I just spent the afternoon trying to achieve this effect, with little success. Here is what I've been thinking, hopefully someone knows where I am going wrong, or has some information they can share on the matter. <br>
<br>There needs to be a fade-in of the spectral envelope applied to signal 1, ranging from all the fft bins equal to 1 when signal 2 is not to be heard to the fft magnitude of signal 2 (which is what the timbre.stamp.pd patch does) when the two are to be cross-synthesized. If the fade is supposed to go all the way until only signal 2 is heard, then the spectral envelope fade needs to be switched to apply to signal 1.
<br><br>Is there an easier way to do it? My attempt (attached) at doing only the first part (fading in the spectral envelope of signal 2 applied to signal 1) barely sounds more than a regular crossfade until the regular timbre stamping happens when the fade-in goes to 1. What I'd like to have is something that took more of it's 'timbre' from one signal than the other, and be able to fade this amount continuously.
