Default automatic compression of music


I wonder if anyone can suggest whre I could buy a 'box' that would
compress music to a reduced dynamic range.

I listen to the radio in my office at work. there is quite high
backgound noise (about 45dB) from computes in my office but I don't
want to disturb by neighbours though the partition walls.

I listen mainly to Radio 3 on DAB so my source is not compressed. At
the moment I am foreever turning the volume up and down.

thank you,

Robert

Does your radio not have optional compression settings? It is supposed to
be a standard feature of DAB.

DAB offers a compression facility at the receiver - but perhaps not
implemented on your system?

Is it a portable radio or some form of separates? If you can get at the
output of the tuner - or there's some form of tape recording loop, etc -
you could add a low cost compressor from the likes of Behringer.

Personally, I'd find the sound unaceptable, though. The 'Optimod' that
they use on R3 FM at certain times to do just this job costs thousands -
and I'm not keen on those either. ;-)

I take it you can't get decent FM reception in your office?

Thank you Dave,

There is indeed a compress/expand switch on the back of the tuner
(Cambridge Audio Azur 640T. At least, I think that's what it is; the
manual is very vague about what it actually does describing it as
"warm/lively". It does not have a very powerful effect, certainly not
enough for what I need.

I can't get decent FM reception here becuase I can't put up an outside
aerial. If I could I would be using FM rather than DAB.

Thank you Tom Sayer for the offer of an expensive compressor. but I
was hoping for something that was cheaper than the rest of the
equipment I am using.

I listen on a pair of 1970s KEY Concertos, BTW, driven by an Azur 640A.

If you want to keep a reasonable level of quality then I'd suggest looking
at the FMR Audio RNC - they're just under 200 pounds. Alternatively, you
can probably pick up something from Behringer for around 50 pounds.

Cheers.

James.

No doubt at all there is, but processing is abhorred by many but your
need is the reason its done)

I don't think this has anything to do with compression. As you say, the
effect is very subtle, but it seems to be a filter of some kind, a bit
like the "mellow" and "bright" tone switches they used to fit to those
old mahogany radiograms full of thermionic valves. I've left mine in the
"off" setting, and it sounds fine on FM.

That's what a compressor does. They are fairly simple devices, and are mass
produced. so you can get good quality products at low cost. I think the
problem with them is setting them up to get the desired results - most of us
have little experience with compressors.

Have a look at the Behringer site for the Autocom Pro-XL MDX1600

http://www.behringer.com/MDX1600/index.cfm?lang=ENG

and download the manual.

I think you can fit one in the tape-in/tape-out loop of your amplifier, so
you could use the compressor on all your sources ... that would be OK if the
sources had similar signal levels.

You can buy compressors at PA equipment shops (eg Digital Village) or your
local DJ equipment shop. Often they come with extensions for rack mounting,
but they can be removed.

By the way, if you have audio processing software on your computer, you can
probably set up a software compressor. That would at least let you judge
the audio effect without spending any money.
