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
• Configured for waveguide string loop filter
• Can also be used to design late reverb

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:
  • String Filter (loop filter used in a digital waveguide string model)
  • Late Reverberator (feedback filter used to simulate air absorption in an acoustic wave propagation model)

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
