unicomb / delay / vibrato

1) unicomb filter 'all pass' mode implemented

• calculations too long; why?

• spectrogram plot: search/make something decent

• watch out with commands wavread and wavwrite --> you have to give the right sampling frequency, otherwise your sound is totally distorted, while it's not the fault of your algorithm

• we worked on a vibrato, nut didn't succeed; maybe just because previous point :( --> we should try it again !!

2) to implement delay mode

• problems with calculation time... not able to use it because of duration/ why?
• a delay with parameters M=20000 so approx. 0.5 seconds results in no sound when using La.wav (it's own duration is also 0.5sec) This is because everything falls outside the window then. But do you have to sum the original signal with this one? Because it seems that this is already done in the figure (DAFX ch3). --> We must sum, it is NOT done in the picture

3) vibrato

• same problem: too long ! frustrating !
• ok, it was because of the parameterchoice... shorter, but still not short enough.
