NastyDLA – technical architecture

NastyDLA - technical architecture

simplified technical architecture

Internally, NastyDLA consists of quite a bunch of DSP processing building blocks which as a whole are summing up to an authentic signal path simulation of it’s analog models. The blocks and the according signal flow are shown in the diagram above. Basic signal flow goes from left to right except the feedback path which goes in the opposite direction.

With NastyDLA, signal path coloration already starts in the input stage which provides a complete model of both, frequency and phase response as well as dynamic saturation. It’s located in the dry path but all nonlinear processing and coloring can be disabled on demand so it remains as a simple input volume control then. But while switched in, the input stage can greatly contribute on getting the processed signal to fit right into a mix. [Read more…]

NastyVCS – I can has color

NastyVCS tubeSimilar to the EQ’s and filters in BootEQ mkII, NastyVCS stays on the musical (and not the surgical) side of the audio source. It is more kind of coloring toolbox (especially in the combination with the PHASE option) rather than allowing to shape audio disfigured beyond recognition. Some classic technical principles have been carefully selected and replicated and the overall combination and attention to detail makes NastyVCS stand out in the crowd of equalizers today.

from phasing to phase alignment

In the recent article about audio signal coloration I’ve already talked about the importance of the signals phase response in respect to the perceived tonal spectrum and today I’m going straight ahead towards phase alignment and how a signal delay relates to the phase response. But first let’s have a look at some nice youtube stuff showing Jonathan Little on demonstrating his Little Labs IBP phase alignment tool.

about audio signal coloration

In this comprehensive article some deeper explorations and explanations on this topic are given and at the end a brief but handy definition about audio signal coloration is proposed.  Some tips on mixing can be obtained here as well and – by the way – some myth about equalizing audio in the digital domain gets busted.

the beauty of opto-electrical compression

PhotoresistorOpposed to VCA, Variable-Mu or FET based approaches, opto-electrical compression takes advantage of using a light-sensitive resistor and a small light emitter (a LED or electroluminescent panel) to obtain a gain reduction voltage in the sidechain path. This technique is well-known to add some smoother gain riding characteristics to the signal because of the specific attack and release response which comes from the inertia and inherent memory effect of the photoresistor element.

applying saturation through the sidechain

This short article gives a brief introduction on applying waveshaping algorithms not directly in the audio path but via a transformed equation through the sidechain and a VCA instead.

Density mkII – reworking the audio engine

While working on the Density overall re-design I was working extensively on the audio engine as well but just for one single reason: The one thing I was missing in the original design was to have some more “responsive” gain riding possibilities but without the usual tradeoff of introducing more distortion or compromising the transparency. And (unsurprisingly) that turned out to be not that easy.

the compressors sidechain: filtering

freqThere were already an excursion here about the design of compressor transfer curves over here and now this article turns on to the design of the sidechain path of a compressor in general. One major part of the sidechain design of a compressor is the filtering and thats the topic here for now. [Read more…]
