How to use this tool

  1. Enter peak, gain, ceiling.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "peak": -6,
  "gain": 8,
  "ceiling": -1
}

Accuracy and scope

Sample peak arithmetic only; does not measure true peak, limiting, intersample overshoot or loudness.
