Smart AMP

[NOTICE] Please connect your earphones or pair your Bluetooth headset before starting the app. Set the volume to a comfortable level before you start, and avoid listening at a high volume for long periods. Smart AMP is a personal sound amplifier (PSA) app. It picks up the sounds around you through your phone's microphone, amplifies them in real time, and plays them back through your connected earphones or Bluetooth headset. Use it when you want to hear quiet sounds a little more clearly - a conversation in a noisy cafe, a lecture in a classroom, or the TV across the room. Main features - 64-channel nonlinear precise compression - Noise reduction (NR) based on probabilistic analysis - Feedback cancellation (FBC) - Microphone and earphone sensitivity calibration - Independent left/right control, four presets, and a custom setting All processing runs in real time on your device. The app does not record, store, or transmit any audio. The output level may vary depending on your phone model, volume settings, and the type of earphones or headset you use. Requires iOS 15.0 or later. [IMPORTANT] This app is a personal sound amplifier for everyday listening. It is not a medical device. It does not test, diagnose, or treat any condition, and it is not a substitute for a hearing aid. If you have persistent difficulty hearing or any concern about your hearing, do not rely on this app - please consult a doctor or a hearing care professional. Always seek a doctor's advice before making any medical decision, whether or not you use this app.
