Recording on ipod (was: nano recording volume)

[axlgreasetires]

I didnt really read any previous posts.  but the reason i replied is to say recording does work through the headphone jack.  i tried it and i can hear distinguishable sound.

i can't wait for the gain thing to work.

What model iPod?
What source form the recording menu (line-in or mic)?
What did you input into the headphone jack?  A microphone?  A line-level output?  A speaker-level output?  Other?

I too had some excellent results recording through the headfone jack, details are:

Ipod Photo, 60gb

Dynamic Microphone - XLR to 1/4" input with a (stereo) 1/4" to 1/8" plug.

I recorded some drums at 16bit 44khz with just the one mic, it sounded fantastic, I was really excited about it.  But all of a sudden my XLR to 1/4" cable stopped working and when I tried with my mate's I started getting conciderably less volume - It hasnt been the same since...  

I have a Griffin iTalk - the unit that plugs into the top of the Ipod - it has a Mic Input on it but I cant get this to work - I bought a little Sony stereo microphone and would love to use the iTalk, iPod and stereo microphone to record samples at 16bit 44khz... any idea if there is Griffin iTalk functionality planned?

Peace.
Dan.

yeah basically what he said except i have a 30gb video and i was recording myself playing guitar.  I recorded with a wire that looks like:
-=---------------=-

so it has two little sterio mini end things.  i'm not sure whether i used line-in or mic.

the song i was playing is uber hard to hear but it is distinguishable.

Did you go straight from the 1/4" jack on your guitar to the headphone jack of the ipod, or did you go through an amp?

I think in dan gii's case the recording through the headphone jack is plausible.  On the iPodLinux site they list the photo as only being able to record via "microphone".  So at least in principle that target has the hardware to allow it.  

It is not clear to me that the nano or video have this capability.

my guitar was connected to the amp.  the amp was outputting to my ipod.

Unless Apple has been lying to us, you have no microphone input through your 5th generation's headphone jack.
That leaves a very scary probable explanation for the results you were getting.
Through the act of pumping an amplified signal into your headphone jack, you pumped enough power into your output lines to jump over and induce voltages on other wires, wires not physically connected to the headphone jack.

Think about that for a second.

as I said over two weeks ago...

okay i tried this on my 5g. i plugged my computers audio into the headphone port (volume all the way up), recorded through line in and mic, then played it back on my computer (volume all the way up) and didn't hear jack crap.

You don't have a mic-in port.
Unless you bought (or made) a dock connector you don't have a line-in port.
It is no wonder you didn't hear anything.

People!  There is Nothing Good which can come from pumping amplified signals into the headphone jack of your iPod w/o a mic-in.

Yo thats because your a noob.

It works i tell you>.. It works!

I recorded again.  WITH EVEN BETTER RESULTS.
i recorded on line in
Format : MP3
It still sounds crappy but i can hear sound that is easyly distinguishable from background hum and hiss.

I could upload a recording for you.

Hey, I don't care if you fry your iPod.  It's your decision.  But I will wait to get a proper line-in dock connector so that I don't have to supply amplified signals to my iPod and hope for pickup due to crosstalk.  I mean I can generate crosstalk in separate channels of a ADC in my lab, it doesn't mean that this is a preferred  method of recording signals or keeping usable equipment.

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.

axlgreasetires, compare your attempt at burning iPod traces with my proper line-in recording:

When gain is implemented, it won't fix your underlying issue.


(short enough I believe it constitutes fair use)

Success 


I might have screwed up th soldering because midis outputed from my phone comes up as http://www.sharebigfile.com/file/72145/R070129-191423-mp3.html (might be dual  mono)
but the midi is below
the midi from my phone is

I wish playback wouldn't die though

any help would be welcomed
edit: further testing reveals there is little if none audio coming from the left channel(mighy have soldered the ground)

Before you go and disassemble your whole adapter, double check that you are actually getting full insertion into the iPod's dock connector.  I wasted a lot of time once trying to find fault in a line-in / line-out pair after testing revealed a weak channel, only to find that the problem was simply a failure to seat the plug firmly in the dock.  
Hopefully your fix will be as brain-dead simple.  If not, don't give up!

Congratulations.  You've recorded noise.  I don't hear ANY guitar in there at all.

By the way, what output on your amp are you using to do this?  PLEASE tell me that it's not a speaker output.
