Hi Ralf, this works pretty good with my lowpass->rectify->aubio pitch detection. What I want to work on (once GuitarSynth is ported to DPF) is a source-filter analysis (see U Zölzer: DAFX) to extract the spectral envelope (timbre) of the guitar. As Zölzer putts it, it is then possible to obtain a neutral frequency analysis, that just the tones/frequencies without their attenuation due to playing technique. This is done simply by dividing the FFT'd input signal by the envelope. I think that should be done before the pitch detection. And anyway I want to convolve/multiply the envelope with the synths (as an option in the GUI). Then GuitarSynth will really be a guitar synth ;) Gerald
