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!

Jas. O. Feb 2, 2019     

Good design, easy to use, but the latency is around 15 seconds! If I use Butt on Windows I get 2-3 seconds latency.

I would give 5 stars but for some reason it won't let me load audio files.

Bakwaas tarin app waste of time

Finally app I need, definitely not perfect but great. Looking forward to perfect situation to use it. I'd like to see mute button at all costs because I don't have to plug fake microphone into my phone. Also maybe the VU meters can be put to better position so I would look like better ald I can see stereo separation even more. GJ THAT IT DOESN'T CONTAIN ADS

The app works great, no problem with streaming to Icecast. I'd love to see Opus version 1.2 in the next update :) There's a minor annoyance though, on the main screen I have a light grey background, and it's hard to read the white text on it. I use Android 7.0 on LG G5

Nag. C. Aug 31, 2018     

Need option for broadcast androd system sound also... With out it how can i mix or play sound or songs? If i use external sound mix... why i can use ur app in my mobile? I need get sound source from my mobile sound. Ex if i play fm radio in my mobile i need broadcast what playing in my mobile.. Need broadcast my android sound source not only mic

Pet. W. Aug 23, 2017     

I like this app. What would be great was the option to record the outgoing stream to a local file on the phone (.ogg or .opus) and maybe some control over the audio level?

Bia. E. Feb 16, 2017     

The sound is amazing! Great app and easy to use
