Buffered FFTs are most useful when you want to do non-realtime processing. Streaming FFTs are best for realtime contexts when you don’t want to handle buffering yourself. (In fact, fftstream / ifftstream use fftbuffer under the hood.)

Web19 Nov 2012 · Tone detection It’s certainly possible to use the FFT to detect the presence of a single sinusoidal tone in a time-domain sequence x(n). For example, if we wanted to detect a 30 kHz tone in a time-domain sequence whose sample rate was f s = 128 kHz, we could start by performing a 64-point FFT as shown in Figure 13–41. Then we would examine the … Web15 Feb 2024 · The technique for fusing permutations is more generally applicable beyond the FFT. Datapath for the permutation block in Fig. 1(d).
