Active Linearization Algorithm

USound’s Active Linearization Algorithm (ALA) is an advanced signal processing software designed to enhance audio quality. It aids audio systems developers in further reducing total harmonic distortion (THD) in over-the-counter (OTC) hearing aids and true wireless stereo (TWS) in-ear headphones.

Features

THD reduction

With ALA, MEMS speakers can further reduce the THD, which is especially beneficial for TWS applications, such as Hi-fi headphones and over-the-counter (OTC)
hearing aids.

Real-time processing

In audio applications, real-time processing on a digital signal processor (DSP) enables a system to process audio signals without any perceptible delay, resulting in better sound quality and improved user experience.

A digital graphic featuring the acronym “ALA” in large white letters, standing for Active Linearization Algorithm, with the full name written below in smaller text. Behind the text, a stylized teal and black background displays abstract binary code and a flowing soundwave pattern, symbolizing the fusion of digital processing and audio technology. At the bottom, the USound logo appears, representing the company’s innovative signal optimization technology designed to enhance MEMS speaker performance through real-time distortion correction and superior sound fidelity.

Easy implementation

Using pre-compiled C libraries can simplify the implementation, reduce development time, and result in more efficient and reliable code. The C libraries are compatible with the firmware of the most common Bluetooth® SoC’s on the market.

Optimized for each MEMS speaker

To ensure above-class audio performance, ALA is optimized for each USound MEMS speaker type through thorough analysis and testing.

Integrated into Helike 1.0

Helike 1.0 UA-E3010 is USound’s ready-to-use development board. With Helike 1.0, the effects of ALA on speaker performance can be easily assessed and measured.
