Using Equal-Power Stereo Pan Calculator
Calculate ideal left and right gains for a mono source.
- Enter pan position, source gain using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Pan position: 0 minus 1 left to plus 1 right Source gain: 1 linear amplitude Left gain: 0.70710678 Right gain: 0.70710678 Sum of squared gains: 1
Questions & answers
What does Equal-Power Stereo Pan Calculator calculate?
Calculate ideal left and right gains for a mono source.
Which units should I enter?
Pan position uses minus 1 left to plus 1 right. Source gain uses linear amplitude. Convert values to these units before calculating.
Which formula does it use?
Angle = (pan+1)π/4; left = cos(angle), right = sin(angle).
What does the included example show?
Pan position: 0 minus 1 left to plus 1 right; Source gain: 1 linear amplitude. Result: Left gain = 0.70710678; Right gain = 0.70710678; Sum of squared gains = 1.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
