Properties

Name	Type	Description
enabled	boolean	Whether Fourier denoising is enabled. Note that this is experimental and may not work as expected.
mediaDetectionEnabled	boolean	Whether automatic media detection is enabled. When enabled, the filter will automatically detect consistent background TV/music/radio and switch to more aggressive filtering settings. Only applies whe
staticThreshold	number	Static threshold in dB used as fallback when no baseline is established.
baselineOffsetDb	number	How far below the rolling baseline to filter audio, in dB. Lower values (e.g., -10) are more aggressive, higher values (e.g., -20) are more conservative.
windowSizeMs	number	Rolling window size in milliseconds for calculating the audio baseline. Larger windows adapt more slowly but are more stable.
baselinePercentile	number	Percentile to use for baseline calculation (1-99). Higher percentiles (e.g., 85) focus on louder speech, lower percentiles (e.g., 50) include quieter speech.
