First let me say I am using MTDaw on a 5th gen iPod Touch using internal mic. I recorded this show holding the ipod by my side in my hand. Once I process everything, I will post a song.
I used this app last night to record a live concert. I set it up to use measurement mode to control the gain because I was recording from the crowd in a small bar with big speakers. The first band goes on, I set up the levels and start recording. The level meter is in the normal range, no peaking at all. Second band goes on, same thing. Main band goes on (for those who care, it was the Spring Heeled Jack/King Django/Vic Rugerio show in New Haven CT).
I start recording. After about 20 minutes, I unlock my ipod to check out the recording. The app crashes out! I'm bummed because some of my favorite songs are now lost

I start up recoding again, catch the last 25 minutes of their set.
Now the next morning, I sync my ipod to my laptop using iTunes transfer. I see the three folders I made, plus a wav file called recovered. I pull the folders and the recovered track. You should have heard me scream when I realized the recovered track was the beginning of the main band that I thought was lost!
Not only is the sound quality amazing but the recovery of the lost track, unbelievable. I wish I knew about this app last month. I tried to record the same band on my Galaxy Nexus and it was bad. Clipped and buzzed audio, a useless recording.
I am giving this app 5 stars on the itunes store and similar review.
I'm sorry for the long rant, it just amazed me how great this worked.
