Abstract
In one embodiment, a method includes outputting, by a slot speaker, an audio signal x(n) and determining, at each of number of different positions i, an audio signal yi(n) resulting at that position from the output audio signal. The method further includes determining a multi-position equalization filter for the slot speaker by optimizing an equalization filter metric that reflects (1) a difference between an unequalized response at each position and a transient-filter equalized response at each respective position and (2) the number of positions at which the transient-filter equalized response has less artifact energy than the unequalized response.
Claims20
A method comprising:
- outputting, by a slot speaker, an audio signal x(n);
- determining, at each of plurality of different positions i, an audio signal yi(n) resulting at that position from the output audio signal;
- determining a multi-position equalization filter for the slot speaker by optimizing an equalization filter metric that reflects (1) a difference between an unequalized response at each position and a transient-filter equalized response at each respective position and (2) the number of positions at which the transient-filter equalized response has less artifact energy than the unequalized response.
A system comprising an electronic device comprising:
- one or more non-transitory computer readable storage media storing instructions;
- and one or more processors coupled to the one or more non-transitory computer readable storage media and operable to execute the instructions to:
- output, by a slot speaker, an audio signal x(n);
- determine, at each of plurality of different positions i, an audio signal yi(n) resulting at that position from the output audio signal;
- determine a multi-position equalization filter for the slot speaker by optimizing an equalization filter metric that reflects (1) a difference between an unequalized response at each position and a transient-filter equalized response at each respective position and (2) the number of positions at the which transient-filter equalized response has less artifact energy than the unequalized response.
The system of claim 18, wherein determining the multi-position mixed-phase equalization filter further comprises executing a multi-position transient response slot equalization algorithm.
One or more non-transitory computer-readable storage media storing instructions that are operable when executed by one or more processors to:
- output, by a slot speaker, an audio signal x(n);
- determine, at each of plurality of different positions i, an audio signal yi(n) resulting at that position from the output audio signal;
- determine a multi-position equalization filter for the slot speaker by optimizing an equalization filter metric that reflects (1) a difference between an unequalized response at each position and a transient-filter equalized response at each respective position and (2) the number of positions at the which transient-filter equalized response has less artifact energy than the unequalized response.
