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()

Dependencies

• Numpy
• Scipy
• Matplotlib
