Hi Simon,
Here's a quick and dirty to spectrogram:
There are three dimensions you are interested in for sound:
1) frequency
2) intensity (volume/amplitude)
3) time
Waveform view (what you are used to) only represents time and intensity (you
can glean some frequency info
Any discussion of measuring sound quality by machine needs to contain the
caveat that only a portion of the sound is measured by the machine. A large
part of what we hear is created by our own ears and will not show up on the
graph. Our ears can measure much more accurately than any machin
There are a couple things to bear in mind with software and digital
recording -
1 - The computer does in fact record all that is there. The microphones
act in a very similar way that our ears do. The record all harmonics
and any other pressurization within the room.
2 - You can measure pitch ea

With all due respect, I think this is slightly innacurate. In fact, ALL the
sound is recorded and measured by the mach
Marc, I think we're talking about two different things. What I meant was
that if you have any machine make you a nice graph of which harmonics are being
sounded and how much of each harmonic is present, what is shown will only be a
small portion of what any human being would hear.

I thought that would get a rise. Yeah I splice in something that's OK. I
suppose I could extend the good part backwards. The no-attack being better than
the SPLEAH. A trained ear would hear the patch, but everyone hears the clam.
You can correct pitch, too. I have a CD where I make a grand SPLOOEY.

Then you don't get the development of sound over time. The way it goes
over time is perhaps the most importan
