Title:
AUDIO APPARATUS AND SELF-OSCILLATION DETERMINATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/255317
Kind Code:
A1
Abstract:
This audio apparatus (1) comprises: a filter processing means (4) for performing a filter process for processing the waveform of an input signal and performs an output; an adjustment operation means (5) for prompting the operator to adjust control parameters of the filter process by the filter processing means (4); an input signal acquisition means (6) for acquiring the input signal to the filter processing means (4); an output signal acquisition means (7) for acquiring the output signal filtered by menas of the filter processing means; a self-oscillation determination means (8) for comparing the frequency components of the acquired input signal with the frequency components of the acquired output signal, and determining whether or not self-oscillation has occurred, on the basis of the synchronization state of the input signal and the output signal; and a self-oscillation notification means (9) for externally notifying that the self-oscillation determination means (8) determines that self-oscillation has occurred.
