The app is available under the name 'MicDroid' in the market, and the source is available at my github, http://github.com/intervigilium/MicDroid
There's still a lot of work to be done, including pretty much the entire GUI.
Currently my priorities are like the following:
1. device compatibility, I have reports of failure on G1, MyTouch3G, Galaxy S
2. graphics (being worked on)
The reason I'm posting here is because I don't have most devices (anymore), and would like some testers with different phones to get me some logs. Testers and feedback would be greatly appreciated!
If you run into force-close, or general app failure, grab LogCollector from the market, run it after my app fails, and send me the log!
