released: SlickHDR

SlickHDRSlickHDR is a “Psychoaccoustic Dynamic Processor” which:

  • balances the perceived global vs. local micro dynamics of any incoming audio.
  • creates a rich in contrast, detailed and clearly perceived image which translates way better across different listening environments.
  • provides a convenient workflow by simply adjusting three dynamic processors to show a roughly same load.
  • offers further and detailed control about overall tone and release time behavior.

The stunning UI artwork and all renders were done by Patrick once again. Made with love in switzerland – as he said!

SlickHDR is a freeware VST audio plug-in for Windows x32 and you can download a copy right here: >>> DOWNLOAD <<<

SlickHDR – final teaser & release info

teaserSlickHDR is a “Psychoaccoustic Dynamic Processor” which:

  • provides a convenient workflow by simply adjusting three dynamic processors to show a roughly same load.
  • offers further and detailed control about overall tone and release time behavior.

Technically speaking, SlickHDR contains a coupled network of three dynamic processors with two of them running in a “stateful saturation” configuration and one based on look-ahead processing.

Fixed amounts of the unprocessed signal are then injected into the network at several specific points and also mixed back into the networks output. Being networked, all processors are highly interacting with each other and this is utilized to cope with a wide variety of sound (sic!) to balance the perceived audio dynamic range.

SlickHDR will be available around end of January 2014 as a freeware VST audio plug-in for Windows x32.

processing with High Dynamic Range (3)

This article explores how some different HDR imaging alike techniques can be adopted right into the audio domain.

The early adopters – game developers

In the lately cross-linked article “Finding Your Way With High Dynamic Range Audio In Wwise” some good overview was given on how the HDR concept was already adopted by some game developers over the recent years. Mixing in-game audio has its very own challenge which is about mixing different arbitrary occurring audio events in real-time when the game is actually played. Opposed to that and when we do mix off-line (as in a typical song production) we do have a static output format and don’t have such issues of course.

So it comes as no surprise, that the game developer approach turned out to be a rather automatic/adaptive in-game mixing system which is capable of gating quieter sources depending on the overall volume of the entire audio plus performing some overall compression and limiting. The “off-line mixing audio engineer” can always do better and if a mix is really too difficult, even the arrangement can be fixed by hand during the mixing stage.

There is some further shortcoming and from my point of view that is the too simplistic and reduced translation from “image brightness” into “audio loudness” which might work to some extend but since the audio loudness race has been emerged we already have a clear proof how utterly bad that can sound at the end. At least, there are way more details and effects to be taken into account to perform better concerning dynamic range perception. [Read more…]
