The WebAudio spec has updated the limits for the frequency, detune, and gain AudioParam attributes for a BiquadFilterNode. Previously these allowed any floating-point value.


This makes the limits a more explicit because the larger values would generally either clamp to some limit or cause the output to produce infinities or NaN. Now, the values will be clamped to the limits so these things will not happen.
