@SteveTanggithub Hi, You can refer to the following code:

int main(int argc, char const *argv[]){
	SpectrogramObj spec=NULL;

	int status=0;

	int num=0;

	int samplate=32000;

	float lowFre=0;
	float highFre=16000;

	float *mDataArr=NULL;
	float *mDataArr2=NULL;

	int radix2Exp=12; // stft 4096
	WindowType windowType=Window_Hann;
	int slideLength=(1<<radix2Exp)/4;
	int isContinue=0;

	SpectralDataType dataType=SpectralData_Power;
	SpectralFilterBankScaleType filterBankType;
	SpectralFilterBankStyleType filterBankStyle;
	SpectralFilterBankNormalType filterNormalType;
	filterBankType=SpectralFilterBankScale_Mel;
	filterBankStyle=SpectralFilterBankStyle_Slaney;
	filterNormalType=SpectralFilterBankNormal_None;

	num=128;
	status=spectrogramObj_new(&spec,num,
				&samplate,&lowFre,&highFre,NULL,
				&radix2Exp,NULL,NULL,&isContinue,
				&dataType,&filterBankType,&filterBankStyle,&filterNormalType);

	timeLength=spectrogramObj_calTimeLength(spec,dataLength);
	mDataArr=__vnew(timeLength*num, NULL);
	mDataArr2=__vnew(timeLength*num, NULL);
	spectrogramObj_spectrogram(spec,dataArr,dataLength,mDataArr,NULL);
	util_powerToDB(mDataArr, timeLength*num, -80, mDataArr2);
}
