  1. 1. Evaluation of Methods for Sound Source Separation in Audio Recordings Using Machine Learning

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Amanda Gidlöf; [2023]
    Keywords : Sound source separation; signal processing; audio processing; speech enhancement; speaker identification; speech separation; speech processing; speaker separation; single channel; multi channel; cocktail party problem; machine learning; neural network; deep learning; deep neural network; convolutional network; dual-path network; filter-and-sum network; recurrent network; beamforming;

    Abstract : Sound source separation is a popular and active research area, especially with modern machine learning techniques. In this thesis, the focus is on single-channel separation of two speakers into individual streams, and specifically considering the case where two speakers are also accompanied by background noise.

  3. 2. Implementation and Evaluation of Encoder Tools for Multi-Channel Audio

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Tomas Malmelöv; [2019]
    Keywords : Scene based audio; 3D audio; Spatial audio; Ambisonics; HOA; Multi-channel audio; Audio compression; MPEG-H;

    Abstract : The increasing interest for immersive experiences in areas such as augmented and virtual reality makes high quality 3D sound more important than ever before. A technique for capturing and rendering 3D audio which has received more attention during the last twenty years are Higher Order Ambisonics (HOA). READ MORE

  4. 3. Real-Time Adaptive Audio Mixing System Using Inter-Spectral Dependencies

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Robert Koria; [2016]
    Keywords : Real-Time Audio Mixing; Adaptive Audio Mixing; Inter-Spectral Dependencies; Multi-Channel Audio Enhancement; Dynamic Equalization;

    Abstract : The process of mixing tracks for a live stage performance or studio session is both time consuming and expensive with assistance of professionals. It is also difficult for individuals to remain competitive against established companies, since multiple tracks must be properly mixed in order to achieve well-enhanced elements -- generally, a poor mix makes it difficult for the listener to distinguish the different elements of the mix.

  5. 4. Stereo Echo Cancellation(SEC) employing Signal Decorrelation with emphasis on Affine Projection Algorithm(APA)

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Santosh Ande; [2013]
    Keywords : Affine Projection Algorithm APA ; Stereo Echo Cancellation SEC ; De-correlation; Non-linear Processing NLP ; Time Varying All-Pass Filter TV-APF ; ERLE; MIS.;

    Abstract : Monophonic tele-conferencing systems employ acoustic echo cancellation (AEC) to reduce echoes that result from coupling between loudspeaker and microphone. Acoustic echo cancellation is simple to develope as there is a single channel. READ MORE
