Besides selling courses and audio products individually, I also sell lifetime memberships. The lifetime membership has a significant advantage over the monthly membership.

Once you become a Lifetime Member, you can access all my courses and tools for free. That includes the current courses and future courses.
I currently have five courses:
Audacity for Beginners
Advanced Audacity for voice editing
Podcasting with Audacity
Adobe Audition for voice editing
Audio Clean up A-Z guide
I also have several 1-click sound better and repair tools. These are macros in Audacity and Presets in Adobe Audition.
I suggest you visit the following shop page to get an idea of what tools and courses I have
