## Description

**Cool Mic** is a versatile open source livestreaming tool designed for Android devices, enabling users to broadcast live audio directly to any Icecast server. Utilizing modern open-source audio codecs such as Ogg/Opus and Ogg/Vorbis, Cool Mic provides high-quality audio streaming that's both reliable and efficient.

Featuring an intuitive and simple user interface, Cool Mic empowers users to insert audio segments during broadcasts, adjust input gain, and monitor broadcast metrics like active listeners and stream length. The app supports rich metadata updates mid-stream and offers configuration flexibility including server ports, audio quality, and source usernames. Additional features include auto-reconnect, QR code auto-configuration, and integration with Cool Mic Test Servers for connection testing. Entirely open source under GPLv3, it uses libshout for seamless Icecast communication, making it an excellent choice for open audio streaming projects.

## Review summary

Cool Mic is praised for its ease of use, good design, and reliable streaming to Icecast servers, including compatibility with accessibility tools. However, multiple users report limitations such as lack of MP3 streaming affecting device compatibility, audio playback issues, high latency, and streaming interruptions when phones lock. While some connectivity problems exist, overall it is considered a solid app for microphone-based streaming with room for improvement in latency and format support.
