Recording lossless audio on an iPod

Hi there,
I have an iPod that I'd like to record lossless audio on (either in *.wav or *. ALAC format. i have an analog output running into a TASCAM IXJ2 Line-In/Mic Converter for Apple iOS. this runs into a lightening to 30-pin adaptor, so it'll fit in my iPod5th gen 64GB. are there any recorder apps that can record in either *.wav or *.alac format at 44100 HZ 16-bit stereo?
It'd be nice if it had auto time/date when you went to save the file and even extra nice if i could auto upload to Microsoft's OneDrive.
does anything like this exist?
I've tried the recorder app that TASCAM puts out for free in the app store, and the handy recorder by zoom but couldn't figure out how to make either of those record anything. if i hit the record butten by double tapping it it just sits there. with either of these apps i can easily monitor what I'm recording as when you open the app the headphone output of the iDevice acts as a record monitor.
anyway do you guys have any ideas?
thanks,
John
