Interface: NoiseProfile

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:18

Represents the acoustic profile of the environment. This profile is used by other audio components (like VAD) to adjust their sensitivity.

Properties​

baselineRMS​

baselineRMS: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:20

Root Mean Square of the baseline ambient noise, calculated using a percentile.

confidenceScore​

confidenceScore: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:33

Confidence in the profile (0-1), based on data quantity and stability.

environmentType​

environmentType: "quiet" | "normal" | "noisy" | "very_noisy"

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:31

Classified type of the acoustic environment.

framesAnalyzedCount​

framesAnalyzedCount: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:41

Number of audio frames/buffers analyzed to generate or update this profile.

frequencyProfile?​

optional frequencyProfile: Float32Array

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:29

Optional frequency spectrum analysis (e.g., 32 bands). Populated if enableFrequencyAnalysis is true.

noiseStdDev​

noiseStdDev: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:24

Standard deviation of RMS values, indicating noise floor stability.

peakRMS​

peakRMS: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:22

Peak Root Mean Square detected during an observation window.

suggestedSilenceThreshold​

suggestedSilenceThreshold: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:39

Suggested silence detection threshold (RMS value) based on this profile.

suggestedSpeechThreshold​

suggestedSpeechThreshold: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:37

Suggested speech detection threshold (RMS value) based on this profile.

timestamp​

timestamp: number

Defined in: packages/agentos/src/core/audio/EnvironmentalCalibrator.ts:35

Timestamp (Unix epoch ms) of when this profile was last calculated.
