Hi Syd
Good to hear from you mate, how's that bloody sunshine down there you stole
from us up here?
Some of the loudness can be dealt with Syd but not the distortion. If you
can load the sounds into your computer and if you have it, use the envelope
facility inside the program?
I'm not familiar with waves Q10, so if I babble on, just delete this now
mate :)
I use Adobe 1.5; surely your program will have wave editing?
Very often I find myself turning up the level to the max in quiet areas and
then BANG a plane or a scream yells out and distorts the recording. When I
get the recording home it sounds up and down as you would imagine and
probably have done so yourself.
What I do to minimize the loudness is highlight the whole area that is
distorted or too loud and affectively, "turn down" the volume.
If you know where your envelope program is, (in Adobe it is in the effects
menu and then amplitude then Envelope)
Using the time on the waveform, I can compensate inside the envelope progra=
m
to whatever percentage I want by dragging the control points.
I don't believe there is a real way to filter out distortion, but sometimes
lowering the volume this way would help you identify certain sounds.
There is another excellent program out there called Soundsoap
<http://xserve1.bias-inc.com:16080/products/soundsoap/> that will do this
automatically. Works with PC and Mac.
Hope you and the missus are keeping well and the lyrebirds and singing thei=
r
heads off...
Take care mate

Subject: [Nature Recordists] noise reduction-parametric eq. RFI
John Hartog (Mon, 29 Nov 2004 21:38:45 -0000) described how he went about
reducing unwanted noise using a parametric equaliser function of Cubasis
VST. Even I could follow his explanation, and I'm very non-technical.
Thanks John.
That encourages me to try a bit harder to use the program I've got, which i=
s
Waves Q10. It has what I take to be an excellent parametric equaliser.
However, right now I have a problem which I suspect is not amenable to the
procedures John has described, and maybe there is no solution, but I'd be
grateful for advice from this so-expert group ... even if only to confirm
that there's no fix.
A friend has some analogue audio cassettes of his father reminiscing about
his experiences as a radio operator on ships early last century.
Fascinating material, but unfortunately the tapes were made with the
recording level way too high, and severe distortion has resulted in some of
it being unintelligible.
There's some background noise which I can probably deal with. And if I
can't, my good friend, Vicki Powys, has offered to help. But is there
anything that can be done about the overload distortion?
I would be extremely reluctant to take these unique tapes away from my
friend's residence, and therefore I have copied one by playing it on my Son=
y
Walkman WM-DC cassette recorder and taking the line-out to a Tascam DAT
recorder. The Walkman in play-back mode shows the recorded level of the
signal and this often went over +5 dB, which is why I fee reasonably
confident the problem is overload.
Any advice would be welcome.
TIA
