calibrate

calibrate(audioStream): Promise<NoiseProfile>
Performs initial environment calibration using a MediaStream. Sets up a temporary Web Audio pipeline to analyze the stream.
Parameters
- audioStream: MediaStream
  The live audio input stream for calibration.
Returns Promise<NoiseProfile>
A promise that resolves with the initial noise profile, or rejects if calibration fails.
