Ben Supper - How's your spatialisation algorithm?

Presented by: Ben Supper, Independent Everybody seems to have an algorithm that purports to steer a sound around an environment that exists only in a pair of headphones. By the time you get home, your family pets will be pitching their new API that gives a content creator 360-degree control over source position, distance, source width and room size, and also works on gerbils. Spatialisation is suddenly important to large corporations because VR and AR are making the transition from tech to media, and media makes money. However, it has always been important to acousticians. Playing tricks on the mind, well or badly, yields the richest information about what happens when a sound wave hits the squishy part of the signal chain. How does the brain actually make sense of whatever is happening at the ears, and place it in a spatial context? Do individual HRTFs matter? Is head tracking important? How good, and how bad, does a simulated room need to be? How is some research misleading, and where does your computing power need to go? What creative tools might be needed? And what's so bad about getting it wrong, anyway? This is a spatial psychoacoustic primer about how these algorithms work that's a bit polemical but mostly informative.
