In the early days of stereo it was common to get stereo records
realeased with a "mono recording reprocessed to give a stereo effect".

Now that the introduction of DAB has caused many stations to revert to
broadcasting in mono there must be a new market for a "mono to stereo
effect" processor.

Is there such a thing? Do any DAB receivers include one?

Not as far as I know - just buy 2 DAB radios.

At the prices they are now that would be cheaper than any gismo producing
the 'dual mono' which is all you could get from a mono signal!

Or am I missing something....???

From what I've heard of DAB stereo it seemed that it was some sort of
re-constituted mono that was passing for stereo....

In the late '60s, the reprocessed stereo releases had two halves that were
differently equalised and panned and delayed versions of the same mono
input, long before spatial sound gimmickry was heard of. Some eager
re-mastering techs would pan solos and instrumentalists and alter set-ups
for middle eights, separate reverb or/and echo was provided for the
different components, and the sound image seemed wider to an extent, while
remaining mono (sum)-compatible, where a lot of tonal add-ons cancelled or
shrank
Often old singles of an artist/group/band were compiled into LP albums, some
recent tracks were real stereo whilst some older ones were contrived to
simulate width.
This meant more marketting and more sales and further royalties (where due)
could be achieved from tweaking stale historical recordings... which stood
in their own right, anyway.

Use two different speakers for left and right, preferably with
different order crossovers.

Or, what I used in the 1970s is a simple phase-shift circuit feeding
one channel. Constant gain at all frequencies and phase shift varying
from 0 at low frequencies to 180 degrees at high frequencies.
It uses 3 resistors, a capacitor and a 741 (for the classic sound!)

As the general quality of the broadcasts is going down all the time, just
don't bother.
What's not in it, you can't get out.

I am not sure, but I think you may be referring to multiplex decoders that
recover the stereo information broadcast on most commercial FM
transmissions in the UK. If so, this isn't the same thing as 'fake' stereo
from a purely monophonic source.

Slainte,

Jim

That's a multiplex decoder designed to update a mono FM tuner to receive
stereo broadcasts. Although I doubt there are many mono tuners around
these days.

It will have no effect on a mono broadcast.

See, there you go again - that opening line says immediately to me - 'don't
bother with this one, it's conjecture at best, go and get the windows done
while you have the chance'...

Perhaps it's me? - Or the fact that, despite it being a Sunday, I still have
more pressing things to do in this good weather...??
