Audio example
|
||
|
|
=============
|
||
|
|
|
||
|
|
This example plays sounds of different formats. You should see a grid of
|
||
|
|
buttons labelled with filenames. Clicking on the buttons will play, or
|
||
|
|
restart, each sound. Not all sound formats will play on all platforms.
|
||
|
|
|
||
|
|
All the sounds are from the http://woolyss.com/chipmusic-samples.php
