SVS is a revolutionary audio process that emulates, in headphones, the complete experience of listening to actual loudspeakers in an actual room, in up to eight-channel surround sound.

The emulation includes the precise localisation of all the speakers in the room, the room acoustics, and the response of the speakers and all electronics in the emulated system.

The emulation is essentially perfect, meaning that in immediate A/B comparison between the actual speakers and the headphones, listeners say the two are indistinguishable.

This breakthrough has far-reaching benefits which audio professionals, home listeners, and game players are only beginning to assess. The relationship between the listener, the listening room, and the sound system is changed completely.

Smyth Research

Smyth Research, with laboratories in Bangor, Northern Ireland UK, was founded in 2004.  The company engages in research and development related to hearing and sound reproduction in three dimensions.  Our present work is focused on virtual sound reconstruction of real sound fields.  The potential of headphones in this application has never been fully realised, until now.


"...my impression of sound field reality was so convincing that initially I was sure that the headphone simulation was in fact inoperative and that I was still listening to the real speaker system...."
