|
| -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.
