Supercollider Tasks

The ATS Task

Task Name: Set: Due: Weighting: Courses:
CMP Task Summary All CMP tasks

ATS (Analysis-Transformation-Synthesis) files are analysis files created using Oscar DeLiscia, Juan Pampin and Pete Moss's atsa command-line analysis tool (available at http://www.dxarts.washington.edu/ats). The analysis of the sound first attemps to track and record frequency data into sinusoidal partials. Then, any sound that couldn't be analyzed into partial information is analyzed as noise information. The information can then be tranformed and resynthesized using this information. Once installed, type atsa at the command line to see flag options and usage. An example from within the SuperCollider_f directory: atsa sounds/a11wlk01.wav sounds/a11wlk01.ats -H5000 -H5000 limits the analysis to frequencies below 5kHz.

The Task


  • Download the above file(s).
  • Create a 30 second demonstration of the use of the above. Use the following code to record your effort: 

// recording (to the SC directory)...
// use your own path below if you want.
(
s.recSampleFormat = "int16";
s.recChannels = 1; // number of channels
s.prepareForRecord("controllers.aiff");
// use the particular path above...
s.record;
)

s.stopRecording;

Finally

  • Zip or Stuff your patches, demos, etc. into one file called your_student_number_"SCATS" (e.g. 0504335_SCATS.zip or 0504335_SCATS.sit), include a readme with your name and student number and, if necessary, how to use or just open the patch, and submit the whole thing here.

The Projects

The projects and tasks are designed to help you through the various courses and materials that you'll have to deal with, and also to provide an active and practical element to what could otherwise become a rather dry and technical exercise. Tasks are small exercises - you may be asked to complete one or two per week. Projects are larger and carry a higher percentage of the mark. We will undertake two, three, four or more projects and tasks. The final project is usually an individual choice project, and will be worth significantly more than the others in terms of percentages in your portfolio. We will usually try to set aside a time to perform the projects in a public setting.
