People on Amazon ask some of the stupidest questions (he said, as he's
about to ask one).

I"m looking at a panel-mount extension cord for a car radio with USB and
3.5mm inputs, and someone asks "could i use this to connect a usb
headset to the 3.5mm headphone jack on my tv?"

And all the answers related to the fact that it uses two unconnected
cables, and about converting from one jack to another, and I thought the
problem was deeper than that, that there is no way to make an adapter
from the audio output of a 3.5mm jack to a USB headset, because, well,
it's USB! It's uses some sort of fancy USB signal, like all the other
USB devices do. It doesn't have L+, R+ and ground, like earphones with
round plugs on the end have. OR does it?

BTW, I use little powered Logitech USB speakers with my laptop and they
get their power from the USB, and they work very well. If I'm wrong
above, does the power piggyback on one of the 3 wires or does it use the
fourth wire?

Tnx.

Maybe the 5th - the shield ground?

**No.

**No, it doesn't. USB (Universal Serial Bus) is a digital connection
system. Any audio signal present is in a digital form and must be
converted to analogue, before it can be heard.

transferred to devices that require it.

It took a while for this to sink in but I think you're right. Maybe the
adapter has some converter. It's coming from China and it's made it to
California and will arrive in a week, and I'll know then. ;-)

Otherwise, I think I can convert the mp3's to .cda's though I haven't
found a converter yet that will do a whole directory, not just one at a
time.

..cda's are iirc 4 times as big as .mp3's but flash drives are so big now
the only problem is the time it takes to convert things.

Goldwave (http://goldwave.com/release.php#download) has a "Batch"
conversion function. Not sure if it is available for free; I have had a
licence for years.

I have a new plan, which is to spend more money. I made it from 65
almost to 71 without running out of money, and if I up my spending , I
think I'll still be okay. (Of course for me, that's only 200 or 300 a
year.)

It took me a while to find the price: US$45 (Lifetime) • US$15 (One
Year)

Wow, It does a lot of things. I'll probably never do anything but
conversions to CDA, and only until I get a car radio that plays MP3s,
but that will probably be 6 or 7 years.

There is so much interesting stuff to do. I wish I could live another
100 years.

BTW, "batch" is the word I should have been looking for. It's not like I
don't know the word from IBM mainframes going back to 1977.

Is it ungrateful to y ou to post that if you search on

batch conversion mp3 to cda

even without the word 'free' there are 3 or more free ones. So if one
works well, I have the $45 for mad-money.
