【摘要】 根据厅堂冲激响应能量主要集中在低频段的特点,提出了将高频段和低频段分别处理的混响算法。仿真结果表明此混响算法能逼真地模拟厅堂的自然混响特性。最后给出了基于此混响算法的数字混响器的硬件设计和音频信号处理流程。实验证明在该系统平台上可以很好地运行多种混响效果算法。更多还原

【Abstract】 Based on the fact that the energy of the hall impulse response mainly focuses in the low frequency, the reverberating algorithm processing the high-frequency band and low-frequency band separately is presented. The hardware design and audio signal processing flow chart and scheme of realizing digital artifical reverberation are analyzed. Experimenal results show that the reverberating algorithms run well on the platform of this system and several natural reverberation effects of halls and rooms can be simulated.更多还原
