Remarkable haptic experiences driven by cutting-edge hardware and intelligent firmware.
Lofelt Wave Firmware
Maximize performance and efficiency with intelligent haptic signal processing.
Generate high-resolution haptic signals from existing audio input and manage actuator behavior in real time – no need for tedious pre-programming and additional APIs, signal generation or outputs.
Accommodate a variety of standard analog or digital audio input (e.g. I2S, SPI). The DSP libraries are customizable and easily ported into different hardware architectures.
Transform audio into high-definition haptic feedback in less than 5ms system latency, guaranteed to keep the haptics in sync with what you hear and see.
Lofelt Wave modular processing chain delivers the best possible user experience.

Based on a voice coil design, L-series actuators display significant advantages over traditional ERM, LRA, EAP and piezo technologies.
This patented actuator is design-in ready and available to ship at mass production quantities. It features true wideband response, high acceleration, low voltage and is RoHS/REACH compliant. The L5 is designed for medium-sized devices like headphones, laptops, gaming and VR controllers, computer mice as well as other input peripherals.
See it in action in the Razer™ flagship wireless gaming headset.
This cylindrical voice coil actuator uses optimised magnetic flows to deliver maximum force while maintaining optimal precision over low frequency ranges – ideal for full-impact immersive gaming with realistic texture renderings as well as high-fidelity clicks and touchscreen effects for automotive applications.
Lofelt uses state-of-the-art software simulation to guarantee optimized actuator designs. A full understanding of the physical model and fatigue behavior delivers optimal performance with the highest production quality standards.
Rapid prototyping with Lofelt Wave firmware and hardware – for a variety of audio-to-haptics applications.
The evaluation kit (EVK) converts any standard stereo audio input – games, movies, VR or music – into a high-resolution haptic signal in real time. The haptic actuator included in the kit translates the signal into high-definition vibrations for natural tactile feedback.
Each PCB section can be broken out to fit inside target prototype hardware like headsets, gaming/VR controllers and other input peripherals. The DSP can also be easily adapted to different application thanks to the modular design of the signal processing chain.
