// When changing multiple audio object settings that must update at
// the same time, these functions allow the audio library interrupt
// to be disabled. For example, you may wish to begin playing a note
// in response to reading an analog sensor. If you have "velocity"
// information, you might start the sample playing and also adjust
// the gain of a mixer channel. Use AudioNoInterrupts() first, then
// make both changes to the 2 separate objects. Then allow the audio
// library to update with AudioInterrupts(). Both changes will happen
// at the same time, because AudioNoInterrupts() prevents any updates
// while you make changes.
