Uncommon for audio software, dtas is implemented in Ruby. The latest stable release of Ruby is recommended, currently 2.0.0-p247. However, Ruby 1.9.3 should work, too. Older versions of Ruby are not recommended. SoX is a dependency of dtas-player. While not _strictly_ required, the dtas-player uses SoX by default and you will need it unless you've reconfigured dtas-player to use something else. mp3gain is required if you use ReplayGain with MP3s If you only intend to use dtas-cueedit, you will need metaflac(1) from the FLAC package. Debian users can install sox, mp3gain, and flac dependencies easily: apt-get install sox libsox-fmt-all mp3gain flac = installing dtas RubyGem on GNU/Linux (Linux kernel 2.6.32+) Be sure to have Ruby development headers and a working C compiler. This will pull in the io_splice and sleepy_penguin RubyGems for minor speedups. If you cannot be bothered to have a development environment, just use "gem install dtas" gem install dtas-linux This should pull in the "io_splice" and "sleepy_penguin" RubyGems For future upgrades of dtas (upgrades to dtas-linux will be infrequent) gem update dtas = installing the dtas RubyGem on non-GNU/Linux or old GNU/Linux systems gem install dtas = installing dtas via tarball and setup.rb Grab the latest tarball from our HTTP site: http://dtas.80x24.org/2013/dtas-0.0.0.tar.gz $ tar zxvf dtas-0.0.0.tar.gz $ cd dtas-0.0.0 $ ruby setup.rb GNU/Linux users may optionally install "io_splice" and "sleepy_penguin" packages: io_splice - http://bogomips.org/ruby_io_splice/ sleepy_penguin - http://bogomips.org/sleepy_penguin/
