JOS 320C Project

Goals

  • Make my first "meta plugin" that writes out files for other plugins to read
  • Learn how to make better GUIs for plugin Editors

Plan

  • Look at some 220C projects for general orientation on project reporting
  • Read ahead in the course schedule to learn about GUI options
  • Decide on a file format: XML? Plain text? Encrypted?
    • I am starting with plain text, and planning to include a hash string generated by a secret algorithm to detect modification if/when needed
  • I am now reading all GUI-related JUCE tutorials that are new since I last looked

GUI Prototype

  • JUCE GUI Editor used (very quick)
  • Band-setting sliders will be programmatically laid out dynamically
    • Later planning to draw the T60 curve directly, like many EQ interfaces these days
  • Configured for waveguide string loop filter
  • Can also be used to design late reverb

Project Source

See the jos directory of the 320C-2021 GitLab project which can be cloned as follows:
git clone git@cm-gitlab.stanford.edu:jos/320C-2021.git

T60 Designer Help

  • T60 Designer is an audio plugin that designs, tests, and exports digital filters to other compatible audio plugins.
  • The filter design is specified as the desired decay-time in each frequency band.
  • Decay time is specified by T60, which means "time in seconds to decay by 60 dB" (a term commonly used when studying reverberation).
  • Presently two filter types can be specified:

Test Pluck Help

When T60 Designer is configured to design a "String Filter", then the "Tester" panel in the lower-right corner provides a Pluck button for hearing the sound of a plucked waveguide string using the loop-filter designed by T60 Designer. When you like what you hear, you can Save it out as a Preset that any compatible plugin can use.

Audio Plugin Development Workflow Summary

  1. Throw together a first GUI using the JUCE GUI Editor (design step)
  2. Implement the plugin
  3. Recreate the GUI using Plugin GUI Magic
  4. Develop final image assets for a professional GUI appearance and drop them in
