Sounddevice
Installation
The sounddevice backend is part of the optional dependency group sounddevice-backend. Either install it or install the required libraries manually.
pip install PySoundSphere[sounddevice-backend]
pip install PySoundSphere sounddevice soundfile numpy
Usage
After that you can use the backend like in the following.
import PySoundSphere
player = PySoundSphere.AudioPlayer("sounddevice")
Backend specific options
The following sections will cover all backend specific options available in the sounddevice backend.
blocksize
The sounddevice_blocksize parameter is the size of the buffer the audio stream uses.
The default value sounddevice_blocksize=0 is special, as it will use a (possibly varying) buffer size based on requirements of the host system.
On some systems and configurations the default value may cause issues. For example, there have been issues with stuttering audio when the playback was started while other applications were already using the audio device. This can often be fixed by increasing the blocksize.
Additional information:
import PySoundSphere
player = PySoundSphere.AudioPlayer("sounddevice", sounddevice_blocksize=1024)
| Small Blocksize | Larger Blocksize |
