I have an app that does some processing of the recorded audio signal. After some testing over different devices, 1st gen ipad and iphone 4 appears to have sagnificantly lower input levels when recorded by a same device attached to a mic port.


Tested and confirm good recorded levels on following devices:

1) 2nd gen ipod

2) iphone 4s

3) ipad 3


Low levels:

1) iphone 4

2) 1st gen ipads



Any ideas what can cause this? Can i somehow amplify recorded sound?

iPad, iOS 5.1
