dB converter - Ubetoo

Tool

Run the tool

Add your inputs below and Ubetoo will return the result, output, or generated file in the result panel.

-6 dB to gain +3 dB to power 2x gain to dB 4x power to dB

Result

6.02 dB

A linear gain of 2x equals 6.02 dB.

Decibels 6.02 dB

Input ratio 2x

Equivalent amplitude ratio 2x

Formula 20 * log10(linear gain)

How to use this tool well

Use amplitude mode for level/gain moves and power mode for energy or intensity comparisons.
The formulas differ, so keep an eye on whether the source system is speaking in gain or power terms.

Quick examples

-6 dB -> 0.501187x gain
2x linear gain -> 6.02 dB
-3 dB power -> 0.501187x ratio

Frequently asked questions

What is the db converter built for?

Switch between decibels, amplitude ratios, and power ratios when you are matching plugin values, automation curves, or loudness targets.

Should I upload files or use manual entry in the db converter?

The db converter is designed around a direct form workflow, so the fastest path is to fill in the required inputs and run it.

Which inputs matter most on the db converter page?

This page is driven mainly by uploads or imported files, so the important preparation is having the right source material ready.

What file types or import layouts does the db converter accept?

How do I get the best result from the db converter?

Use amplitude mode for level/gain moves and power mode for energy or intensity comparisons. The formulas differ, so keep an eye on whether the source system is speaking in gain or power terms. Typical use cases include -6 dB -> 0.501187x gain; 2x linear gain -> 6.02 dB.
