Why not remove the Apple firmware and install rockbox?

Then you can drag and drop to your hearts content :-)

Just looked at the link. Shoulda looked before my last post :-)

Well maybe.
What about power? I need to power any device in a car and in the home.

My FM transmitter is just about OK in my car but would have been nice
to boost it a little to improve Sig/Noise ratio.

More seriously, if you can't find an mp3 player that outputs a high enough
level then you could experiment as follows. (Assuming you are happy to
solder leads, etc.)
Never happier.
Actually that's a slight exaggeration.

Buy a couple of the small signal transformers sold by CPC or similar. Try
using those to step up the output from the player. I have no idea if that
will work, but may be worth a punt if all else fails.

Possibly - thanks for the idea.

I'd assumed the mp3 player would be battery powered as an item meant for
portable use. The transformers obviously don't need powering. So I'm not
clear what you are asking about.

boost it a little to improve Sig/Noise ratio.

The transformers in my CPC catalogue list step up ratios of 1:4 and 1:10.
If the impedances are suitable, etc, that could mean up to a 12dB or 20dB
improvement.

LS01463 and LS01464

I've never tried them for a task like you one want, so can't say if how
well they'd work. But they are quite small and cheap, so if it were me I'd
give them a try.

That makes sense. :-) Although I tend to use ROX on top of Ubuntu/Xubuntu
as I find that makes D&D even more convenient.

Slainte,

Why hate iTunes? You don't have to use it tobuy anything but
it really is quite good at managing the contents of an iPod.

I know some people like it.

I guess I can't see what could be easier than dragging and dropping in
Windows. Simply using my mp3 player in the style of a memory stick.


It's useful for things like podcasts, audio books etc. where it will
keep track of your downloads and, if required, delete from your ipod
podcasts you've listened to.

How about a dual op-amp and 4 resistors?

One of the reasons I suggested transformers is that - unlike op amps - they
don't require powering. But, yes, if power is available then a couple of op
amps, etc, should work.

Hmm, didn't realise that. In my ignorance I thought they would.
