Audioparam tests seem to have lots of failures with the specific values

[Manishearth]

Many of the AudioParam test results problems like these in the tests that ensure that the waveforms match:

[X Max error for test 87 at offset 116423 is not less than or equal to 0.000001865. Got 0.039968519116250927.]

It seems like something is being offset or perhaps the values are just completely wrong. Servo and Firefox do sound the same with the same AudioParam JS though.

We should compare the actual waveforms and see what's going on. We've had offset issues before so I wouldn't be surprised if a small offset was being introduced somehow.
