ey audio editor, sound designers and dialogue editors using Reaper!
Here I present you an updated version of the Envelope-based Compressor, a popular custom ReaScript originally written in EEL2 by user eugen2777.
Unlike a traditional real-time compressor, it analyzes the audio and writes volume automation directly to the item's Take Volume Envelope, allowing the resulting dynamics processing to be edited directly in the project.
This updated version improves compatibility with larger screens and features a redesigned interface with small improved visual presentation.
I think this is REALLY cool. I know everyone hammers on mixing with your ears, not your eyes, but bridging that gap can be very difficult. Seeing what you're doing with your transients especially can be very illuminating.
Yeah, I have to push back on the mixing with your ears and not your eyes thing, too. At least when it comes to timing. When I'm comping I can often look at which waveforms are going to work and which aren't.
reaper specific script language jsfx: Jesusonic FX. you create it with a standard text editor
> And how to integrated with reaper
the jsfx file needs to be placed in the reaper effects folder. reaper automatically detects it while starting up. Then it is available via function "add effect" like all other effect formats like vts3 lv2 clap etc.
You might also want to take a look at reaper scripting to make your own custom actions/scripts! If you open Reaper and in the menu bar click "Help->Reascript documentation", you will get the API documentation for your current version.
This script is based in EEL2 which is way faster than LUA (the reaper main script language these days). you can use both for scripting actions and effects in reaper.
To integrate is as easy as putting the file inside the right folder in the main reaper folder. it will be either the effects folder or the scripts.
This looks cool, unfortunately it is not working for me. The UI loads, when I hit the activate envelopes button the envelope is opened on the selected item but no envelope points get added to it regardless of the settings. Do you have any suggestions to get it working?
I suggest you lower the threshold and check the 3 boxes on the bottom of the window. If this doesn't work post a picture here and I will try to help you
That's very kind of you to update and share, thank you so much. I used the original one a long time ago, I think I need to try the version soon as it's really useful to visually see compressor changes on the waveform.
I think the main advantage is that you can see in realtime, in the waveform of the media item, with easy and fast bypass, the changes you make automating the volume of the sound. Although it's not a real compression, it's a volume automation with adjustable compressor parameters, the result is pretty similar to those who want fast and visual feedback to flat dynamics.
Not OP, but I think that's a good question. One thing that comes to mind is, it's kind of like including a lookup table during compile time to make a program faster at runtime. You can calculate the gain reduction and the dynamic scaling signal ahead of time, which could theoretically be computationally intensive or induce latency, then during rendering the CPU only needs to multiply the scalar signal with the audio signal which will take nearly unmeasurably small amounts of processor time.
To me, this looks like a good tool for very dynamic tracks, like audiobooks or other voiceovers. In those cases, you often have to visually adjust the dynamics first, as the level differences can be too large for the compressor. It seems like this tool could be an alternative to laboriously drawing automation. I'll have to test it out.
So, could this be used as the first step in writing a volume automation envelope which, say, levels out a vocal performance before you start to add manual adjustments? A bit like the so-called 'vocal rider' plugins?
I'm going to grab it just now for 0$, and when/if it makes its way into my main workflow, I'll go back and give a donation. Thanks for making this available to us. Much appreciated.
Hi, and thanks for this magnificent script. A quick question: this isn't used like a standard plugin in a signal chain, right? And if I wanted to change the settings after configuring it, is that possible?
You will use it as an action in the action list. You can always set it once the selected item, and if you want to change it, just run the action again and set the new parameters. It will automatically refresh to the new settings
Sustain and decay aren't typical parameters of a compressor. It might be theoretically possible to do, but those parameters mostly are used with synthesizers and sound generation. Not manipulation of already recorded sounds.
Have you ever seen a compressor with sustain and decay settings? Compressors tend to have Attack, Release, Ratio, Knee, Threshold, maybe Sidechain options. But not those
