I'm working on EVAL-ADAU1467Z based SigmaDSP. Due to my application requirement, I have to estimate the frequency of the incoming signal (specifically audio signal) at every instant of real time. i.e. something like estimating the instantaneous frequency of the signal. Only if I know the frequency ( at least the frequency band of the incoming instantaneous audio signal, so that I can take the centre frequency of that band to roughly attribute for the frequency of that frame of audio), can I proceed with next stages of my algorithm. Hence, I looked out for blocks of sigma studio ( Ver 4.2 / for 64 bit OS) to do this task, but couldn't get a one.
Can anyone help me out in accomplishing this task? Thanks in advance.
