## What is AppSP?

This app is designed to control the parameters of our product, which uses On-Semi Sound Designer firmware chip, a Personal Sound Amplifier (PSA).
This app is intended for use worldwide where the use of the hardware as a PSA is permitted.
Always seek a doctor’s advice in addition to using this app and before making any medical decisions.

This application can only be used on our hardware with firmware version and configuration matching the libraries included in the application.
If you need to add a library, please contact our headquarters to make a request.

Products that meet the above requirements can be controlled by communicating via BLE.
You can input the user's hearing test results via audiogram input or in-situ test and automatically adjust the appropriate amplification based on this data.

You can also adjust the volume, change the memory and display input/output graphs.
You can control noise reduction, feedback cancellation, equalizer, wideband gain, and front-end functions.
