摘要
结合均匀滤波器组的加权叠接相加法和短时全通变换,设计了一种可以模拟听觉感知模型的非均匀滤波器组。该滤波器组可用于实时信号处理。仿真结果显示,设计的非均匀滤波器组可以模拟Bark频率尺度,且具有比较理想的信号重建功能。
A non-uniform filterbank based on weighted overlap-add method and short-time allpass transformation is proposed, which incorporates a perceptual model of the human auditory system and can be implemented in real-time.Simulation shows the non-uniform filterbank has approximate Bark-scaled frequency resolution and can reconstruct signals well.
