-Tests that an audio-rate signal (AudioNode output) can be connected to an AudioParam.
-Specifically, this tests that an audio-rate signal coming from an AudioBufferSourceNode
-playing an AudioBuffer containing a specific curve can be connected to an AudioGainNode's
-.gain attribute (an AudioParam). Another AudioBufferSourceNode will be the audio source
-having its gain changed. We load this one with an AudioBuffer containing a constant value of 1.
-Thus it's easy to check that the resultant signal should be equal to the gain-scaling curve.
