Matthias Mauch MIREX Submissions 2010

=====================================

This README file contains instructions to run three different methods:

1) chord estimation with a DBN (doChordID.sh)

2) simple chord estimation (doChordID-simple.sh)

3) structural segmentation (doSegmentation.sh)

Each method is called through the respective bash script.

All methods use Sonic Annotator. A Sonic Annotator binary for 64bit Linux is in this directory. Please contact me (mail@matthiasmauch.net) or Chris Cannam (chris.cannam@eecs.qmul.ac.uk) if you need a different version.

All methods use just one core, as far as I'm aware. Whatever MATLAB does implicitly I don't know.

Please find more detailed information on the individual methods below.

1. Chord Estimation with a DBN

------------------------------

Example call to the bash shell script "doChordID.sh":

  ./doChordID.sh wavfilelist.txt outputdirectory

This method requires MATLAB.

This method uses a lot of memory (expected up to 17GB for long songs).

Expected running time is roughly real-time for most songs +/- 40%.

2. Simple Chord Estimation

---------------------------

Example call to the bash shell script "doChordID-simple.sh":

  ./doChordID-simple.sh wavfilelist.txt outputdirectory

No special memory requirements.

This method is quite quick, takes roughly a third of the real duration.

3. Structural Segmentation

--------------------------

Example call to the bash shell script "doSegmentation.sh":

  ./doSegmentation.sh wavfilelist.txt outputdirectory

This method requires MATLAB.

No special memory requirements.

This method is quicker than real-time, takes roughly 70% of the real duration.
