Abstract: In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feedback delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.

Abstract: In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feed-back delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.

Abstract translation: 在一些实施例中，用于响应多声道音频信号的信道产生双耳信号的虚拟化方法，其通过使用至少一个反馈延迟网络（FDN）向每个信道应用双耳房间脉冲响应（BRIR） 将通用的后期混响应用于频道的混合。 在一些实施例中，输入信号信道在第一处理路径中被处理以向每个信道应用用于信道的单信道BRIR的直接响应和早期反射部分，并且在第二处理路径中处理信道的混合，包括 至少一个FDN应用公共的后期混响。 通常，常见的后期混响模拟了至少一些单通道BRIR的后期混响部分的集体宏属性。 其他方面是被配置为执行该方法的任何实施例的耳机虚拟器。
