Active Linearization Algorithm

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.

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.
