Update the multi-reverb example with improved transitions
...
This better calculates the environment coverage by correctly calculating the
portal's extents, improves the panning direction when close to the portal, and
applies attenuation based on contribution. Movement has changed to make the
listener move back and forth between environments with a stationary source,
rather than continually looping environments with a position-relative source.

Despite being marked as restrict (and const for src) to mark the pointers as

Avoid using pa_stream_begin_write with PulseAudio
...
It seems to actually have a negative performance impact when the system is
under load. Without having actual measurements for any potential benefits,
simply go with the recommended (and previous fallback) method of allocating
space for the write and passing the free method.
Ideally some kind of ring buffer could be used, so rather than constantly
allocating and freeing blocks of memory, it uses the same memory over again
with the callback marking each one as reusable. Unfortunately the callback
isn't given much information to work with, and the update size (minreq) can
potentially change during playback, which complicates things.
