Efficient Multichannel RLS loudspeaker signals are mutually correlated. This chapter presents a multichannel adaptive filter which uses a joint update rule for all filters. Experiments are carried out to confirm the operation of the multichannel adaptive filter and compare it with the performance of separately updated adaptive filters.

As sound sources are wideband, temporalspatial filtering is required which is generally more complex than spatial filtering alone. Array signal processing includes estimatin

The convergence can be extremely slow however when working with real-life audio signals and long filters. Moreover, the computational complexity grows line
