4 This module wraps the aubio library for Python using the numpy module.
6 Using the Python aubio module
7 -----------------------------
9 After installing python-aubio, you will be able to import the aubio module:
14 >>> help(aubio.miditofreq)
16 Finding some inspiration
17 ------------------------
19 Some examples are available in the `python/demos` directory. These scripts are
20 small programs written in python and using python-aubio.
22 For instance, `demo_source.py` reads a media file.
24 $ ./python/demos/demo_source.py /path/to/sound/sample.wav
26 and `demo_timestretch_online.py` stretches the original file into a new one:
28 $ ./python/demo/demo_timestretch_online.py loop.wav stretched_loop.wav 0.92`
30 Note: you might need to install additional modules to run some of the demos.
31 Some demos use [matplotlib](http://matplotlib.org/) to draw plots, others use
32 [PySoundCard](https://github.com/bastibe/PySoundCard) to play and record
35 Testing the Python module
36 -------------------------
38 To run the all the python tests, use the script:
40 $ ./python/tests/run_all_tests
42 Each test script can also be called one at a time. For instance:
44 $ ./python/tests/test_note2midi.py -v
46 Install in a virtualenv
47 -----------------------
49 You should be able to install python-aubio directly from the top source
52 First, create a virtualenv to hold the required python module:
55 $ source pyaubio/bin/activate
57 Now install and build the python extension using:
64 Before compiling this module, you must have compiled libaubio.
66 A simple way to do this is with pip:
68 $ pip install -r requirements.txt
70 For more information about how this module works, please refer to the [Python/C
71 API Reference Manual] (http://docs.python.org/c-api/index.html) and the
72 [Numpy/C API Reference](http://docs.scipy.org/doc/numpy/reference/c-api.html).
74 Compiling python aubio
75 ----------------------
77 To build the aubio Python module, run the following command from the top source
82 Note: if libaubio was previously built using waf, the script will use it.
83 Otherwise, the entire library will be built inside the python extension.

96 Alternatively, you may want to use the Python module without installing it by
97 setting your PYTHONPATH, for instance as follows:
99 $ export PYTHONPATH=$PYTHONPATH:$PWD/`ls -rtd build/lib.* | head -1`:$PWD/tests
