For example, if your audio has background noise, use the De - Noise plugins like Voice De - Noise or Spectral De - Noise. When working with dialogue, the Dialogue Isolate plugin can be very helpful. Make sure to update the software regularly to access the latest features and improvements. Store the software in a stable environment and avoid using it on systems with low resources as it may affect performance.
