Abstract
There is disclosed in one example an audio processor, including: an audio crossover to separate a first frequency band from a second frequency band, the first frequency band having a lower frequency band than the second frequency band; an excursion estimator to estimate from information of the first frequency band a predicted excursion of a low-frequency driver; an interpolator to interpolate an adjustment to the second frequency band to compensate for the estimated excursion; and circuitry to drive the adjusted second frequency to a receiver.
