Real-time Audio time-scale and pitch modification.
Real-time Audio time-scale and pitch modification Python library.
Aupyom is the pure-python library designed to allow for quick and easy sounds mixing. It has been designed to let you shift the pitch and change the time-scale of sounds in real time.
As aupyom API is really simple, you only need to know a few methods to start playing, the documentation is given as few demonstration notebooks:
- [Playing and mixing multiple sounds](./examples/Playingandmixingmultiplesounds.ipynb)
- [Live modification of the pitch and time-scale of sounds](./examples/Livemodificationofthepitchandtime-scaleofsounds.ipynb)
The last stable release is available on PyPI. It can be install via:
`bash pip install aupyom `
You can also install it from source: `bash python setup.py install `
Aupyom works with Python >= 2.7 and Python>=3.4.
Aupyom requires different libraries: * [numpy](http://www.numpy.org): for the low-level sound processing * [librosa](https://github.com/bmcfee/librosa): for higher-level sound processing and IO * [sounddevice](http://python-sounddevice.readthedocs.org/): a python bindings for the [PortAudio](http://www.portaudio.com) library - used to play sounds
# Integration with Poppy robots
Aupyom has been originally designed in the context of the [Poppy-project](https://www.poppy-project.org) aiming at developing open-source and easy-to-use robots. They are notably used in educational context for teaching computer science and discover IoT and robotics.
[Dedicated demonstration notebooks]() have been designed showing how the movement of a robot can be used to lively modify sound pitch and time-scale!
Thanks to that, aupyom has also been connected to [Snap!](http://snap.berkeley.edu) a variant of the famous visual programming language allowing the design of interface for intuitively modifying and mixing of sounds.
