I guess its not possible but I ask anyways:
Is it possible to access the spectrum values for a certain frame? I am asking because I’d like to make a prerendered version for an audioReactive piece by saving every frame as a .png. That obviously makes the music go out of sync thats why I am asking.
Anyways if it doesnt work i will try to write the fft data to an xml file first.
i don’t really know how to solve this, but i’m also facing the same problem.
i was trying to send the play head to the position i want it to be but the spectrum read i get are all zeros.
have you managed to solve this??
when people do this in processing, does the same problem occur? if so, how do they solve it?
hi, i think i kinda solved this. dont know how precise it is, but is seems to sincronize well.
its actually very easy.
this goes in the setup function
//music.length/music.internalFreq will get the length of the audio in seconds.
// multiplying by 30 because the video will have 30FPS
totalFrames = floor(((float)music.length/music.internalFreq*30));
counter = 0;
and this in the update
// just normalize the frame counter using the total frames and we know
// where we need to place the play head
float playHeadPos = counter/totalFrames;
i dont have any editing program but i made a video and audio player in OF and both audio and video seem to be well synchronized .
that seems to be a really easy method. what I did is that I wrote all the FFT data needed to an XML file and afterwards read the data for each frame.
I guess both is kinda easy amd quick.
