Getting and Using Vamp Plugins / Get the Chord sequence from a song

« on: October 06, 2009, 13:27:04 »

Hi All,
I'm trying to get the chord sequence for a song.
For this task i'm using vamp:qm-vamp-plugins:qm-keydetector:key since from their Doc they state

"Key Detector analyses a single channel of audio and continuously estimates the key of the music by comparing the degree to which a block-by-block chromagram correlates to the stored key profiles for each major and minor key. "


I'm starting with a simple song, with clear, acoustic guitar changes (Wish you were here, Pink Floyd) but the results I'm getting are not encouraging: both the sequence and the timeline for the chords are quite wrong.

I'm quite new to the field so i'm probably doing something wrong here.
Or maybe there are some better Vamp plugin for the job out there...

Thanks
Frank Danieli
