TDR Nova compressor transfer function

Let’s talk a bit about compressor transfer function used in TDR Nova.

(a lot of boring text follows)

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.

[Check it here]

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!)

Molot Compressor AU version

Dmitry Baikov (c0ff) has developed AU version of Molot.

See details in these threads:



I’m (Vladislav Goncharov) is not developer of this port so please don’t ask qustions about AU version I just can’t help you 🙂

Molot Compressor VST Mac OS X version (TEST ONLY)

Hi there!

I spent a couple of evenings to try to compile Molot VST on Mac.

The result is the OS X version of VST plugin that you can try to use but I don’t promise you this version 100% working.

Current issues:

  1. There’s 32-bit version only (x86 and PowerPC platforms). I had problems to compile VSTGUI for 64-bit version.
  2. Checked only for Reaper as VST host both x86 and PowerPC versions.
  3. There’s no my favorite EN/RU switch. I had problems with VSTGUI for dynamic changes of transparent layer with english “paper sticks”.

[download 0.2.145 (32-bit, VST, Mac OS X)]

Feel free to write what do you think about this version in comments. Any help is appreciated.

Molot compressor updated to 0.2.145

New version available in download page. What’s new:

  • New upsampling code: latency now 2 samples
  • Faster limiter release
  • Fixed bug with preset names changing

Новая версия доступна на странице загрузки. Что нового:

Новый алгоритм передискретизации: задержка теперь 2 отсчета
Уменьшено время релиза лимитера
Исправлена ошибка с изменением имен пресетов

I used previous version of Molot in some projects and I think the limiter was too soft and too slow. As the main idea for limiter in Molot is to control peaks in sigma mode I changed limiter settings to more aggressive.

Also I have a lot of fun pictures for new post about some experiments with different upsampling algorithms (step, linear, polynomial, sinc function). It’ll come soon.

Molot compressor updated to 0.2.135

New version available in download page. What’s new:

  • New limiter code
  • Larger GUI
  • Release curve reverted to 0.2.121 version

The limiter is far from ideal but much better than it was. Remember that the main task for limiter in this compressor is to soften (but not 100% suppress) peaks passed through in sigma mode.

Версия обновлена и доступна на странице загрузки. Что нового:

Новая версия лимитера
Больший размер GUI
Кривая релиза вернулась к форме от версии 0.2.121

Лимитер все еще не супер, но все же лучше, чем был. Напоминаю, что основная задача лимитера в этом компрессоре – смягчать (но не на 100% подавлять) пики, прошедшие сквозь компрессор в сигма-режиме.

And just for fun I found this old picture:

And also the first concept of GUI:

Have fun!

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.

Molot Compressor updated to 0.2.130. And a few words about EQ [или немного про эквалайзер]

Molot Compressor updated to 0.2.130. Check this out!

What’s new:

  • Release curve was slightly changed (a bit shorter at small signal values).
  • Frequency response in oversampled modes changed to be more linear.
  • Limiter has become softer.
  • When user-adjustable sidechain filter is off now built-in lowshelf sidechain filter applied.
  • Some presets have oversampling off by default.
  • Latency was fixed to be 3 samples (was declared as 2 samples by mistake).


If you dislike sound changes in new version you can download old versions. See the links at the bottom of Molot Compressor page.

Версия обновлена до 0.2.130. Что нового:

Немного поменялась кривая релиза (чуть короче при небольших значениях сигнала)
АЧХ при передискретизации стала немного более линейной.
Лимитер стал помягче.
При отключении сайдчейн-фильтра теперь подключается встроенный low-shelf фильтр.
В некоторых пресетах по умолчанию выключено использование передискретизации.
Вносимая задержка исправлена на 3 отсчета (ранее ошибочно декларировалась, как 2).


Если вам не понравились изменения в звуке новой версии, вы можете скачать любую из старых версий. Ссылки внизу основной страницы компрессора.

And now about EQ

“Molot” VST Compressor is ready! Some words about GUI creation (или немного про создание GUI)

“Molot” compressor VST plugin page is [here]. And in this note there are some words about GUI creation.

Страница VST компрессора “Молот” [тут]. А в этой заметке немного про создание GUI.

The idea was to make GUI with old Soviet military device look. As I’m not an artist I started to search real device as basement for GUI. I spent some time to find old military looking devices in old stuff from garages of my friends and finally found very interesting looking device. It’s cathode voltommeter A4-M2 USSR, 1956. Check [this] out.

Возникла идея сделать интерфейс, выглядящей, как старый советский военный прибор. Так как я не художник, то решил поискать какую-нибудь реальную железку, чтобы использовать ее в качестве основы для GUI. Поспрашивав некоторое время у знакомых, не завалялось ли чего в их гаражах, в конце концов нашел очень интересный аппарат: катодный вольтомметр A4-M2, СССР, 1956 год. Вот [такой].

 This is it in my kitchen:
