Adjusting Volume
Every audio sample is multiplied by your chosen factor: 0.5× halves the amplitude, 2× doubles it. Values above 1× can push peaks past the maximum, which is clipped and may sound distorted, so raise volume gradually.
The adjusted audio is exported as a WAV file. Everything runs in your browser.
