Hybrid Test Tone for Space-Averaged Room Audio Calibration Using A Moving Microphone

摘要

An example implementation may involve a network device detecting within a playback environment, via a microphone, an audio signal over a duration of time. After the duration of time, the implementation further involves the network device determining a frequency response of the playback environment based on the detected audio signal and a test tone. The test tone includes (i) a first component that includes noise at frequencies between a minimum of a calibration frequency range and a first threshold frequency, and (ii) a second component that sweeps through frequencies between a second threshold frequency and a maximum of the calibration frequency range.
