The invention discloses an audio frequency adjustment method and device, a storage medium and electronic equipment. The audio frequency adjustment method comprises the steps that the running speed of a vehicle is monitored in response; when it is monitored that the vehicle is in the low-speed driving state, the current vehicle driving speed is determined; determining the multiple of the target playing frequency of the low-speed warning tone corresponding to the current vehicle running speed relative to the reference audio frequency according to the reference running speed corresponding to the reference audio frequency of the preset low-speed warning tone of the current vehicle, the current vehicle running speed and the audio frequency adjustment multiple corresponding to the unit speed difference; and performing resampling according to the multiple of the target playing frequency relative to the reference audio frequency and a preset interpolation algorithm to obtain audio sampling data to be played. Compared with a Fourier transform mode, the audio frequency adjustment method adopted by the invention is lower in calculation overhead.

    本发明公开了一种音频频率调整方法、装置、存储介质及电子设备,包括:响应对车辆的行驶速度进行监测;当监测到车辆处于低速行驶状态时,确定当前车辆行驶速度;根据当前车辆预设的低速提示音的基准音频频率对应的基准行驶速度、当前车辆行驶速度和单位速度差对应的音频频率调整倍数,确定当前车辆行驶速度对应的低速提示音的目标播放频率相对于基准音频频率的倍数;根据目标播放频率相对于基准音频频率的倍数以及预设插值算法进行重采样来获取待播放的音频采样数据。相比于采用傅里叶变换的方式,本发明采用的音频频率调整方法的计算开销更低。
