Problems solved by technology

[0002] In the prior art, some signal processing devices only include unbalanced signal input ports, not balanced signal input ports, so that the above-mentioned signal processing devices can only support input unbalanced signals, but not balanced input ports with strong anti-interference ability. Therefore, the above-mentioned signal processing equipment does not support audio processing such as mixing, noise reduction, and echo cancellation on balanced signals

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] Since some signal processing devices only include unbalanced signal input ports and do not include balanced signal input ports, they do not support balanced signal processing. In order to enable a signal processing device to support processing a balanced signal, an embodiment of the present invention provides an audio signal processing method and device.

[0055] In one embodiment of the present invention, a kind of audio signal processing method is pro...

Abstract

The embodiment of the invention provides an audio signal processing method and device, and relates to the technical field of audio processing. The method comprises the steps of: obtaining digital signals obtained after analog-to-digital conversion of input analog signals; when there are two paths of to-be-integrated digital signals in the obtained digital signals, integrating the two paths of to-be-integrated digital signals, and integrating the two paths of to-be-integrated digital signals into one path of integrated signals; performing audio processing on the integrated signals to obtain anaudio processing result; and outputting audio signals based on the audio processing result according to the type of currently configured output signals. By applying the scheme provided by the embodiment of the invention, the signal processing equipment can support processing of balances signals.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio signal processing method and device. Background technique [0002] In the prior art, some signal processing devices only include unbalanced signal input ports, not balanced signal input ports, so that the above-mentioned signal processing devices can only support input unbalanced signals, but not balanced input ports with strong anti-interference ability. Therefore, the above-mentioned signal processing device does not support audio processing such as sound mixing, noise reduction, and echo cancellation on balanced signals. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an audio signal processing method and device, so that a signal processing device supports processing a balanced signal. The specific technical scheme is as follows: [0004] In a first aspect, an embodiment of the present inven...
