Abstract
Frequency response correction systems and methods for consumer electronic (CE) devices are disclosed. Applying one or more of disclosed techniques can improve a consumer's listening experience. The frequency response of a CE device can be corrected to remove or attenuate salient, undesirable features of with minimal user interaction. Audio quality can be tuned for optimal or near optimal performance even at maximum or near maximum volume levels substantially without fluctuations, clipping, or any other distortions. In some embodiments, audio response of the CE device can be captured, smoothed, and corrected. Correction parameters can be stored on the CE device.
Claims21
A method of correcting a frequency response of an electronic device, the method comprising:
- by a first electronic device comprising one or more processors:
- outputting a user interface for presentation to a user, the user interface configured to provide functionality for the user to generate a frequency response adjustment for a second electronic device;
- receiving, through the user interface, a selection from the user of a target smoothing level of a test audio signal;
- smoothing, in accordance with the target smoothing level, the test audio signal to attenuate one or more signal distortions;
- determining, based at least in part on the smoothed test audio signal, one or more frequency response correction parameters;
- and
- electronically transmitting the one or more frequency response correction parameters to the second electronic device to enable the second electronic device to apply the one or more frequency response correction parameters to a subsequent audio signal.
Non-transitory physical computer storage comprising executable instructions that, when executed by one or more processors, cause the one or more processors to implement operations for determining a frequency response correction for an electronic device, the operations comprising:
- outputting a user interface for presentation to a user, the user interface configured to provide functionality for the user to correct a frequency response of an electronic device;
- receiving, through the user interface, a selection from the user of a desired smoothing characteristic of an input audio signal;
- smoothing, in accordance with the desired smoothing characteristic, the input audio signal to attenuate one or more signal distortions;
- and
- determining, based at least in part on the smoothed input audio signal, one or more frequency response correction parameters to be applied by the electronic device.
An apparatus for correcting a frequency response of an electronic device, the apparatus comprising:
- one or more processors configured to:
- electronically generate a user interface for presentation to a user, the user interface comprising one or more user interface controls configured to enable the user to adjust a frequency response of an electronic device;
- receive, through the user interface, a selection from the user of a smoothing parameter for an input audio signal;
- smooth, in accordance with the smoothing parameter, the input audio signal to attenuate one or more signal distortions;
- and
- determine, based at least in part on the smoothed input audio signal, a frequency response correction parameter to be applied by the electronic device.
