| Abstract: | The idea of soften audio analyzer is presented based on the signal analysis, virtual instrument technology and practicality of sound card. Audio signal analyzer is realized by using the special language Lab Windows/CVI and designing the parts of software and hardware. This instrument has many merits such as soft-upgrade, system self-adapting, windows visual showing and on-line debug optimization etc. This system is applicable to analyze and deal with signal in audio detect system. |
