Additive background noise and convolutive noise in the form of reverberation are two major types of noise in audio conferencing and hands-free telecommunication environments. To reduce this type of acoustic noise, we propose a two-step approach based on subband adaptive filtering techniques. In particular, we first reduce the additive noise using a Delayless Subband Adaptive Noise Cancellation (DSANC) technique, and then suppress the convolutive noise through Subband Adaptive Blind Deconvolution. The experiments show that our method has lower computational complexity and better performance than previously proposed methods.
