Recording on ipod (was: nano recording volume)

<< < (13/16) > >>

homielowe:
I have a question. I am using an RCA cable to 3.55 female. When "1" and "3" are on "R", and "2" and "4" on L it works, but I'm not sure if this is correct(dual mono?) There are four wires: right, left, ?, and ?. I have no expertise in audio wiring so help would be welcomed.



Soap: Did you have a ground (pin#1)?  Could you explain your wiring technique?

soap:
homielowe,

Assumption 1 being you want a line-in
As for photo one:
(convention says...)
The white wire is Left+, and should be attached to dock pin 6.
The (black / green?  can't tell) insulated wire is probably Right+ and should be attached to dock pin 5.
The bare copper braids/sheaths/wires seen in your first photo are grounds, and should both be attached to dock pin(s) 1 and/or 2.  (For even if both the bare copper lines are attached to the common ground of the 3.5mm jack, the one not attached to ground at the ipod dock end of things will not work as a shield, and could even pick up stray signals.)

As for your second photo, not knowing what you have those two wires connected two inside the dock (or even if they are individual wires seeing as the photo is blurry) I can't comment.


EDIT:  I goofed before and said R+ goes to 6 also, it goes to 5

homielowe:
ok thanks

edit: sorry about craptacular cameraphone pics.

I figured that out myself, wondered why only left earphone make noise

go to that and listen to the file.

i'm not sure if its the right file.

put it on your ipod and listen to it at full volume.  If your really good at hearing you should be able to hear it.

Well the static on that track is at -60 dB, and I can't hear any music.  So you're getting a SNR of at most 10 or 15 dB.   Maybe not even.

I think its pretty safe to say you're just coupling some noise into the power plane, and then registering that on the ADC pins.  If you keep doing this, you'll more then likely destroy your iPod.

gnu:
I read this whole thread and tried to record with my nano through the headphone jack (although I knew it wouldn't work); I did not pump in thousands of volts ;) just a normal line in volume. In the resulting file you can't hear anything at all. I haven't tried it with a dock connector; would that work with a nano?
