Hi list,
I want to present some information at my PD site about my Diploarbeit at IEM.
[ The aim of this work is to research the possibilities of use the discrete wavelet transform in real-time with Pure Data for analysis / resynthesis of audio signals. With this intention I approached to a new sort of granular synthesis with Pure Data based on wavelet transform: resynthesis of an audio signal from its wavelet coefficients by means of an additive synthesis of wavelet streams (a temporal succession of 'wavelets grains' for each scale or frequency level which are enveloped by an amplitude factor obtained from wavelet analysis coefficients). Another audio applications by means of wavelet coefficients manipulation have been developed to study the possibilities of pitch shift, time stretch, equalization and audio randomization. ]
I have thought it could be interesting for people who is interested in wavelet transform and audio processing. Any criticism and feedback is welcomed. I seized the opportunity to thank Winfried Ritsch, for all their help and support during the course of my research at IEM, and also I thank Johannes Zmölnig and Thomas Musil for their help in PD programming.
