    Real-time Audio Processing via Segmented Wavelet Transform

  • Original language description

    In audio applications it is often necessary to process the signal in "real time". The method of segmented wavelet transform (SegWT) makes it possible to compute the discrete-time wavelet transform of a signal segment-by-segment, not using the classical "windowing". This means that the method could be utilized for wavelet type processing of an audio signal in real time, or alternatively in case we just need to process a long signal, but there is insufficient computational memory capacity for it (e.g. inthe DSPs). In the paper, the principle of the segmented forward wavelet transform is explained and the algorithm is described in detail.

    Zpracování signálů v reálném čase pomocí segmentované waveletové transformace

  • Czech description

    V audio aplikacích je často nezbytné zpracovávat signál v reálném čase. Metoda segmentované waveletové transformace umožňuje výpočet waveletové transformace diskrétních signálů segment po segmentu. To znamená, že může být využita pro jakýkoliv typ waveletového zpracování signálu v reálném čase nebo v případě, kdy je třeba zpracovat velmi dlouhý signál, ale nedostačuje paměťová kapacita.
