These are complementary to the two initialization methods. releaseR-

Buffer_ object will be released in the destructor, so releaseResources()

is empty:

void DelayAudioProcessor::releaseResources()

{

// When playback stops, you can use this as an opportunity

// to free up any spare memory, etc.

// The delay buffer will stay in memory until the effect is

// unloaded.

}

The destructor runs once when the plug- in is removed by the host environ ...
