Several Nokia smartphones such as the

1020.[1][2]

The technology has since been replaced by "Dolby Atmos For Headphones", which mainly adds the extra simulation required for the Atmos surround channels to the pre-existing technology. This converts the technology into full Binaural surround. Many argue that Dolby Headphone is superior for virtual 5.1 audio.[by whom?]

History

The headphone virtual surround sound technology was initially developed and marketed by Lake Technology in 1997.[3]

In October 1998, Dolby licensed the headphone surround sound technology from Lake and renamed it 'Dolby Headphone'.

On 23rd Dec 2003, Dolby Laboratories bought over Lake Technology, including the Dolby Headphone technology, for A$21.6 million.

Technology

Head-related transfer functions (HRTFs) are used to generate positional audio cues in the two-channel output signal. A finite impulse response (FIR) filter is used to process the audio with lower latency.
