Default how do i make a simple delay on one audio channel?

using capacitors and resistors?
Or is there some other technique that i'm just missing out on?
Because I wanted my audio to sound just a little less mono..
because output from my computer is only mono at the moment..
I have over 30 1,000uF capacitors and many resistors if that's what it takes to make even a milisecond delay..
is there some other easier way?
Or am i just wasting my time?
Because I wanted to make a slight delay between the sound getting to my speakers...
how many capacitors of 1,000uF would I truely need to make even the slightest noticable delay?
I'm trying to get a very very slight out of phase to one speaker... but very slight... more of a delay.. so that it would sound at least the smallest bit less monoized.. any have any ideas? (preferably least affecting the voltage to the speaker)
so my speakers would sound a little bit more stereoized. because i only have mono output to my speakers...

Yarrggg it won't let me edit my own post again
I wanted to add I was wondering if there was any easier way to do this?
possibly software wise on my computer?
If not... am I lucked out?

First you should find out why your computer is putting out mono. Solve the 'real' problem. Capacitors and resistors will not create an audio delay.

Darn... that stinks...
My audio output jack was fried a long time ago in a storm..
Now only the left channel puts out clean sound.. and the other... nothing but distorted low volume garbage..

Hi,

A new cheap soundcard is clearly the way to go. Even cheap
with the pace of modern technology is probably far better
than what you currently have, with a lot more features.

FWIW you can't "de-mono" with delay and you can't create
delay with an RC line, you need an LC line, which is all far
too complicated and pointless vs. a cheap new soundcard.

rgds, sreten.

E-pray should turn up older stripped used PC parts dirt cheap.

You can get an external USB audio device.

Hi,

Good grief, this really is silly question and silly information time.

Simply placing two speakers non-equidistant from the listening
position with a mono source will give a fixed time delay, for
the wanted 1mS the distance has to differ by about 34 cm.

It won't make it any more stereo though, as won't equidistant
speakers (so the same level) with one with a fixed time delay.

For the latter the delay will frequency dependently skew the
image towards the advanced speaker, but not by much.

rgds, sreten.

Wow, that's strange. I don't think I've ever seen one without both.
What make and model is it? Old enough to have a floppy disc?
