Haptic Audio

What Is Haptic Audio?

Haptic audio is the practice of designing sound and vibration together as a single sensation, so that what users hear and what they feel through a device reinforce each other. When the audio waveform and the haptic pulse are precisely matched in timing and character, a purely digital event acquires convincing physical weight.

Haptic Audio in Practice

Apple is the reference point. Its Taptic Engine, introduced with the Apple Watch in 2015 and later built into the iPhone, is a linear actuator capable of vibrations precise enough to be composed like sound, and Apple’s Core Haptics framework lets designers author audio and haptic patterns as one synchronised score. The result is felt everywhere in iOS: the reassuring pulse of a successful Apple Pay transaction, the ticks of the scrolling picker wheel, the click of the Digital Crown. Games consoles have followed, with controllers that render explosions and rain as matched sound and vibration. For brands, haptic audio extends sonic identity into the sense of touch, making a signature interaction recognisable even with the volume off.
