Audio signal processing techniques are described which are employed within a circuit of a speech dereverberation system. The amount of data or number of samples input to a reverberation coefficient determination unit is determined, taking into account information about the background noise in the acoustic space and information about energy of reverberant sound in the acoustic space.
