Recording test on iPod nano via line-in on dock connector

That is interesting to know, as I was under the assumption that the Nano had the same internals as an Iriver H10..Wolfson chip in particular:

And thanks to Rockbox the H10 does monitor whilst recording and in record standby mode.

The blipping may have something to do with a switchable ADC high pass filter, which is detailed in the Wolfson Manual, but that is just a guess.

I never noticed any "blipping," and am quite happy with the recording.  I just wanted to pass along my observations.

[Recording Guy]

Fair enough.
 
Actually it was someone else mentioned the "blipping" in this thread.

I got the codec wrong. The sound chip in the Nano 1st is Wolfson WM 8975G.

It works great to me, on my ipod nano 1g!

Wow, really?  So, you have audio at the headphone while you are on the recording screen?  I assume there is no audio when you are actually recording, but only when NOT recording, correct?

I am using a Nano 1g, with 2Gig.  I wonder if there is a hardware difference.

The audio doesn't work when i am recording.
I tested soldering the + power pin (i think it was 22, i dint remember) to the + part of the jack, to record with a normal microphone (without amp) and it worked but very low. I dint know anything about electronic, perhaps there is a better way to get i.
Excuse my terrible English, i think you understand me

I have no audio in both recording mode and while not recording on headphone.
