Recent Advances in Noise Reduction

Archiving and Restoration

Alexey Lukin, iZotope, Inc. - Cambridge, MA, USA

Since 1940s single-band and multiband gates dominated the field of static noise reduction in audio signals. FFT processing enabled by digital computers has dramatically increased the number of bands but hasn’t gone far from the multiband gate concept. Recent advances in deep neural nets are able to break free from the multiband gate approach by learning to predict signal features. This talk by iZotope’s Principal DSP Engineer Alexey Lukin will describe company’s evolution of noise reduction algorithms and provide some insights on what the future may bring for the audio engineering community.
