Use Dynamic Range Control to adjust the shaping of the dynamics in your audio.
To use dynamic range compression on audio, do this:
1. | Select the media file in the library that you want to use dynamic range compression on. |
2. | If required, use range selection to select the portion of audio you want to apply the effect to. See Range Selection for more information on selecting a range of an audio file. If you don't select a range, the effect is applied to the entire audio clip. |

|
Note: the entire audio file's waveform is selected by default when this feature is opened. If you want to apply this feature to the entire audio file, you do not need to use range selection when the entire waveform is selected.
|
3. | Decide whether you want to apply the effect on all the available channels, or just one channel. See Selecting Channels for Editing for more information on selecting channels. |
4. | Click Dynamic Range Control under the Apply Effect section. |
5. | Use the Output Gain slider to adjust the output gain for the processed file to make up for a decrease in the audio's volume. |
6. | Use the control sliders as follows: |
• | Limiter: adjust these sliders to aggressively limit high level signals. You can use the limiter to prevent clipping or distortion. |
• | Compressor: use these sliders to apply more gentle dynamic control to medium level signals and peaks. |
• | Gate/Expander: use these sliders to boost (expand) the level of soft signals. Note that the expander can have a ratio greater or less than 1.0. When the ratio is greater than 1, it is operating as a gate and any signals below the threshold will be decreased in volume. |
7. | If required, you can preview how the applied effect will sound by selecting Adjusted result and then clicking the Preview button. Select Original audio if you want to preview the original audio. |
8. | Click Apply to apply the dynamic range control. |

|
Note: if required, click on the Effect tab to see the applied effect in the edit panel. See Effect Tab for more information.

Common Dynamic Range Controls
When using the Dynamic Range Control sliders, adjusting these common control sliders will have the resulting effects:
• | Threshold: use to set the point where the dynamics processing takes place. |
• | Ratio: use to set the ratio for its respective dynamics section. Higher ratios will result in more extreme compression, limiting or expansion. |
• | Attack: use to set how quickly the compressor, limiter or expander/gate reacts (in milliseconds) to an incoming signal when the signal passes the specified threshold. |
• | Release: use to set how quickly the module stops applying compression, limiting or expansion/gating when the signal falls below the threshold. |
