public EchoFilter(int numDelaySamples, float decay)
The number of delay samples specifies how long before the echo is initially heard. For a 1 second echo with mono, 44100Hz sound, use 44100 delay samples.
The decay value is how much the echo has decayed from the source. A decay value of .5 means the echo heard is half as loud as the source.
