This library generates simple waveforms that can be used to generate different type of audio signals.

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-waveform

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-waveform

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-waveform

This example generates one wavelength of a 440hz sine wave when played at 16 kilosamples per second:

from adafruit_waveform import sine
wave = sine.sine_wave(16000, 440)

API documentation for this library can be found on Read the Docs.
