Multichannel audio coding and transmission

• Use of multiple channels in audio capturing and rendering offers the advantage of recreating arbitrary acoustic environments, immersing the listener into the acoustic scene.
• Multichannel audio contains a large degree of information which is highly demanding to transmit, especially for real-time applications.
• Designed and tested coding schemes based on multichannel audio-specific models, namely.
  • the source/filter model and
  • the sinusoidal model

which allow for flexible manipulation and high-quality, low-bitrate encoding

• Blind source separation for audio signals. Emphasis on non-linear mixtures (e.g. when sound recordings suffer from saturation or clipping.
