Abstract
A method for converting a vehicle audio into a surround sound and a sound system are provided. The method includes: extracting features of an audio data for debugging based on a vehicle audio signal; performing classification according to the extracted features to separate the audio data into a plurality of single audio signals; mixing the plurality of separated single audio signals, and recording parameters of the current sound mixing algorithm as original sound mixing parameters; pre-configuring a plurality of spatial reverberation modes; debugging the original sound mixing parameters; and determining and saving optimized audio channel equalization parameters and optimized sound mixing parameters corresponding to the spatial reverberation modes as the multi-channel surround sound conversion parameters.
