Audio retrieval with frame coefficients of wavelet packet best base and pyramidal algorithm;

用小波包最好基结构系数和塔型算法检索音频数据

Upon production the best base,the method which transform the best base child space into the numerical value denote format of the best base child space has been expatiated.

根据小波包变换的的特点,在产生最好基子空间的基础上,阐述把最好基子空间转换成最好基子空间数值表示形式的方法。
