Example
const dsp = require('dsp-kit')
const forward = dsp.rfft(1024)
const result = forward(signal)Methods
(static) rfft(buffer)
Performs a forward transform on the sample buffer. Converts a time domain signal to frequency domain spectra.
Parameters:
| Name | Type | Description |
|---|---|---|
buffer |
Array | The sample buffer. Buffer Length must be power of 2 |
