Of course they are! Otherwise we wouldn't need the lockfree ringbuffer :)

The audio thread is created implicitly by the audio backend. Typically, 
there is only a single audio callback and thus only a single "audio 
thread" per application.

However, an application may create additional helper threads to spread 
DSP computation across multiple course. This is done by most modern 
DAWs. Another example would be Supernova, the alternative SuperCollider 
server by Tim Blechmann.)
