Many low-end speakers cannot produce good bass (low frequency) effect due to their physical size limitation and cost constraint. Simply equalizing low frequency audio components is usually undesirable because it may cause overload or damage to the speakers. Virtual bass system is a psychoacoustic bass enhancement to produce a virtual bass into human auditory system and trick our brain to perceive the bass, which is physically absent. Currently, the theory and algorithm of this system is well studied. The aim of this project is to allow the author to familiarize with the iOS system development kit, XODE and to implement the algorithm in a iOS application.
