What is the total supply of Audius?

Can you please explain to me in detail, what exactly is the total supply of Audius? Is it a fixed number or does it vary over time? Are there any factors that influence this total supply, and if so, what are they? Additionally, is there any way to track the current and historical total supply of Audius, and where can I find such information? I'm interested in understanding the implications of this total supply on the value and stability of Audius tokens.
