so - with explosions, you mean your algo becomes unstable for certain settings? how is this related to the samplerate? is it such it tends to become more unstable when...

ah - the unit delay in the feedback path. i wanted to suggest something from ODE solvers: even if the ODE (system) itself is stable, the numerical solution procedure can...

> if the instability/explosion starts out as a parasitic oscillation at the nyquist-frequency (i sometimes observed instabilities manifesting themselves this way) here this is happening for a PDE in the...

yes - indeed - but as said, the idea may very well turn out to be crap. but maybe worth a try nevertheless. if you can point me to the...

for filtering, the trafoSize should probably stay fixed at being equal to the blockSize. i think using zero-padding (i.e. trafoSize > blockSize) makes sense only for higher resolution analysis and...

yes, that should work, too. i'm currently just not sure, if the subtraction will work correctly on the spectrogram level due to the flaws and/or bugs in the matrix class...

> is it ok to use float types with rsSpectrogram? i didn't try that but don't see, why it should be a problem. you should just need an appropriate template...

> What's the demodulation thing about? What is modulation in this case? before analyzing a frame, an analysis window is applied and after (re)synthesizing a frame, a synthesis window is...

> I get some distortion at the end of the file :-O what is this?! i've never seen that. what are your settings? maybe i should try it with your...

oh - i just noticed that the hopsize should be blockSize/4 and not blockSize/2 for the overlapped windows to sum up to a constant (with the Hann window). blockSize/2 would...
