chord detection/recognition software
All -
I have come across what I believe is a very useful aid to identifying chords in recorded music.
The primary product is sonic visualiser, used with its (vamp) plug-in chordino; http://www.sonicvisualiser.org/download.html and
http://www.vamp-plugins.org/download.html,
respectively.
The primary advantage to using these products is that they are gnu/free software foundation supported, which, as the name implies, means that they are free to non-commercial users (I may be wrong about the exact terms under which use is free).
Notes for Windows users.
1. Create folder C:\Program Files\Vamp Plugins. Download the plug-ins in their zip-file packaging and move the files to that directory. Do not leave them in the folders that were zipped or they may not be recognized.
2. I was initially frustrated that Sonic Visualizer appeared not to recognize the plug-ins. On a hunch, I loaded an mp3 file, tried again, and it worked. So apparently, an audio file has to be loaded in order for the plug-ins accessed from the "Transform" pull-down menu to be enabled.
This software isn't perfect, but I've tried it on a number of songs that had been frustrating me and was pleasantly surprised by the usability of the results.
The chords are displayed at the top of the frequency spectrum. I've not yet figured out if there's a way to generate a list of chords in a more concise format, but I'm working on it and will let you know when/if I succeed.
There are other (commercial) products out there and I may try them, but since this took zero $ and very little time to get to where I am now, I think it's worth climbing a little higher up the learning curve before trying anything else.
Hope you find this helpful.
Addendum:
Right after I sent out this message, I determined that a list of chords and time points within song can be produced using the Data Editor window. I've included a screen shot, but the relevant help item can be accessed from http://www.sonicvisualiser.org/doc/r...en/#dataeditor.

The difference between theory and practice is smaller in theory than it is in practice. anon
