Audio gain: inputs, results and limitations
Adjust gain before exporting a new WAV, checking the result for clipping.
How to use Audio gain
- Choose the appropriate input file. General limits are 30 MB per file and 100 MB total.
- Review the options before running: Gain multiplier: 1.5
- Inspect the preview or result, then download a new file.
An illustrative use case
A quiet recording amplified with a gain multiplier of 1.5.
Select a real sample file you are allowed to process. Begin with a short, simple input before attempting a complex document or recording.
What to inspect in the output
Listen for clipping in the loudest passage. More gain can push peaks outside the PCM range, so a larger multiplier does not necessarily improve intelligibility.
Where this tool stops
Gain is clipped to the PCM range; loud inputs can distort.
