I've been doing FFT's (on sound) for a while and usually use the highest intensity or the ones above average to get the spikes in an FFT result.
What would be a good method to get all the 'spikes' in an FFT. I can't use averages or peaks because the frequency response drops off. Visually its quite obvious there is a spike but I can't get a way extract the frequency from the spike.
Low frequencies always tend to have a higher itensity than higher ones but don't necessarily have any spikes in them.
Are there any good reliable techniques for this?
