User Created Sound Example
|
|
Copyright (c), Firelight Technologies Pty, Ltd 2004-2016.
|
|
|
|
This example shows how create a sound with data filled by the user.
|
|
It shows a user created static sample, followed by a user created stream.
|
|
The former allocates all memory needed for the sound and is played back as a static sample,
|
|
while the latter streams the data in chunks as it plays, using far less memory.
