Any indie hackers working on social audio apps?

So much action in the audio space recently...I've been playing around with TTYL's app - http://ttyl.social/ - which Facebook just essentially cloned in their new CatchUp product.

Clubhouse with 1000 users and a $100M valuation...wild.

Any indie hackers working on social audio apps? I'm way into this space as both a builder and user - would love to test out new products.
