 * NOTE FOR WINDOZE USERS: Given inherent delays in the sound
 * output mechanism under Windoze, there is a trade-off between
 * smoothness of fast SKINI parameter updates and input/output
 * latency as discussed above.  You can use buffer sizes as low
 * as 100 (maybe lower) for delay critical applications, but in
 * this case SKINI parameter updates will be clumped together
 * and sound unnatural.  If you want smoother parameter updates
 * and you can live with more delay, try using buffer sizes
 * closer to 1000.  If you need smooth parameter updates AND
 * low delay, don't use Windoze!
