chippy 0.1.0

What’s New

0.1.0 - First release! Everything should work fine, but bug reports or improvement

suggestions are most welcome. There isn’t any documentation yet, but the code should be pretty easy to understand.

1) Compatibility

Chippy is developed for Python 3. It will also work on Pypy3 and, being written in pure Python, should work on any compliant interpreter. Please let me know if you encounter any issues.

2) Installation

No installation is necessary. Chippy is a tiny library with no dependencies. Simply copy the chippy directory into the top level of your project folder, and import chippy.

If you prefer, Chippy is also available on PyPI for easy installation via pip.

3) Usage

Several types of waveforms are supported: sine, saw, triange, square, and FM. If you just want to make a byte string of raw PCM data, you can use the <waveform>_pcm(length=1) methods. There is another set of methods for producing standard RIFF format wave data, ready to play: <waveform>_riff(length=1). You can save this data to disk with the following methods: save_wave(pcm_data, filename) and save_raw_pcm(pcm_data, filename). Here is a quick example of usage:

import chippy

synth = chippy.Synthesizer(framerate=44100)

# Create a raw PCM Sine wave: sine_wave = synth.Sine(length=2, frequency=220) # Save it to disk with a RIFF wave header: synth.save_wave(sine_wave, “wavefile.wav”)

# Make an FM waveform with RIFF header: fm_wave = synth.FM(carrier=440, modulator=220)

MORE DOCUMENTATION TO COME!
