Nice picture and no comments

VoS + TDR = ?


What can I add for this? First, it is a great pleasure to work with these guys. Next, we have a project to be released very soon. And we’re going to release 64-bit version for it. And we’re going to release Mac version too. And… Okay, no more information for today.



Just for fun: “T Analog Channel” plugin

(where T stands for “troll”)

I had a part in great discussion about “wider” sound of analogue consoles. Check upcoming AudioTechnology Magazine issue, BTW. During this discussion I developed some kind of proof of concept plugin just to check possible reasons of wider sound. This developed plugin acts very subtle so most people just can’t notice its action! That’s why it’s “troll plugin”. You can use it for this purpose ;-)

Add this plugin to each track and bus of your mix and feel analog vibe added!

Technically, the plugin applies very small amount of random EQ to L & R channels, adds very small amount of 2nd harmonic, adds small level of white noise and slightly widens frequencies around 10 kHz. Also it has “Gain” control and thus can be used as smooth gain fader.

Also, I want to say big THANK YOU for all who donated. You give me the reason to continue my efforts over and over again!

Okay, it’s time for further research and development. There’re pending little fixes for Limiter6 and Molot. And I have a dozen of new projects in my head! Please, be patient ’cause I didn’t stop my research work. :-)

Red Rock Sound C1-L1 official explanation (for Propellerhead Reason users only)

I’m getting dozens of e-mails asking me about Red Rock Sound C1-L1 Propellerhead Reason rack extension plug-in. I want to answer these questions here. 

1. I’m not related with Red Rock Sound and I don’t work for them. So I can’t make any statements about their pricing policy, the product quality, stability and customer’s support.

2. Red Rock Sound use Molot sound engine from my permission. Molot sound engine was given for fee and with terms of usage.

3. Molot sound engine given to Red Rock Sound was matched to version 0.3.1 of Molot compressor but lacks of linear phase oversampling.

4. The GUI of “C1-L1″ is not a copy of Molot GUI but they both use the similar style of Soviet military equipment. Both authors are Russian guys and we both like such kind of look and feel, which is not prohibited. Also both plug-ins use the same voltmeter model for VU meter.

5. Authors from Red Rocks Sound are working on re-writing the manual, which was very similar to Molot one.

6. I didn’t have and don’t have plans to make Reason rack extension version of Molot plug-in. Also I don’t have plans to release commercial version of Molot.

Thus, Red Rock Sound C1-L1 is “based” on Molot compressor but is not the copy of it.

How to describe the sound of a plugin?

First, check this very cool article:

[Psychology of a Mix Engineer: Chris Carter]

And this is the most interesting (for me) part of it:

Q: What’s your go to digital compressor and what are you listening for when you use it?

Chris: There’s a few that I use very frequently but the one that I go to the most is probably the freeware guy called the “Molot”. It’s made by this Russian dude and I frigging love the thing. It’s got two modes and they are supposed to mimic a Neve 33609 and a Fairchild 670. I don’t really think either one is convincing but I don’t really give a rats ass how accurate it is [laughs]. I pretty much just use it in the “Fairchild 670″ mode. I don’t know what the heck is up with that guy but he understands attack and release characteristics really well. It’s almost damn near impossible to get that thing to sound bad, I swear to God. That’s my generic utility compressor because I like Optical Compression a lot.

Now, let’s talk about the thing that bothering me. After 2 years from Molot release, I think that mention of “Fairchild 670” and “Neve 33609” compressors in the description of Molot sound was not a good idea.

Imagine, I did Molot and now I should describe, how does it sound?
“The most accurate emulation of…?” No, it’s not emulation of anything.
“The most transparent sound?” No, it’s not transparent.
“Bus compressor?” No, it wasn’t designed in such way.
“Track compressor?” No, it’s too heavy to use on each track (at least 2 years ago).
“Mastering?” No again.
“Tube compressor?” No, I didn’t implement any kind of tube emulation.
“Opto compressor?” No, it doesn’t mimic opto-cell behavior (it has fixed attack/release times and feed-forward compression).
“Powerful?” No.
“Flexible?” No.
…and so on…

My initial description of Molot had words about “aggressive hammering sound” (don’t forget “Molot” is a “hammer” in Russian), “suits well for rock drums”, etc. I think, this kind of description is not correct, because I tell you where you should use this compressor and where you should not, e.g. I limit your creativity.

I already forgot the details but it was told, the compressor sounds like Fairchild in alpha mode and like 33609 in sigma mode. I never heard either real Fairchild or Neve. Also I didn’t try to emulate their sound. But in my opinion this description was better so I used it. Now why I’m so unhappy with it? It’s like “What kind of music does your band play?” question. “It’s like Children of Bodom”, that’s the answer. “Well, you band mimics CoB sound then.” And finally it looks a bit like the sound was stolen…

Current version of Molot page doesn’t try to convince you to get this plugin. Instead, it contains reasons why you shouldn’t do it! Freeware plugin can afford this :-) Really, I don’t want to change this. And I think, it’s cool! What is my final definition of Molot sound then? Check this out. It’s a dynamic tool to add a character to the track. It tends to make your sound “fat” and adds some feel of old guitar amp.


I also like the free Molot for smooth color. I use in on the 2buss after hardware comp just cause I like the sort of soft cushion or sag it gives.
Sort of like rectifier tubes in a gtr amp.

Yeah, yeah! That’s about it!

So what? In some future I will have the same problem to describe the sound of a new plugin. And I think, I’m ready for it!

IIR based EQ and distortions

“IIR” stands for Infinite Impulse Response. This is one of possible ways to implement digital EQ. This way is very CPU lightweight. But it’s impossible to make linear-phase EQ using IIR. So the most digital min-phase equalizers are IIR.

Let’s get cookbook peaking filter formula and make simple EQ. We’ve got such a nice curve:


Next, move frequency up to 10 kHz (we’re on 44.1 sample rate) and see that:


You can see now, the perfect symmetric shape of “bell” is distorted and not symmetric now. How does it sound? Such non-symmetric curve has harsh, sharp, “digital” (in bad meaning of word) sound. But bell shape of true analog EQ doesn’t distort here. I think, symmetric curves sound more natural to our brain and thus leads to better sound perception.
