纳老师您好,
我用了实录的音频(有一定的震动)跑您这份代码,貌似效果不太稳定,可能比nlms要差。我试过用频域的auxIVA去做回声消除,中高频效果不错,但是低频部分比较差。您那边有更接近工程实际的解决方法吗?
此外我用auxIVA做通话降噪用,如何区分人声和干扰呢?后面我用了overIVA去做,但是混响环境下的效果远不如消声室的录音,不知道您那边有没有办法使它在混响环境下提升效果?

请问下aux-iva的实时性怎么样?我之前担心计算量太大,一直在自然梯度上做。方便的话可交流。

我的实测场景效果也非常的差,我使用subband 方法,用的是Cosine 调制的滤波器组。
是不是如果有非线性失真,会放大失真,造成更坏的结果。
