Inertial effects controller

An inertial audio effects controller is an electronic device that senses changes in acceleration, angular velocity and/or a magnetic field,[1] and relays those changes to an effects controller. Transmitting the sensed data can be done via wired or wireless methods. To be of use the effects controller must be connected to an effect unit so that an effect can be modulated, or connected to a MIDI controller or musical keyboard. The Wah-Wah effect is a classic example of effect modulation.

An inertial audio effects controller can be compared with a traditional expression pedal to explain what it does. An inertial effects controller uses an inertial sensor to detect user directed changes, whereas a traditional expression pedal uses an electrically resistive element to detect changes.There are some advantages and disadvantages between the two.

Availability

Conceivably any or all of the inertial sensors (accelerometer, gyroscope, magnetometer), could be used for effect modulation. However, currently the only commercially available products use acceleration sensing only.[2][3]

Future

Inertial control of an audio device, wired or wireless, is a relatively recent and growing trend as technology advances have reduced pricing and size as well as improved usability and performance of the core components.[4][5] Specifically the core components are an inertial device called a Mirco- Electro-Mechanical-System (MEMs), a microcontroller, and for wireless systems, a radio frequency transmitter/receiver.
