Generate WAVE files
Project description
This project lives at GitHub.
Installation
You need Python 3. I don’t want to support Python 2 for now. This is a pure Python package with no other dependencies.
I recommend you install the latest version from PyPI with pip:
pip install wavemaker
The standard distutils installation works too:
tar xzf wavemaker-*.tar.gz cd wavemaker-* python setup.py install
Usage
The command line tool is called make_wave. This is how you use it:
make_wave sine-wave.wav
There is more help built in:
$ make_wave --help usage: make_wave [-h] [--waveform {sine}] [--frequency FREQUENCY] [--amplitude AMPLITUDE] [--duration DURATION] [--sample_rate SAMPLE_RATE] [--sample_size {16}] output_path Generate WAVE files. positional arguments: output_path The path to the resulting WAVE file optional arguments: -h, --help show this help message and exit --waveform {sine} The shape of the signal being generated (default: sine) --frequency FREQUENCY The oscillating rate of the wave. A non-negative float, in Hz (default: 440.0) --amplitude AMPLITUDE The amplitude of the wave. A float between 0.0 and 1.0 (default: 1.0) --duration DURATION The time duration of the signal. A non-negative float, in seconds (default: 1.0) --sample_rate SAMPLE_RATE The number of samples per second. A non-negative int, in Hz (default: 44100) --sample_size {16} The number of bits used to store each sample (default: 16)
API
There is a single public API function call. It takes the same arguments that the command line tool does as keyword arguments. Please see the docstring for more:
write_wave_file(output_path, waveform='sine', frequency=440.0, amplitude=1.0, duration=1.0, sample_rate=44100, sample_size=16)
Basic usage:
import wavemaker wavemaker.write_wave_file('sine-wave.wav')
