@class wxSound
|
|
|
|
This class represents a short sound (loaded from Windows WAV file), that
|
|
can be stored in memory and played.
|
|
|
|
Currently this class is implemented on Windows and Unix and can use either
|
|
Open Sound System (OSS) or Simple DirectMedia Layer (SDL) under the latter.
|
|
Notice that OSS is not provided any more by most, and maybe even all,
|
|
Linux systems in 2017 and osspd (OSS Proxy Daemon) package typically needs
|
|
to be installed to make it work.
