sound affairs & audio effect design
Changes made within the 2.1 update:
As a side-effect it introduces 8 samples latency now. More and detailed information is included in the manual.

It’s so important to get the non-linear modeling right if we would like to have a sort of analog feel in the digital domain. I can’t stress this ever enough since it still seems to be a common practise in todays audio plug-in design to just throw in a static waveshaper, oversample it and hope this will make everything alright. Not! Even worse, in a recently released plug-in I saw the static waveshapers curve not being continuous again and I’m not going to talk about the sound.
But what should one expect to hear if the analog modeling is just done right? Only by driving the gain of the unit but way before we notice the obvious distortions there appear different by-products caused by circuit side-effects. Depending on the actual device, circuit and components, it might be that the signal starts just getting thicker and more mid-focused, as an example. Or, the signal might appear much deeper and bigger in other cases.
Whatever it might be in particular, I do call this the “Mojo” of the device – it’s not the primary intention of the device but turns out to be a sort of an added sugar. Such effects are highly frequency, transient and gain structure dependent and this is what makes the processed signal to be much more vibrant and alive. Furthermore, the obvious harmonic distortions are not introduced abruptly but they emerge gradually.
Rescue MK2 is the major overhaul of the analog style modelled signal designer already introduced back in 2007. It is a sophisticated mid/side based transient processing device which not only allows detailed ’3D’ imaging control but also fancy transient compression and distortion with dynamics that remains vibrant and alive.

Changelog for Release 1.0.1
The update is available in the downloads section.
Variety Of Sound announces mkII versions for NastyDLA and TesslaPRO to be released during Q2/2012. By this, all the sonic bliss of stateful saturation algorithms will be made available for both, the highly regarded classic chorus echo device with tape-delay simulation and the critically acclaimed “transient aware” signal saturator.
Stateful Saturation takes advantage of some sought after analog qualities and preserves them accurately during their transfer into the digital domain:
NastyDLA mkII remains feature wise the very same but introduces the input stage modelled by this new and exciting technology and also redesigns the tape compression algorithm for an improved IM distortion performance. TesslaPRO mkII will go way further by introducing a variety of different signal coloration options, ranging from console style distortion models up to typical mic/preamp colors.
More details will be unveiled during this month. Stay tuned!
Updates, basically. I’m still struggling with a preFIX update due to some technical issues I just can’t get, errrm, fixed (some VST hosts still do not respond to reported delay changes). Well, lets see how many month or years this will gonna take to work around or maybe then those hosts are just obsolete 
At least, I’m pretty much sure that we will see two other updates here during Q2: First, there will be a smaller update for the BaxterEQ where small is indeed the proper wording because it’s mainly about an additional but just smaller GUI version. [Read more...]
IMHO, its not about randomness (noise) in components at all. Its about the (very short) memory some circuits can deploy, depending on the overall load of the system. The shortcoming of the component modelling approach is still that the whole modeled system is deterministic (which is not). – bootsy
Around a year ago or so I’ve already started to look into a couple of stateful non-linear models which could be more suitable for a musical and convincing digital saturation experience. To make it even more harder, they should avoid the usual drawbacks such as huge latency or insane cpu consumption – if ever possible of course.
Meanwhile, my journey into the non-linear DSP land has made an important stopover with a first prototype implementation for such an approach, yielding a DSP core for musical harmonic distortion generation based on a stateful model. This opens the door for quite a number of interesting applications such as harmonic exciters or devices which needs convincing amp models whether thats a compressor output stage or even part of a guitar amplifier effect.

working with the oscilloscope
I’ve just polished the Blog a little bit and aside from some layout changes you will find all my actual plug-ins properly listed on the VST effects page now – including screenshots, short descriptions and some brief tips&tricks. If you would like to contribute and to share some further more of your own tips related to that stuff then this is the place to chime in – just drop them here as a comment or via eMail (if you already have my address). Furthermore I’ve collected lots of additional user comments for the testimonial page which looks really impressive after just two years of blogging here – many thanks for all your appreciation.

Tell us a little bit about yourself and how it came that you started develop audio effects?
I am both a computer scientist and a musician. To the time when the VST technology had emerged I’ve also started to move towards a complete ITB production. This took some years, though. During that time I’ve missed something in most existing software processors and so some own ideas arose. In 2007 I then finally started to implement the very first ones. [Read more...]
