Preliminary (unfinished) interface to audio device. |
| 593 | 130 |
Currently works with LINUXs or SUNs /dev/audio driver and |
| 592 | 131 |
IRIX (indy). |
| 593 | 132 |
On iris, the default setup is for 8 bit mono |
| 28 | 133 |
so I can play the standard sound files I have here. |
134 |
It needs much more work, for stereo, different sampling rates etc. |
|
135 |
||
| 592 | 136 |
This is an experimental class - its interface & implementation |
137 |
may change in the future. |
