with SPK77's script in terms of a workflow? It would be a great addition to process vocals.

Tried it on acoustic guitar.
Very good results!
But, only first item, and no save/recall settings is not so good for workflow.

Indiscipline, maybe in the future.
G-Sun, Somehow the link was an old version. I re-updated the link, multiple items and time sel now supported.

Happy to hear that.
Option to use pre-fx vol env. instead of take vol, could be nice as well.

Call me stupid, but what are the differences and advantages/inconveniences with a classical compressor ?

Tried it out, works very well.
Thank you!
Now, a lot to be desired.
Presets, hpf, numeric input, normal values, expander, rms-setting.
But, it works

Looks exciting but do not work with my system.
interval, Outgain, activate and Show envelope work ok but all points always stays in a sad straight line... Anyone else encountering this issue ?
By the way I'm on mac osx 10.8!

Yes, I have found that this (sometimes?) happens if the item already has its volume adjusted. What I have to do in those cases is to lower the threshold extremely low, and then raise it. I have not experimented with this yet, so I have no better description. And this is on W7x64 REAPER 5.40/x64.

I got the same impression yesterday but then realized that the script is time selection (and/or loop selection) sensitive. So it's only active in that area. Be aware of that.
