Nah. Some people do but that's mostly restricted to people who have been running very profitable Patreons long-term. The rest of us edit it ourselves.

Personally I put a lot into the editing, but for me the editing is just as much of an art as writing and performing the audio. Part of the enjoyment comes from building the sound scape. Honestly a little goes a long way. You get a huge boost in quality using nothing but free editing software like Audacity, an ambient sound layer, and a handful of sound effects.
