42 Audio Illusions & Phenomena

In a comprehensive series of five YouTube videos, Casey Connor provided an awesome overview and demonstration of 42 (!) different psychoacoustic effects. Watching and hearing (headphones required) not only is so much entertaining and educational but also provides some deep insights why we all do not hear in the exact same way. Relevant for all of us in the audio domain whether it is sound design, mixing, mastering or development. Highly recommended!

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:

  • 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.

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.

The stunning UI artwork and render was done by Patrick once again. Made with love in switzerland – as he said.

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

It’s not about bending the laws of physics at all, it’s about understanding hearing and utilizing psychoacoustics. – bootsy

what Psychoacoustics is about

If you once listened to MPEG 1 Audio Layer 3 (aka mp3) compressed audio files you’ve already heard some encoding algorithms which are highly based on psychoacoustic principles. But what is that voodoo stuff all about in general? The science of psychoacoustics basically investigates the impact of a physical audio signals property on to the subjective perceived signal (hearing) and whats going on under the hood of that hearing, meanwhile. So it can basically be seen as an input/output model where a certain acoustic stimuli comes in and some sort of perception comes out. On top of that, hearing has not just been seen as a black box but a lot of modelling has already been done to get a better understanding on how hearing is actually performed in our bio-mechanical apparatus and our brain as well.
