An app accounts for background noise and isolates useful sound. A scenario can use the environment to adjust thresholds, audibility or processing.

1. The parameter controls background-noise reduction

- Keep the original recording for comparison with processing.

## How it works

The background becomes an input to the rules rather than just a nuisance. The sources and causes of noise cannot always be determined.

## Variants

### Variants and applications

<a id="family-ambience-variants"></a>

- Noise as a resource. Signal: Overall relative ambient level. Application: City noise charges the station, and a quiet room slows it down. Access level: Signal analysis. <a id="variant-mic-089"></a>
- Noise is like danger. Alarm: Adaptive threshold exceeded. Application: Real sounds increase the anxiety of opponents in horror. Access level: Signal analysis. <a id="variant-mic-090"></a>
- Quiet windows. Signal: Sections with low background level. Application: Allow action only in moments of acoustic calm. Access level: Signal analysis. <a id="variant-mic-091"></a>
- Change the background. Signal: The difference between current signs and previous ones. Application: Rebuild the weather or biome when the sound environment changes. Access level: Recognition. <a id="variant-mic-092"></a>
- Type of sound environment. Signal: A set of likely categories. Application: Offer various gaming content in noisy or quiet environments. Access level: Recognition. <a id="variant-mic-093"></a>
- Voice to background ratio. Signal: Speech intelligibility assessment. Application: Give the task of speaking clearly against a background of interference. Access level: Recognition. <a id="variant-mic-094"></a>
- Masking the game signal. Signal: The audibility of the target sound among noise. Application: Search for a beacon that is hidden in real noise. Access level: Recognition. <a id="variant-mic-095"></a>
- Acoustic fingerprint of the session. Signal: Spectrum and event statistics over time. Application: Generate a palette, creatures or music from the sounds of a specific session. Access level: Recognition. <a id="variant-mic-096"></a>
