Abstract:
The present disclosure provides a multi-channel morphing digital audio filter, including methods and systems for real-time interpolation between a plurality of fixed frequency responses. Real-time interpolation may be performed simultaneously along three separate axes. Various embodiments of the present technology include receiving, in real-time via a digital filter module, at least one acoustic signal and one or more control input signals indicative of one or more corresponding interpolator values. The methods and systems may further include determining one or more filter coefficients based on a linear interpolation in an encoded space of a plurality of fixed frequency responses, generating a filter from the one or more determined filter coefficients, and applying the generated filter to the at least one received acoustic signal. In some embodiments, frequency and amplitude (i.e. angle and radius) of poles and zeros of the filters may be processed independently, and poles may be unconditionally stable.

Claim (Index 20):
A method, comprising:\n receiving, via a digital filter module, at least one acoustic signal; receiving, in real-time, first, second, and third control input signals indicative of first, second, and third interpolator values; determining one or more filter coefficients, the determining comprising, for each corresponding filter section of the plurality of fixed frequency responses:\n interpolating, based on the first, second, and third interpolator values and encoded values from a plurality of encoded filter parameter tables, encoded values indicative of a pole and a zero of each of the plurality of fixed frequency responses; \n decoding the interpolated encoded values; and \n calculating a section output based on the decoded values, \n the determining one or more filter coefficients further including interpolating, based on the first, second, and third interpolator values and the encoded values from a plurality of encoded filter parameter tables, and decoding an encoded value of a filter gain; \n generating, in real-time, a filter from the one or more determined filter coefficients, the filter being unconditionally stable; applying the generated filter to the at least one received acoustic signal; and transmitting the at least one filtered acoustic signal.
