Live Mic is a free audio utility app developed by DevTech Ib. It is a tool that lets users turn their mobile device into a makeshift external microphone, relying on their built-in mics to capture or transmit sound to other apps or devices. It features a simple and intuitive user interface for newcomers.

Instant microphone

Live Mic basically lets you turn your smartphone into a portable external microphone that you can plug into speakers to amplify your voice. You can also use it live for things like presentations, gaming, or streaming, with an additional option to record what you're saying for the latter in case you want to save a copy of that piece of audio.

You can also use the app to turn your phone into a listening device with its Eavesdrop Mode and place it as near to the source of sound as possible. In case you experience an echo loop while near a speaker source, you can enable Echo Mode to try and mitigate this effect. Things to address in future updates would be the audio delay and the inability to work in the background or while the screen is off.

Decent option

To sum up, Live Mic is a handy tool you can use to turn your device into an external microphone for speakers or live. It's easy to use and offers additional options like its listening mode and Echo mode to avoid echo loops. It has its shortcomings, but it is still worth checking out if you're looking for this type of app.
