Embedded implementation of acoustic field enhancement for stereo sound sources

An acoustic field enhancement implementation for stereo sound sources is proposed for dedicated embedded systems. With the use of an embedded DSP-based platform, our distinctive algorithm successfully constructs a signal processing filter structure to enhance the 3D acoustic field through both stereo headphones and stereo speakers. Since this algorithm is implemented by a 16 bit fixed-point DSP with a computational cost of about 50 MIPS and a small amount of memory, high-fidelity spatial acoustics can be achieved in various applications, such as portable stereo players, music streaming to mobile devices, etc.
