Documentation

PyOgg

PyOgg provides bindings for Xiph.org's OGG Vorbis, OGG Opus and FLAC audio file formats.

It comes bundled with the required dynamic libraries (.dll) in the Windows WHEEL (.whl) distributions.

The required libraries include the OGG library (e.g. libogg.dll) and at least either OGG Opus' libraries (e.g. libopus.dll, libopusfile.dll) and / or OGG Vorbis' libraries (e.g. libvorbis.dll, libvorbisfile.dll) to support Opus and Vorbis respectively, or the FLAC C library (e.g. libFLAC.dll) for FLAC support.

You can install PyOgg using PyPI.

pip install PyOgg

All the functions, structures and datatypes are the same as in the C++ implementation, except for some that couldn't be translated. If you want to use them natively you will have to use ctypes' data types. Please refer to the official documentation and the C++ headers.

You can import the various functions from pyogg.ogg, pyogg.vorbis, pyogg.opus and pyogg.flac or use the predefined classes and functions from pyogg.

PyOgg is not capable of playing files, however, you can use OpenAL for normal or even 3D playback with PyOpenAL.

Here's a reference for PyOgg's own classes and functions:

<class> pyogg.VorbisFile(path)
	# opens and reads an OGG Vorbis file to a buffer. 
		<str> path # path to the file (can be relative or absolute)
	
	<int> VorbisFile.channels
		# how many audio channels the audio data has (1 = mono, 2 = stereo, etc.)
	
	<int> VorbisFile.frequency
		# audio frequency (e.g. 48000, 44100, etc.)
		
	<str or bytes> VorbisFile.buffer
		# audio data
		
	<int> VorbisFile.buffer_length
		# length of the buffer
