@joey.landara ah that explains it! No plugins are part of the course as such. You are provided with an Adobe Audition template presets. So you don’t install them as plugins. Here is how to save them as part of your template: Saving Presets as a Template
You may also find it helpful to watch the videos and perhaps read the forum here: Presets - Q&A - Audio Enthusiasts Community - Adobe Audition - Audacity
Let me know if you have any further questions!
