pyrilla
pyrilla is a self-contained statically linked binding to
gorilla-audio library -
“an attempt to make a free, straightforward, cross-platform, high-level
software audio mixer that supports playback of both static and streaming
sounds”. Like the original it is intended for video game development.
pyrilla’s goal is to provide a python audio package that can be
installed without any external dependencies with single
pip install pyrilla command. It is built with cython and its API is
inspired by part of great but unmantained
bacon game engine.
It works without any problems on OS X, Windows, and Linux. Officially
supported Python versions are py27, py33, py34, py35.


pyrilla on PyPI and supported systems

Pyrilla is wrapper on Gorilla Audio C library that is statically linked
during installation. For developers convenience it is distributed on
PyPI as binary wheels for Windows, OS X, and Linux. Its extensive built
pipeline targets different system flavours (32/64bit) and different
Python versions. On supported systems it can be easily instaled with
pip:
pip install pyrilla
Most up-to-date list of provided distributions is available on pyrilla’s
project page on PyPI.
Depending on target platform the underlying Gorilla Audio library is
compiled with slightly different settings:


Target platform
Available Python versions
Audio backend
Arch



Windows
py27, py33, py34, py35
XAudio2
Win32/Win64

Mac OS X
py27, py33, py34, py35
OpenAL
intel/x86_64

Linux
py27, py33, py34, py35
OpenAL
x86_64/i686 (32bit)



If you really need support for other platform or more Python versions
then fill issue on GitHub repository for this project so I can
prioritize my work. I don’t want to spend my time on providing more
distributions not knowing if anyone really needs them.
Note: Linux wheels for pyrilla on PyPI are portable Linux build
distributions (i.e. manylinux1) as described by PEP
513.
Source distribution (sdist) for pyrilla available on PyPI is still a bit
broken. Generally it is not supposed to compile on Linux. This is going
to change in future. If you want to use pyrilla on Linux you need to
build it by yourself on your platform. The process is preety
straightforward and described in building section of this README.
Last but not least, there is also some support for cygwin. Unfortunately
there is no binary wheel on PyPI for this environment yet. If you want
to use pyrilla under cygwin then you need to compile it manually.


usage
The easiest way to play single sound is to use Sound class:
from pyrilla import core

def finished(sound):
print("sound %s finished playing" % sound)
quit()


# note: sound file extension must be explicitely provided
sound = core.Sound("soundfile.ogg", "ogg")
# optional callback will be called when sound finishes to play
sound.play(finished)

while True:
# update internal state of default audio manager and mixer
# this mixes all currently played sounds, pushes buffers etc.
core.update()
To play looped audio you need to use Voice instance that can be
created from existing sound.
from pyrilla import core

sound = core.Sound("soundfile.ogg", "ogg")
voice = core.Voice(sound, loop=True)
voice.play()

while True:
core.update()
For more features like custom managers/mixers, voice control (pitch,
gain, pan) or stop/play see code samples in examples directory of
this repo.


building
Building pyrilla prerequisites:

cython
cmake
make

If you are going to build this package then remeber that Gorilla Audio
is bundled with this repository as Git submodule from my unofficial fork
on GitHub (under gorilla-audio directory). You need to eaither clone
this repository with --recursive Git flag or init submodules
manually:
git submodule update --init --recursive
Use cmake to build build gorilla-audio
cmake gorilla-audio/build
cmake --build . --config Release
python setup.py build
For Windows (also on cygwin):
cmake -DENABLE_OPENAL:STRING=0 -DENABLE_XAUDIO2:STRING=1 -DENABLE_DIRECTSOUND:STRING=0 .
cmake --config Release --build .
Then build and install the python extension:
python setup.py build
python setup.py install
Note that building for Windows may be bit trickier. If your personal
environment is broken and compilation step for Gorilla Audio does not
find the correct path for DirectX SDK and/or XAudio2 lib file. If you
have same problems as I have then you probably need to provide this path
manually to first cmake call:
-DDIRECTX_XAUDIO2_LIBRARY=path/to/the/DirectXSdk/Lib/x86/xapobase.lib
