SigLyser

SigLyser is a Python library for analysing vibration signals from rotating machinery. It provides frequency-domain transformations and statistical measures built on NumPy and SciPy.

Features

• FFT — single-sided amplitude spectrum from time-domain data
• 3D FFT — speed-frequency amplitude map (waterfall) segmented by engine cycle
• RMS & Amplitude — root mean square and peak-to-peak amplitude per cycle vs speed

Quick example

import numpy as np
from siglyser import calc_fft

t = np.linspace(0, 1, 1000)
signal = np.sin(2 * np.pi * 50 * t)

freq, amp = calc_fft(t, signal)

Installation

pip install siglyser
