  • The Constant-Q Iir Filterbank Approach To Spectral Flux 
    Holopainen, Risto (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2012)
    Spectral flux is usually measured with the FFT, but here a constant-Q IIR filterbank implementation is proposed. This leads to a relatively efficient sliding feature extractor with the benefit of keeping the time resolution ...
  • Self-organised Sound with Autonomous Instruments: Aesthetics and experiments 
    Holopainen, Risto (Doctoral thesis / Doktoravhandling, 2012)
    Autonomous instruments are computer programmes that generate music algorithmically and without realtime interaction, from the waveform level up to the large scale form. This thesis addresses questions of aesthetics and the ...
  • Self-Organised Sounds with a Tremolo Oscillator 
    Holopainen, Risto (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2010)
    Tremolo is usually regarded as belonging to the domain of note embellishments. Rapid tremolo, taken into the audio range, is an interesting synthesis technique which is related to FMand granular synthesis. We present a ...
  • Smoothness under parameter changes: derivatives and total variation 
    Holopainen, Risto (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2013)
    Apart from the sounds they make, synthesis models are distinguished by how the sound is controlled by synthesis parameters. Smoothness under parameter changes is often a desirable aspect of a synthesis model. The concept ...
