Feature files and directory are hardcoded in the .rb file. Update those lines before running.
Dependencies
Ubuntu. Verified with Xiaodan's 9.04, Camille's 64bit 8.10, Mark's 9.04. 9.1 in progress.
Get security updates. Install packages with aptitude (or apt-get) and gem (some back and forth to discover dependencies):
- aptitude update
- aptitude install sox audacity libaudiofile-dev ruby ruby1.8-dev rubygems1.8 mesa-common-dev libglu1-mesa-dev freeglut3-dev imagemagick libmagickcore-dev libmagickwand-dev (may need to change order; may replace *magick* with libmagick++9-dev)
- From http://rubygems.org/ , install gem from the .tgz file. Follow its instructions.
- gem update
- gem install rake mkrf ZenTest RubyInline rspec rice
(consider sticking to ruby 1.8 for the sake of http://rmagick.rubyforge.org/install-faq.html)
- gem install rmagick --no-ri --no-rdoc (fails on 8.10, imagemagick is too old?)
- gem install ruby-opengl (fails on ubuntu 9.1 and 10.04): http://rubyforge.org/tracker/index.php?func=detail&aid=27386&group_id=2103&atid=8185 )
- Install HCopy and HList from HTK-3.4.tar.gz (register first).
Notes
- locate finds a file on local disk
- apt-file find ruby.h lists packages that generate ruby.h
- alsamixer adjusts volume

Notes
- Audio:
AIT_20061020_AmarkIII_1.ch4.wav
- 92 dims (14 dim decorrelated event-classifier neural network output + 78 dim filter bank parameters):
AIT_20061020_AmarkIII_1.ch4.annhtk
- For each 78 dim filter bank parameters (or MFCCs), the first 26 dims are original, the second and third 26 dims are respectively first- and second-order regression coefficients derived from the first 26 dims.
