There was some disscussion here about the dynamic range of fixed point FFT. The simplest way around it is to scale down the data before the conversion, but has anybody changed the TI FFT asm code to incorporate a 1/2 factor scaling between the butterfly stages, and so preserve the dynamic range of the data?
