OK, I've got a mystery I need cleared up before I can do anything else:

If I record in Stereo (with the amp's balance swung over to one speaker, in
front of the single mic) I get this:

If I set the recording software (Sound Forge) to Mono, with *nothing else*
changed I get this:

http://www.apah69.dsl.pipex.com/show/Mono%20Tenor.jpg


Note the 'upper limit' differences - what is going on here that I should
know?

(Excuse slightly different start points/lengths on what should be identical
clips!!)


Baffled? I know I am....!! ;-)


Something strange in the way Sound Forge reports the numbers, that's
all. I don't understand it any better than you, though.

It gets worse....

If I cut and paste the 'active' channel only (from the stereo recording)
into a new 'window', I get 'dual mono' (which actually sounds quite good)
without the strange -6 dB 'limit' thus:

http://www.apah69.dsl.pipex.com/show...no%20Tenor.jpg


If I then try to 'convert' that to mono, it goes into 'Pavarotti Mode':

Well flummoxed now - looks like I'm gonna hafta learn the bloody software
after all....!!

Uh oh, 'shutdown mode' coming on....

Yebbut, do practice turning down until it isn't clipping any more.

The volume on the amp is at 8 o' clock and not loud in the room, the gain on
the preamp is about 20% (if that) of max, the sliders in SF are nearly on
the floor - it records fine (OK, maybe up to 0.0 on the heavy ****, but the
'clip flags' don't come on).....

....and then the fekkin thing clips on playback.....???

Need to get the socket set out, I suspect....

Well, those pics are really heavily clipped. Fire up the windows
mixer, click the advanced button on the mic input and take away the
tick from the 20dB gain box. That should make the sliders and levels a
bit friendlier.

Noop - the recordings are single channel from the mic's pre into my
'computer amp' Aux Input and Tape Out to the computer.

Here's the last batch - A and B are the same setup as Bangs A and B, C and D
are swapped about a bit. The 'dual mono' workaround was employed to avoid
the -6dB SF brick wall (??) and provide two channels of music - with a
little adjustment here and there to avoid clipping, but it wasn't a breeze!!

So.....

Which twin has the Toni..??

Well B and D both have the same problem of a horrifying fizzy
distorted top end, although I have to say that they are all (apart
from the reference) very lacking in bass. If these have been recorded
through the Behringer mic, that is down to the speakers. We also have
the rapid dropoff above 10kHz on all of the speaker files - again, not
down to the mic any more.

So what is it with B and D? I'm actually surprised you can bear to
listen to them, they are just horrible.

Of the four 'system sounds' I would pick 3. Best bottom end.
