Introduction

This package is the Python version of spAudio library providing spaudio module which enables fullduplex audio device I/O and spplugin module which enables plugin-based file I/O supporting many sound formats including WAV, AIFF, MP3, Ogg Vorbis, FLAC, ALAC, raw, and more. The spplugin module also supports 24/32-bit sample size used in high-resolution audio files, so you can easily load data with 24/32-bit sample size into NumPy’s ndarray.

Installation

You can use pip command to install the binary package:

pip install spaudio

If you use Anaconda or Miniconda , conda command with “bannohideki” channel can be used:

conda install -c bannohideki spaudio

NumPy package is needed only if you want to use NumPy arrays. If you don’t use NumPy arrays, no external package is required. Note that this package doesn’t support Python 2.

The linux version also requires spPlugin installation (audio device I/O requires the pulsesimple plugin based on PulseAudio ). You can install it by using dpkg (Ubuntu) or rpm (CentOS) command with one of the following packages.

If you want to use apt (Ubuntu) or yum (CentOS), see this page (for Ubuntu) or this page (for CentOS) .
