Abstract
A method for dynamic equalization is performed at a system. The system receives an electronic audio signal. The system monitors available headroom based on two or more of: an amplifier of the system, a change in volume of the system, characteristics of a transducer of a loudspeaker associated with the system, and the audio signal. Responsive to a change in the available headroom, the system modifies one or more parameters of an equalizer to at least a portion of the signal in order to extend a physical low-frequency response of the loudspeaker, the one or more parameters comprising a gain for the and a frequency.
Claims20
A method for dynamic equalization performed at a system, the method comprising:
- receiving an electronic audio signal;
- monitoring available headroom based on two or more of:
- an amplifier of the system, a change in volume of the system, characteristics of a transducer of a loudspeaker associated with the system, and the audio signal;
- and
- responsive to a change in the available headroom, modifying, based on the change in the available headroom, one or more parameters of an equalizer to at least a portion of the signal in order to extend a physical low-frequency response of the loudspeaker, the one or more parameters comprising a gain.
A system comprising:
- circuitry;
- one or more processors;
- and
- memory storing one or more instructions for execution by the one or more processors, the one or more instructions causing the system to perform operations comprising:
- receiving an electronic audio signal;
- monitoring available headroom based on two or more of:
- an amplifier of the system, a change in volume of the system, characteristics of a transducer of a loudspeaker associated with the system, and the audio signal;
- and
- responsive to a change in the available headroom, modifying, based on the change in the available headroom, one or more parameters of an equalizer to at least a portion of the signal in order to extend a physical low-frequency response of the loudspeaker, the one or more parameters comprising a gain.
A non-transitory computer-readable storage medium storing one or more programs for execution by one or more processors of a system, the one or more programs comprising instructions for:
- receiving an electronic audio signal;
- monitoring available headroom based on two or more of:
- an amplifier of the system, a change in volume of the system, characteristics of a transducer of a loudspeaker associated with the system, and the audio signal;
- and
- responsive to a change in the available headroom, modifying, based on the change in the available headroom, one or more parameters of an equalizer to at least a portion of the signal in order to extend a physical low-frequency response of the loudspeaker, the one or more parameters comprising a gain.
