rmath.signal

FFT-based signal processing powered by RustFFT. O(N log N) transforms and convolution.

fft_example.py

import rmath.signal as rs
import rmath.vector as rv

signal = rv.Vector.linspace(0, 6.28, 1024).sin()
spectrum = rs.fft(signal)
magnitudes = spectrum.to_mags()

API Reference

Function	Returns	Description
`fft(signal)`	ComplexVector	Forward FFT. Accepts Vector or list[float].
`ifft(cv)`	Vector	Inverse FFT from ComplexVector back to real signal.
`fft_styled(signal)`	(mags, phases)	FFT returning magnitude and phase vectors directly.
`rfft(signal)`	Vector	Real-valued FFT (magnitude spectrum only).
`convolve(signal, kernel, mode)`	Vector	Convolution. `mode`: `"full"` (default), `"same"`, or `"valid"`.
