有参数，小程序的TS类型有问题  private async _decodeAudioData(buffer: ArrayBuffer) {     // const buffers: AudioBuffer[] = []     return new Promise<AudioBuffer>((resolve, reject) => {       // @ts-ignore       this._context.decodeAudioData(buffer, (buffer: AudioBuffer) => {         resolve(buffer)       }, (err: any) => {         console.log(err);         reject(err)       })     })   }
