Abstract：Theconversion ofaudio signals into light usually involves converting the frequencyinformation of the audio signalsintotheintesityolor，orbrighesschangesofthlghtsignals，esultingintepenomenoofisucientcolorand intensityofthe light signalsand displaydelay.Acontrol methodforaudioacousticsignal adaptive mappingof opticalsignal technologyisproposedinispperIepreprocesingstage，itextractsthespectralcharacteristicsofthespectralergyand spectralcenter，focusingonanalyzingvarious characteristicsof pitch，timbre，hythmanddynamicchanges inaudiosignals.
