|
| +
|
| + <p>Test that looping an AudioBufferSource works correctly if the source is started and the
|
| + buffer is assigned later, but before the source would start. This can't be easily tested in an
|
| + offline context because we can't precisely control when the assignment of the buffer to the
|
| + source is done.</p>
|
| +
|
| + <p>Press the "Start" button for the normal case where the buffer is assigned before start.</p>
|
| +
|
| + <p>Press the "Start delayed" button for the case where the source is started and the buffer
|
| + assigned later.</p>
|
| +
|
| + <p>You should hear audio about 2 sec after pressing the button. It should continue until you
|
| + press the corresponding Stop button.</p>
