Is Audius free to use?

I'm curious to know, is Audius a platform that's free to use for all users? As someone interested in exploring the world of decentralized music streaming and cryptocurrency, I want to ensure that there are no hidden costs or fees associated with accessing and utilizing the services offered by Audius. Can you clarify if the platform is indeed free to use, and if there are any limitations or restrictions that users should be aware of when joining the Audius community?
