Design of arbitrary delay filterbank having arbitrary order for audio applications

Literature shows that the design criteria of p^th order analysis having q^th order synthesis filters (p ≠ q) with a flexibility to control the system delay has never been addressed concomitantly. In this paper, we propose a systematic design for a filterbank that can have arbitrary delay with a (p, q) order. Such filterbanks play an important role especially in applications where low delay-high quality signals are required, like a digital hearing aid.
