摘要

提出了一种利用最优准双正交(OQB)滤波器在一个倍频次滤波器组结构中模拟房间脉冲响应的方法。进一步表明，多相自适应滤波器结构(PPS)或对数变换可以获得精确的子带参考响应，并且子带中的等阶滤波器可以获得令人满意的结果。

The application of optimum quasi bi-orthogonal wavelets to the simulation of room acoustics

A method to simulate a room impulse response using optimum quasi bi-orthogonal (OQB) filters in an octave filter bank structure is demonstrated. It is further shown that the poly-phase adaptive filter structure (PPS) or the log transform can be used to obtain accurate subband reference responses and that equi order filters in the subbands yield satisfactory results.
