Overview

Dialogue De-reverb allows for efficient and clean reduction of unwanted reverb in dialogue recordings. Unlike the all-purpose De-reverb module, Dialogue De-reverb does not require learning a reverb profile from the input audio before processing. Instead, it leverages a machine-learning algorithm that has been trained to identify and separate reverberant components from dialogue components in an input signal. After separating the dialogue and reverb components, the reverb signal level can be independently adjusted without reducing the dialogue signal level.

Controls

The following section describes the controls available for reducing the separated reverb level, refining the reverb detection sensitivity, adjusting the amount of background noise to maintain, and determining the separation algorithm behavior.

Reduction

Adjusts the amount of negative gain (in dB) applied to the separated reverb component signal.

Sensitivity

Determines how much of the input signal will be identified as reverb by the separation algorithm.

  • Lower values will instruct the separation algorithm to narrowly define what it categorizes as reverb in the input signal. This can result in the presence of reverberant content in the rendered signal, but can help to maintain dialogue clarity.
  • Higher values will instruct the separation algorithm to broadly define what it categorizes as reverb in the input signal. This can result in more significant reverb reduction, at the cost of introducing artifacts and reducing dialogue clarity.

Ambience Preservation

Adjusts the amount of desired background noise to be retained in the processed output. The separation algorithm may include background noise in the separated reverb signal component, resulting in the unwanted reduction of unrelated background noise.

  • Lower values allow for broader detection and separation of reverb against other background noise in the input signal. This may result in unwanted reduction of background noise when reducing the reverb component level.
  • Higher values allow for stricter detection and separation of reverb against other background noise in the input signal. This can result in less background noise being included in the separated reverb component, but may result in unwanted reverberant content being identified as background noise.

Separation Algorithm

The following separation algorithm modes are available in the Dialogue De-reverb module.

Channel Independent

When this mode is selected, the separation algorithm is applied to the input audio channels independently. Channel independent mode is the fastest Separation algorithm option. It offers the most efficient real-time preview performance and processing speeds when working with the Dialogue De-reverb module in the RX Audio Editor.

Joint Channel

When this mode is selected, joint channel processing is applied to the input audio before determining the separation between dialogue and reverb signal components. Joint Channel mode offers higher quality separation results than Channel Independent mode, especially when processing stereo files with similar content on both channels (correlated signals, strong stereo image).

Advanced Joint Channel

When this mode is selected, joint channel and additional advanced processing is applied to the input audio before determining separation between dialogue and reverb. Advanced Joint Channel mode offers the highest quality separation results, especially when processing files with high sampling rates. This mode requires longer processing times than the other two modes. If processing time is a concern, Channel Independent mode can be used as a faster, lower quality alternative.

Preview Functionality

Reduced Quality Preview Mode

Unlike many of the modules with preview capabilities in the RX 8 Audio Editor, Dialogue De-reverb utilizes a reduced quality preview mode. Follow this link to learn more about Reduced Quality Preview Mode.

Alternative Modules

For more generalized, non-dialogue specific reverb reduction, try using the De-reverb module.
