Ear Scout: Microphone App APP
It's also possible to record audio and set up an automatic noise-trigger to get notified via email that a specified noise level threshold was exceeded.
Whether you want to responsibly audio-monitor your environment, or just amplify sounds for fun, Ear Scout streams the audio from the mic to your headphones in real time. To fine-tune the incoming signal, use the audio equalizer.
DISCLAIMER. This app is for non-harmful sound amplification (e.g. listening to nature / property monitoring), not to listen in on private conversations via Bluetooth. Use Ear Scout responsibly.
