Dynamic 1073/84 EQ curves?

Yes we can! The 1073 and 84 high shelving filters are featuring that classic frequency dip upfront the HF boost itself. Technically speaking they are not shelves but bell curves with a very wide Q but anyway, wouldn’t it be great if that would be program dependent in terms of expanding and compressing according to the curve shape and giving a dynamic frequency response to the program material?

Again, dynamic EQs makes this an easy task today and I just created some presets for the TDR Nova EQ which you can copy right from here (see below after the break). Instructions: Choose one of the 3 presets (one for each specific original frequency setting – 10/12/16kHz) and just tune the Threshold parameter for band IV (dip operation) and band V (boost operation) to fit to the actual mix situation.

They sound pretty much awesome! See also my Nova presets for the mixbus over here and the Pultec ones here.

Dynamic Pultec EQ curves?

Wouldn’t it be great if the Pultec boost/cut performance would be program dependent? Sort of expanding and compressing according to the boost/cut settings and giving a dynamic frequency response to the program material.

Well, dynamic EQs makes this an easy task today and I just created some presets for the TDR Nova EQ which you can copy right from here (see below after the break). Instructions: Choose one of the 4 presets (one for each specific original frequency setting – 20/30/60/100Hz) and tune the Threshold parameter for band II (boost operation) and band III (cut operation) to fit to the actual mix situation.

major mkIII update for Density bus compressor released

[Read more…]

announcing Density mkIII – providing depth and dimension, mastering grade

As hinted earlier in a facebook post, the TesslaPRO update will be delayed and probably released after the summer break – it is just not there yet. Instead, a major update for the Density compressor plug-in already made it and it will going to see the light somewhere later this month.

So, lets talk about the Density mkIII update. During the last two years or so I’ve received quite a lot of feedback to the Density mkII release – mostly coming from mastering engineers – on how to improve its dynamic response towards todays mastering needs. Some very early efforts did not made it but with the learnings from the ThrillseekerLA compressor design and the emerging stateful saturation approach everything was possible, all of a sudden.

I do believe in feedback

If I would have to state just one single universal principle which life as a whole rests upon then I would probably refer to the principle of feedback. But don’t worry, I don’t want to indulge in rather esoteric directions here but just move on a little bit towards basic system theory and how this relates to audio processing.

(source: wikipedia.org)

According to classical control theory, such systems are taking its output information and feeding it back in to the process input and that way closing the loop – hence the name closed loop system. In DSP audio land, the information is the audio signal itself and the audio (feedback) path constitutes the closed loop system. Audio signal processors such as feedback compressors or guitar amp effects are good examples for specific applications. While the control theory provides a lot of guidance for closed loop systems e.g. on handling differential equations and stability criteria, this can get pretty much nasty in practise because of the potential manifold of feedback loops in the circuit and not just only the main audio path.

what I’m currently working on – Vol. 5

The constant lasting heat and humidity in the Rhein-Main area are driving me nuts atm and everything seems to be slowed down a little bit. Anyhow I’ve just managed to update the VST effects page with the missing preFIX entry including tips&tricks which might be extended over time. As a reminder, if you want to contribute some of your very own usage tips then please don’t hesitate and post here or eMail me and I will include them over there.

Beside that, some bugfixing efforts still takes their time for the preFIX plug-in. [Read more…]
