Profile EQ and Resonance EQ processors at Sony CSL Open House 2018

24 January, 2019 | Emmanuel Deruty Matthias Demoucron

Our real-time audio processors Profile EQ and Resonance EQ were presented at the 2018 Sony CSL Open House.

Profile EQ

Profile EQ is a deep learning-based, real-time, zero-latency, multi-purpose, robust audio equalizer that is unique of its kind and represents a total novel in the industry. It uses a dilated residual network to provide an instant spectral balance of audio signals and has a wide range of applications: it can be used in every situation in which quick and/or automated spectrum balance is required.

Features:

  • Deep learning-based: A neural network reacts to the signal and sets the plug-in accordingly.
  • Real-time: The process is performed as audio is playing.
  • Multi-purpose: Improves a variety of sources, including when original audio is poor.
  • Zero-latency: Audio latency is 0 samples.
  • Robust: Easily adjustable to monitoring level and monitor grade.

Resonance EQ

It is a deep learning-based, real-time, zero-latency, resonance attenuation plug-in that uses a dilated residual network to remove resonances in audio tracks. It takes a more radical approach than comparable products in the industry. It can be applied to different situations, such as in pro and hobbyist audio production, but also in audio restoration.

Features:

  • Deep learning-based: A neural network reacts to the signal and sets the plug-in accordingly.
  • Real-time: The process is performed as audio is playing.
  • Zero-latency: Audio latency is 0 samples.
