This command boosts or attenuates audio, i.e. makes it louder or quieter. If a selection exists, only the selection is amplified, otherwise the entire document is amplified. The command displays the Amplify dialog, which lets you specify the desired gain in decibels. Enter a positive gain for boost, or a negative gain for attenuation. To see what the new peak level would be, press the Tab key. To do the amplify, click OK or press Enter. If you're boosting enough so that the audio would be clipped, an orange CLIP indicator appears, and a warning message is displayed.
