How It Works
This tool adjusts the amplitude (volume) of your audio file. It uses the Web Audio API to process the audio entirely within your browser. When you upload a file and set a volume level, the tool applies a "gain" node to the audio signal. A volume of 100% is the original volume, 200% doubles the volume, and 50% halves it. After processing, you can listen to the result and download the modified audio as a WAV file.
