Variable Documentation

FREQ_RES

float FREQ_RES = (float)SAMPLE_RATE / (float)WINDOW_SIZE_OVERLAP

constexpr

Frequency range of an FFT bin in Hz.

The resolution is the frequency range, in Hz, represented by each output bin of the Fast Fourier Transform.

Ex: 8192 Samples/Second / 256 Samples/Window = 32 Hz per output bin.

FREQ_WIDTH

float FREQ_WIDTH = 1.0 / FREQ_RES

constexpr

Duration of a window, in seconds.

The width is the duration of time represented by a single window's worth of samples. Ex: 256 Samples/Window / 8192 Samples/Second = 0.03125 Seconds/Window.

WINDOW_SIZE_BY_2

int WINDOW_SIZE_BY_2 = WINDOW_SIZE_OVERLAP >> 1

constexpr

WINDOW_SIZE_OVERLAP

uint16_t WINDOW_SIZE_OVERLAP = WINDOW_SIZE << WINDOW_OVERLAP

constexpr
