WebFeb 20, 2010 · The more samples you transform at a time (a power of two), the higher the resolution of the spectrum. The highest detectable frequency is half the sample frequency used. Example: sample rate = 48000Hz (=48 samples per millisecond/channel) max frequency = 24000Hz. If you now use an FFT with 512 samples, you receive 256 useful … inhealth annual report
