Abstract

The invention provides a digital audio processing method and system, and the method comprises the steps: obtaining an audio input signal, and carrying out the preprocessing of the audio input signal, and obtaining a first audio signal; wherein the preprocessing comprises the steps of adjusting volume gain, controlling phase transformation and setting related parameters; performing howling processing on the first audio signal through a feedback suppression algorithm to obtain a second audio signal; and performing reverberation processing on the second audio signal through a DSP reverberation algorithm to obtain a third audio signal. Feedback suppression and reverberation adjustment can be processed at the same time, and the applicable occasions are greatly increased; and remote convenient upgrading can be carried out through a network, so that both a user and a developer can efficiently use and develop a product.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a digital audio processing method and system. Background technique [0002] The existing audio processor is a fixed factory software version; the functions included in it include input and output gain adjustment, compressor, limiter, equalizer, delayer, frequency divider, etc. However, the existing audio processor cannot suppress howling; in actual operation, it cannot provide better live effects alone; it cannot be updated through the network, and subsequent new functions cannot be obtained. Contents of the invention [0003] In order to solve the above problems in the prior art, the present invention provides a digital audio processing method and system, which can effectively handle the howling situation through feedback suppression; through reverberation adjustment, it can adjust the audio reverberation information in real time on the spot to enhance the on-site eff...
