Abstract:
This paper describes a single DSP implementation of a realtime 3D sound synthesis algorithm dedicatedly for mobile applications. This approach is distinctive in that the audible frequency band is divided into three subbands in such a way that, given a head-related transfer function (HRTF), the portion of the functional behavior in each subband can be realized efficiently by a distinct digital filtering structure. The whole digital filters are implemented on a commercially available 16-bit fixed-point DSP, taking account of three major design factors of memory size, calculation accuracy, and computational complexity. As a result, the realtime 3D sound synthesis is achieved by employing a single DSP with the low computational labor of 51.3 MIPS and the small memory space of 4.6 k words.
