  1. 21. Adaptive content-based sound compression

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Markus Gerard; Marcus Tedenvall; [2019]
    Keywords : Technology and Engineering;

    Abstract : Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). READ MORE

    Abstract : This paper outlines the design of a high-precision graphic audio equalizer with digital filters in parallel, along with its implementation in MATLAB App Designer. The equalizer is comprised of 31 bands separated with a one-third octave frequency ratio, and its frequency response is controlled by 63 filters. READ MORE

  6. 25. Audio representation for environmental sound classification using convolutional neural networks

    University essay from Lunds universitet/Matematik LTH

    Author : Linus Lexfors; Malte Johansson; [2018]
    Keywords : Sound classification; machine learning; cnn; Mathematics and Statistics;

    Abstract : A convolutional neural network (CNN) training framework is described and implemented. The framework is used to train and evaluate an audio classification system, focused on evaluating differences in audio representation. The dataset used is ESC-50, containing 50 different classes of audio. READ MORE
