Description

The function load-sound converts source into a loaded sound which can be played by play-sound.

source can be a pathname designator or an array returned by read-sound-file.

owner should be a CAPI interface object, or nil which means that the sound's owner is the current top level interface.

The loaded sound sound will be unloaded (freed) automatically when its owner is destroyed. To create a sound that is never unloaded, pass the screen as the argument owner.

Notes

1. The array sound contains the contents of the file. Its bytes are interpreted by the OS functions, so the format can be whatever they can deal with, for example WAV on Microsoft Windows. The fact that this date is represented as an (unsigned-byte 8) array in Lisp does not constrain the output size.
2. load-sound is not implemented on GTK+ and Motif.
