“Limiter №6” mastering modular limiter
– 5 modules: RMS compressor, Peak limiter, High-frequency limiter, Clipper, True peak limiter
– high-quality signal processing to use for mastering purposes
– brickwall and soft limiting with different timing settings
– M/S and multiband modes
– optional 4x oversampling
– true inter-sample peaks (ISP) limiting
– analog-style indication
– 2 different GUIs
[Limiter №6] [Лимитер №6]
PS. If you want to fix my english in the manual you can use this [doc-version] to change. Thank you!
The latest version for arrangement of controls is on the picture. The concept called “big indicators” 🙂
The signal chain is: RMS compressor -> Peak limiter -> HF limiter -> Clipper -> True peak limiter
The plan is:
- Prepare public alpha version of limiter plugin. This version will have draft GUI but all functionality included and working.
- Prepare next release of Molot compressor.
- Take a break and make photorealistic GUI for limiter plugin.
Just did last changes in true peak limiting module allowing to clip sound without inter-sample clipping. First it was mentioned in this post. And this is the last version.
After that I’ve made union of all modules to new Limiter6 plugin mentioned here. Unfortunately it has too many parameters and without GUI and levels indication it’s truly brain damage to try to use it:
The concept was changed a bit. Now this is slow RMS limiter followed by very fast peak limiter followed by the clipper and ended with true peak limiting stage. All stages can be turned on and off. Peak limiter and the clipper can work in M/S mode. Peak limiter can also work as high-frequency limiter. The whole plugin can work in stereo mode for master or mix busses and in mono mode for instrument tracks which I believe can be useful.
The conclusion? I have to do simple GUI for it and try to use the plugin in sample projects to find its strongest and weakest points. That’s the way.
It’s -20 C (-4 F) behind the window, a lot of snow and I’m really disappointed with peak limiter module. So I did a try to enhance it. You can check this [peak limiter VST plugin (x86,x64)]. I think it sounds better this time.
Now I can continue to build up my new mega-limiter from all modules I have (see previous post). The codename for this project is now “Limiter 6” (in japanese it sounds like “rimitta roku” which I like).
On the first look it’s gonna be too many knobs and switches. So it’s really a challenge to place them all on GUI and make it usable. Maybe I should remove or hide some of them…
I’m continuing my work. Good luck!
I think I’ve got some kind of concept for upcoming clipper/limiter plugin. This plugin is planned to contain these modules:
- input clipper
- peak limiter (a.k.a “thin” limiter)
- signal limiter (a.k.a “thick” limiter)
- peak meter / output clipper
All modules are optional and can be turned off. Peak limiter has very fast attack/release and used only to limit peaks of signal. This “thin” limiter can optionally be used as HF limiter to limit only high-frequency components of peaks. Signal limiter has long attack/release settings to limit signal “body”. This “thick” limiter can be used in brickwall mode or in analog-style mode to pass parts of attacks through. Final clipper can work in inter-sample peaks suppression mode. And I think some high-pass filter to remove DC offset can be useful. That’s the concept.
Also I already implemented some ideas for peak limiter as test plugin. You can [download] it to check (Windows VST 32-bit and 64-bit).
What’s done in this test plugin:
- very fast attack/release limiter plugin
- only 6 samples of latency (in 44.1 kHz) so it can be used realtime
- it’s intended to limit signal peaks only so it sounds bad when limiting the signal “body”
What’s not done in this test plugin:
- no oversampling
- no inter-samples peaks detection
- no high-frequency limiting yet
So that’s it.
