Some random foss apps Im trying to find

Im trying to find a few different softwares

1. screen recording and/or streaming (preferably lighter weight)

2. Soundboard and other goofy audio stuff

Me and a few friends run some small low quality shitpost gaming channels and I thought it would be funny if I could just randomly chuck sounds in chat and make it a bit more shitposty. We have a lot of fun with it and don’t care for the views, just post for us.
