Ratings and reviews

Hey! This app is almost perfect, but I suspect that the issue is an android issue and not a Cool Mic problem. After connecting to external icecast server from the app and locking the screen, the audio seems to go to sleep a minute or so after the phone locks. Pixel 6, Android 12 with a Behringer UCA 202 connected with a USB-C to USB F adapter. I've gone into app permissions and given it unrestricted battery and unlimited network permissions. Problem persists. 5 stars if you can help resolve! :)

I now have an Icecast server, and after trying a bunch of apps, I'm glad to have stumbled upon Cool Mic! Great design, app is very straight forward and easy to use. One thing that would be awesome would be the ability to stream music to your Icecast server as well as your voice. P.S. I am totally blind, and Cool Mic is fully compatible with Android's built in TalkBack screenreader. Great work guys!

the app works! i want to ask you which are the settings for the least amount of latency. bandwidth irrelevant. i tried a lot but the results differ. thanks!
