signalGenerator

Generates different test signals such as noises, waveforms and sweep tones:

  • sine
  • triangle
  • sawtooth
  • square
  • white_noise
  • MLS
  • delta
  • pulse
  • level
  • lin_ramp
  • log_ramp
  • log_sweep
  • inverse_log_filter
  • lin_sweep
  • inverse_lin_filter

It also generates train of any kind of signal.

Installation

For the latest releases install from the GitHub repo

pip install git+https://github.com/xaviliz/signalGenerator

Usage

Generate a sine wave

import signal_generator as sg

signal_generator = sg.SignalGenerator("sine", 20)
sine_20_seg = signal_generator()

Generate a train of sine waves

signal_generator = sg.SignalGenerator("sine", 1, nCycles=10)
sine_train = signal_generator()

Generate a linear ramp

amplitude = 1
duration = 10
sample_rate = 44100
signal_type = "lin_ramp"
fade_in = 0.0
fade_out = 0.0
logger = sg.getLogger(level="DEBUG")

# synthesize signal
signal_generator = sg.SignalGenerator(
    signal_type,
    duration,
    amplitude=amplitude,
    sampleRate=sample_rate,
    logger=logger,
    fadeIn=fade_in,
    fadeOut=fade_out,
)
testSignal = signal_generator()
