After a feature ships in Chrome, the values listed here are not guaranteed to be up to date.

  • No signal
  • No signal
  • Positive



There are no API changes, but moving from k-rate to a-rate automation will produce audible differences, generally for the better. There will very likely be a performance hit with this change, but only if the application is doing parameter automations for BiquadFilter nodes.
