Wave file analysis

Big City Nights

Don't Let it Bring You Down

Chord changes

I recently upgraded from Audition 1.5 to 2.0. I had tried to run it on
a Pentium III with 512MB RAM and a SoundBlaster PCI soundcard, and it
was not able to deal with the 2.0. I was surprised how even on my new
system (about 4 times the CPU. 4 times FSB and double the RAM) and it
is still slower loading on the new PC than 1.5 was on the old PC.
Whatever, that is only some times an issue. Though I am keeping both
versions installed for now because of how fast I can load and process
quick edits with 1.5. The function is only superior when getting in to
advanced functions. The interface is verynice and reminds me of the
high-end Cakewalk applications. I some times use Guitar Tracks Pro 3
when I want lots of real-time processing for the guitar, but CW3 has
no wave edit features. It only functions as a multi-track application,
which is one of 3 modes for Audition.

Anyhow, I wanted to see if anyone has some ideas on how to do some
advanced analysis with any application. Audition 2 has a "vocal"
remover that works amazingly well to create your own "karaoke" tracks
for jamming with, especially since it also removes the lead guitar
licks. It is called "center channel remover" as well, which is exactly
how it worked on the files I tested it on. In analog sound processing
(Dolby pre-digital Surround Sound processes encoded files by
separating 4 distinct channels, the left and right channels are
augmented by a center channel and a lower quality rear channel, which
in analog processing does not separate left and right for rear channel
info. The Dolby Digital processors separate the rear in to left and
right, and also process the same frequency response and signal-to-
noise ratio as the front channels. In fact, the rear tracks for Dolby
Digital are actually superior to any channel of the analog processors,
because the digital processing has completely discrete channel
separation that even the very bet analog processors can't manage. The
same is true for all of the Dolby Digital processors with only the
subwoofer getting less than optimal frequency response (though one
could say it is optimal for subwoofer, but just not identical to the
performance of the other full range channels).


So all of this is really getting to the idea that I want to try. The
Audition and similar wave editors allow sampling any section of the
track and manipulating it in a number of ways. What I want to find is
a way to sample chords and isolate which chord mode is being played.
There are several tracks that have driven me crazy in the time it
takes with "hit or miss" chords I have tried to figure out. The track
I want to play is Neil Young (and covered on Annie Lennox's "Medusa"
album) called "Don't Let it Bring You Down". The key is "C" but I can
discern the chords and modes that are in the progression. Normally I
would first follow the bass line to get the root of the chord and then
from there I could then figure out what chord and its mode are being
played. This song is not the only one to frustrate me, but it is one
that I want to figure out to use the chord progression in other track
I compose.

Does anyone have any idea on;

A) How to use digital or other tools to solve these questions
B) Happen to know the chord progression in the track mentioned

This would be a great Christmas present to have!

TIA

It looks like a few people have figured it out at least to some
degree. You can probably fill in the cracks if it doesn't sound like
they got it just right.

CLAM will analyze music and show the chords:
http://clam.iua.upf.edu/index.html
Use the 'Music Annotator' and turn on 'view->link current segment to
playback'.
It's somewhat confusing software as it does a lot of other stuff, but the
chord detection is pretty good.

Try Transcribe! from
http://www.seventhstring.com

It's a great tool for transcribing music. I won't try to describe it,
just grab the demo version and try.

One trick for you. It can be hard to tell what notes are in a chord.
But it's easier to tell what notes AREN'T. Loop a section, play
along. You'll easily hear when a note dossn't fit. Eliminate
those....
