The invention relates to the technical field of intelligent driving, in particular to a vehicle-mounted sound equipment simulation sound wave debugging method, system and device and a medium, according to the scheme, part of debugging modules are added in an existing DSP chip, cost is low, occupied resources are few, firstly, normal mute and sound mixing operation is conducted on normally-input simulation sound waves, and then the normal input simulation sound waves are subjected to sound mixing operation; then carrying out multi-division treatment, for example, conventionally dividing two paths into twelve paths; and after sound mixing processing is completed, muting processing is carried out again, opening and closing of each channel are controlled, and then control debugging of the single channel is achieved later. Gaining, reversing, time delay, filtering and the like are carried out in sequence, and finally output is carried out through a loudspeaker; the sound quality of simulated sound waves can be effectively improved through gain, reversing, time delay and filter processing.
本发明涉及智能驾驶技术领域,具体涉及一种车载音响模拟声浪调试方法、系统、装置及介质,该方案通过在现有的DSP芯片中增加部分调试模块,不仅成本低,且资源占用少,首先对正常输入的模拟声浪进行常规的静音以及混音操作,随后进行多分的处理,比如常规的两路分为十二路;完成混音处理后,再次进行静音处理,并控制每个通道的打开和关闭,进而实现之后对单独通道的控制调试。随后依次进行增益和反向、延时、滤波等处理,最终通过扬声器输出;通过增益、反向、延时以及滤波器处理能够有效提升模拟声浪的音质。
