The invention provides a vehicle acoustic early warning method, a computer program product, a storage medium, a controller and a vehicle, according to the vehicle acoustic early warning method provided by the invention, in the running process of the vehicle, in combination with vehicle running data of the vehicle, tone offset processing is performed on original early warning audio data by using a Shannon interpolation algorithm, and the early warning accuracy is improved. The early warning audio data can be used for reflecting the running condition of the vehicle, so that audio playing equipment carried by the vehicle can be used for playing the early warning audio data.

An apparatus and method for generating and outputting display data corresponding to sound sources separated by sound source separation processing and performing correction of each sound source data according to user input are provided. The apparatus includes: a sound source separation processing execution unit that executes sound source separation processing; and a voice data editing processing unit that generates display data corresponding to the sound sources separated by the sound source separation processing and outputs the display data to a display unit. A voice data editing processing unit generates display data enabling recognition of a timing offset, a pitch offset, or the like of different sound source data, outputs the display data together with pitch change data associated with a change over time of the sound source data, and performs processing of correcting the sound source data in accordance with a user input.

The invention relates to the field of audio processing, in particular to a tone synthesis method and device, equipment and a medium, and the method comprises the steps: obtaining a to-be-processed audio and a target tone type; extracting key acoustic parameters of the audio to be processed; determining pitch offset, distortion intensity and band-pass formant according to the key acoustic parameters and the target tone type; performing pitch adjustment on the to-be-processed audio according to the pitch offset to obtain a first signal; performing distortion shaping based on the first signal and the distortion intensity to obtain a second signal; performing resonance enhancement according to the second signal and the band-pass formant to obtain a synthetic audio; and the tone synthesis effect can be improved.
