Abstract

The realization scheme of ldquoout of headrdquo sound field enhancement for headphone is proposed, which is dedicated to embedded systems. The stereo enhancement system renders out of head localization by simulating virtual loudspeakers in the room, using head-related transfer function (HRTF) filtering and adding slight reverberation. Further more, the memory and computation consumptions are reduced with CAPZ models and simplified reverberation algorithm. The system is implemented on the Blackfin533 DSP platform. Experiment results demonstrate that the system can achieve excellent spatial enhancement effect for stereo audio with low computational cost and a small amount of memory.
