Smooth moves using minim (music visualiser)

in Contributed Library Questions • 2 years ago

My question is really simple yet hard to find out with experimenting..

I want to do the following:

I have a 3D bird flying to the rhythm of music using minim line in.

To be more specific, it flies up and down. (Low sound = bird flying low, high sound = bird flying high)

Yet it's not moving smooth, it moves too fast to my liking. The logic thing that I would do is to use frame rate to slow it down but that makes the movement look like a slow browser loading an animation.

I hope it's clear what I'm asking here, anyone knows what function I should be looking for?

Are you using volumeSens() ? isKick/Snare/Hat ? FFT ?

Maybe you could use FFT, and make a counter that every frame moves to the next band in your FFT average - that way, the Y location will always smooth to the next neighbour... make sense ?

Thanks for your response, I use FFT indeed.

I understand what you are saying and I'll try to find out how to make a counter :)

Well just take an integer that increases every frame,

int count += 1;

reset it to 0 (or 1) when it reaches the same integer as your

fft.linAverages(this number)

is set to in your setup... then inside your for loop where you would normally visualize the fft bands,

for( int i = 1; i < fft.avgSize(); i ++) {

// here

}

do an assignment like

int now = band[count];

then you can even use the count variable to draw your bird x and y

image(bird, count, now);

.... or something like that (you may want to multiply 'now' to make it higher... for example)

Thanks for your help, I've been figuring out how to use your code in combination with what I have, but it won't work and it started at just the very first line:

int count += 1;

which I changed to int count = 1; and then worked, but now he says he can't find anything named 'band' so I've been trying to solve that for a while now.

Also, I don't use an image for a bird (I suppose you found that out for yourself and just took image as an example) so I don't know where I can put 'count' into the line where the 3D bird comes in:

scene2.load( dataPath("vogel.obj"), 1);

I tried doing this:

float[] band;

and then into the loop:

band[count] = fft.getBand(i);

int now = band[count];

and this gives: cannot convert from float to int
