Audiophiles know that sound reproduction is improved by adding more speakers to a room and making them larger. But that won’t help make today’s increasingly slim and often tinny-sounding laptops, tablets, and phones sound good.
There is a way, however, to make small devices sound larger and better, enabling a high-quality, immersive audio experience, suggests HP Labs researcher Sunil Bharitkar a member of the Media team in HP’s Emerging Compute Lab.
“We can use software to process the audio signals on HP devices so that they approximate the spatial quality of sound that you hear in a room with a multi-loudspeaker audio system,” he says. “We call it immersive audio.”
While competing approaches offer similar processing techniques, the key to HP’s lies in applying specific audio filters and “transforms” that create natural sounding audio with a low compute complexity.
Bharitkar has been guiding an effort at HP Labs, in partnership with colleagues in HP’s Personal Systems and Print groups spearheaded by Personal Systems Chief Technologist Mike Nash, to use this research to upgrade the audio quality on HP’s mobile and desktop devices.
“Audio is an essential, and often underestimated, component of any technology experience, which is why we’re thrilled to be working in close collaboration with HP Labs to make our devices sounds second to none in the industry,” says Nash.
