Abstract
A system, comprising: main circuitry, comprising: a central processor; memory comprising software instructions which when executed by the central processor cause the central processor to: output a first audio signal comprising ultrasonic content; audio processing circuitry configured to: receive the first audio signal; apply first hardware audio effects to the first audio signal to generate first hardware processed audio signal; output an output audio signal derived from the first hardware processed audio signal to an output audio transducer; and a controller configured to dynamically adjust the first hardware audio effects applied to the first audio signal based on a presence or absence of audible content in the first audio signal.

An integrated circuit (IC), comprising:
- audio processing circuitry configured to:
- receive a first audio signal comprising ultrasonic content;
- apply first hardware audio effects to the first audio signal to generate a first hardware processed audio signal;
- and
- output an output audio signal derived from the first hardware processed audio signal to an output audio transducer;
- and
- a controller configured to dynamically adjust the first hardware audio effects applied to the first audio signal based on a presence or absence of audible content in the first audio signal.
(canceled)
A method of dynamically adjusting first hardware audio effects, the method comprising:
- receiving a first audio signal comprising ultrasonic content;
- applying the first hardware audio effects to the first audio signal to generate a first hardware processed audio signal;
- and
- outputting an output audio signal derived from the first hardware processed audio signal to an output audio transducer;
- wherein the first hardware effects are dynamically adjusted in dependence on a presence or absence of audible content in the first audio signal.
