Hi! I’m Sam, lead designer of Shasta. You can check out the app at https://shasta.adobe.com (OP's post links to one of our launch announcement pages). Our enhance speech and mic check features are already available for everyone to try.
Buuuut in the meantime, we launched two of our AI features as standalone mini apps that anyone can use for free, and those are called Mic Check and Enhance Speech. They’re fun, try them out and let me know what you think.
