NAME

sound_data - container class for sound data

DESCRIPTION

The sound data class is a container class to hold sound data. It does not playback sound data, that function is performed by the sound class. Currently, the only manner to place data into the sound data class is by reading a sound file. Sound files are read using the sound reader class, but there is a direct interface through the sound data class such that the user does not need to deal directly with the sound reader class.

Because sound files are device specific, the LYMB_SOUND environmental variable needs to be set to tell LYMB which sound reader to interface to. For Sun Microsystems SparcStations, set LYMB_SOUND to sun_sound. For Silicon Graphics Indigo systems, set LYMB_SOUND to sgi_sound.

There is an environmental variable, LYMB_SOUND_PATH, which may be set to the directories that contain sound files to eliminate the need to input full path names of files. The use of LYMB_SOUND_PATH for sound files is analogous to LYMB_PATH for script files.

SUPERCLASS

object

INSTANCE VARIABLES

There are currently no user accessable instance variables. The sound data class is curremtly meant to be accessed through other classes which act as reader and filter classes.

MESSAGES

read_file= Input the name of a file and read that file into the sound data instance.
