InitializeMatlabOpenAL([debuglevel] [,snddevicename] [, openal_c_style])
Call this function at the beginning of your experiment script if you intend
to use low-level OpenAL sound commands in your script as provided by our
Options: All options are optional.
debuglevel = 0 to 3: Setting debuglevel == 0 will disable debug-output.
A level of 1 will cause MOAL to output error messages and abort your
scripts execution if it detects any OpenAL error. A level of 2 provides
additional information that may help you to optimize your code. level 3
means to be very verbose
snddevicename: Optional. Request a specific sound output device by
its name. If left out, or if an invalid name is given, OpenAL will
select a default output device - the most capable and most efficient
device in your system.
openal_c_style = 0 / 1: Optional. If left out or set to zero, all
constants will be loaded in structs in order to avoid cluttering the
Matlab workspace too much. You’ll have to replace all AL_xxx calls by
AL.xxx calls, e.g., AL_TRUE becomes AL.TRUE .
If set to one, then all constants will additionally be provided in standard
C-Style syntax, aka AL_TRUE, but this only works in the main function, not
The ‘OpenAL for Matlab’ low level wrapper moal was implemented by Mario
Kleiner, trivially derived from our MOGL Matlab for OpenGL wrapper, which
was developed and contributed to Psychtoolbox under GPL license by
Prof. Richard F. Murray, University of York, Canada and Mario Kleiner.
MOAL is now licensed under the more permissive MIT license since 2011.
