NAOqi Audio - Overview | API

What it does

ALAudioPlayer provides playback services for multiple audio file format and the associated common functionalities (play, pause, stop, loop, etc...). The resulting audio stream is in all cases sent to NAO’s loudspeakers.


This module is only available on the robot.

How it works

ALAudioPlayer relies on several decoding Linux libraries (mainly Gstreamer and SNDFile) to efficiently decode and stream to audio outputs a good variety of audio file formats.

Performances and Limitations

Efficiency has been optimized to reach the lowest time of reaction when loading / starting a file but depending on the audio file format, that time can vary. For applications that requires very low loading / starting times, uncompressed WAV files should be preferred to any other compressed file format.

Getting started

The most straightforward way to start using ALAudioPlayer is to use the Play Sound box in Choregraphe (Audio boxes section).
