Why is the applied boost smaller than the gain I selected?
The tool reduces the requested gain when there is not enough peak headroom. This prevents the adjustment from pushing the output above your ceiling. The result shows both the requested and applied gain.
Increase volume with the noise in mind
A gain increase raises speech, music, and existing noise together. If the recording is noisy, clean it first. Use a negative gain value to lower loud audio while preserving its timing, sample rate, and channel count.
