Description

Can convolution do realistic distorted reverberation? Or how to create a believable plate reverb sound in the digital domain?

Lecture by Giancarlo Del Sordo (CEO/CTO of Acustica Audio) and Nikolay Georgiev (plug-in developer at Acustica Audio, Past Chair of the AES UK Section, Recording Engineer and Educator). London, 22nd of September 2017. Venue: Dolby Europe London Office, 4-6 Soho Square, W1D 3PZ.

The main topic of this lecture will be on nonlinear convolution based on Vectorial Volterra Kernels Technology and distorted reverberation, with plates as a case study. In the presented technology the Volterra theorem is applied as a complete re-thinking, replacement, and substitution of the convolution algorithm that is commonly used in audio applications. The talk will also include a look into an original implementation of Partitioned Convolution not relying on the standard Lake/Gardner approach and some of the technical strategies for the practical implementation of low-latency, low-CPU consumption, real-time engine. Audio demonstrations of the so recreated plate reverb and other audio processors and distorted reverbs will be included.

This talk will consist of 2 x 50 min presentations plus refreshments courtosy of Acustica Audio. As usual we will continue the discussion at the pub after the event.
