AI Technical Summary

Problems solved by technology

It is extremely difficult to write, and ordinary users cannot customize sound effects according to their own needs.
A good sound effect usually has multiple functions such as reverb, mixing, ducking, etc., which increases the difficulty of editing DSP sound effects

Abstract

The invention provides a method for configuring an external sound card. The method includes the steps that modularization processing is conducted on sound effect algorithms which are written with a special programming language so as to form plug-in modules which are represented with graphs and comprise input interfaces and output interfaces; the plug-in modules are combined through the input interfaces, the output interfaces and connecting lines according to design requirements so as to obtain a sound effect module; an algorithm instruction set corresponding to the sound effect module obtained after combination is compiled so as to obtain a binary code through which a special audio device arranged on the sound card can execute instructions; the binary code is downloaded into a memory of the sound cart in a communication mode. According to the method for configuring the external sound card, edition of the DSP sound effect can be simplified, and thus an ordinary user can edit and use the DSP sound effect.

Description

technical field [0001] The invention relates to the technical field of audio digital signal processing, in particular to a method and device for configuring an external USB sound card. Background technique [0002] Compared with the onboard sound card and PCI sound card, the USB external sound card is far away from the complex electromagnetic interference environment of the chassis, and the sound quality is better. And because of the portability of the USB external sound card, the application of the USB external sound card is more and more extensive. [0003] Because the audio DSP dedicated chip has the characteristics of fast speed, high efficiency, and low delay in processing sound effects, the current USB external sound cards with better performance use audio DSP dedicated chips to process sound effects. [0004] However, the DSP sound effects of most USB external sound cards are written by professionals with relevant DSP instructions. Dane's grammatical format is simil...
