Wireless and miniaturized audio devices require lightweight drivers with a slim form factor, which can also deliver outstanding audio performance. To achieve that, audio systems developers are required to monitor the THD - the measurement of the harmonic distortion present in a signal - of MEMS speakers. The new signal processing tool provides an additional measure for reducing the THD, setting new standards for the entire industry.
"ALA enables audio systems developers to significantly reduce the THD of MEMS speakers, which, in turn, improves the audio quality of end products. USound continuously researches and develops audio solutions that set new standards on the market. The release of ALA software tool is another turning point for USound and the entire audio electronics industry," says Ferruccio Bottoni, USound’s CEO.
ALA can also be applied to a system that has been already optimized to improve the THD performance. By digitally compensating the non-linearities of the speaker driver, ALA helps developers to further reduce the THD and improve the audio quality of an end device. This will not only benefit MEMS speaker-based audio system manufacturers, but also improve the experience of end users, including patients with partial hearing loss who will be able to enjoy slimmer hearing aids with improved audio quality.
The ALA software tool is already available for purchase.
