Good afternoon,
I need to to apply fft()function to recorded audio and also apply highpass filter through it at different frequencies. It graphs just fine but i need help playing sound. I was thinking of storing each graph in an array and playing each sound at each position of the array, but i'm having problems storing these signals in an array.
Is there a more efficient way on doing this?
Please help and thank you.

Store the filtered signals in a cell array (easiest). Then use the playblocking function to play them back one after the other so they do not all play at the same time.

Another question,
If i wanted to preallocate my cell array how would i do so for this example?
would it be like this?
fourier_array = cell(1, length(HIGH));

Yes.
That worked when I tried it.
