RMS limiter module enhanced

Okay, I have started making the new limiter from all modules I have.

The signal chain will be: DC Cut Filter -> RMS Limiter -> Peak Clipper -> Peak Limiter -> Output Clipper

  • DC Cut Filter – to cut unnecessary lows (and to remove DC offset);
  • RMS Limiter – to stabilize crest factor and to average loudness;
  • Peak Clipper – to cut very strong peaks to help peak limiter not to “thump” on them (can work in M/S mode, have different knees to switch);
  • Peak Limiter – to limit peaks (can work in M/S mode, can work as high-frequency limiter just to soften the sound);
  • Output Clipper – (can work in true peaks mode to avoid inter-sample clipping or in simple mode just to clip samples, has switchable auto-gain mode to automatically level up the sound to -0.3 dbFS).

Maybe soft-knee control can be useful for Peak Limiter (I’ll check this soon). Maybe DC Cut Filter is better to place just before output clipper (I’ll check this later). I have no ideas about GUI yet.

By the way, I found that use regular compression curves with no high ratios (4:1 for example) for RMS limiter is better than limiting curve. I reimplemented the last RMS Limiter module (see previous post) with “Ratio” parameter and I think it sounds now pretty good. (Actually, I love how it sounds :-).) If you interested in you can check this [RMS limiter VST plugin (x86,x64)].

Good luck!

PS. I think the idea to show each small step of development of new plugin is better than keeping silence for year and after that to show only the last final step: the release version. I prefer continuous development process on each step of that you have something to check and to listen.

Molot compressor updated to 0.2.155

First, we have new skin (see here):

Next, I added some new parameters.  Molot was initially designed for input levels of -12 dbFS so you have 12 dB of headroom. If you have your levels for 0 dbFS or even more than that Molot can distort your sound. It is sometimes pleasant sometimes not. Now we have input gain control and built-in saturation can be turned off. By the way the saturation was always the part of Molot sound and saturation control was linked with “Ratio” knob. So the more ratio you set the more your sound was saturated. Now the saturation can be independent from ratio value. And finally you can place limiter at the end of signal chain or turn it off if you dislike it.

NOTE #1. Only Windows version was updated. Mac version will be updated soon.

NOTE #2. As the number of VST parameters was changed some DAWs I beleive don’t handle right the plugin upgrade in existing projects. So be careful! (I checked plugin upgrade in Cubase only and it works fine!)

New Molot version with new limiter and larger GUI is almost ready but now some words about compression [или немного про компрессию]

In this post I want to show how the Molot compressor works and show visual difference between sigma and alpha modes, harder and softer knees and changes between 0.2.130 and 0.2.121 which I want to revert in the next release.

 В этой заметке будет показано, как работает компрессор “Молот”, будут показаны визуальные отличия между режимами “сигма” и “альфа”, мягким и грубым переходом и отличия между версиями 0.2.130 и 0.2.121, которые я собираюсь вернуть к старому варианту в следующей версии.

First get such kind of test impulse signal. 5 kHz of -3 dB for 1 sec and -12 dB for 1 sec.
