Application of auto calibration and linearization algorithms to improve sound quality of computer devices
Abstract
An application of auto calibration and linearization algorithms designed for correcting acoustic characteristics of selected computer devices was presented in the paper. The functionality of the algorithms were presented for two kind of computer devices: ultrabook class computer and portable device of All-In-One type. The algorithms were adjusted for the given type of the device on the basis of series of measurements conducted on several samples of such type of devices. The key details of the algorithms were presented and illustrated by a practical implementation. The essential improvement of the shape of the amplitude characteristic of loudspeakers built in the devices was confirmed by objective measurements. The presented methodology can also be applied for correction of the acoustic path of other kind of mobile devices.
