System and method for detecting and indicating that an audio system is ineffectively tuned

Abstract:

A digital audio system, which may be an integrated audio system of a vehicle, includes a microphone, a loudspeaker, and a processor. The processor is operable to modify digital audio signals based on tuning parameters to compensate for acoustic characteristics of the environment. The processor is further operable to detect that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment. The detection is based on an audio signal corresponding to audio captured from the environment and/or on the values of the tuning parameters. Upon detecting that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment, an indication is provided that the audio system should be calibrated to adjust the tuning parameters to the environment. Related methods and computer-readable media are also disclosed.
