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>\n- 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>\n- 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>\n- 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>\n- 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>\n- 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>\n- 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>\n- 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>"},{"id":"context","title":"Context and limits","body":"Author's design map for mobile games and interactive applications. 144 techniques in 18 groups, including basic signals, rules and combinations.
