Without a channel mask, the channels are treated as "raw" or unknown. Auto-
detection will only go up to stereo (assuming the first two channels are front-
left and front-right), while explicit requests will work as long as there are
enough channels (the user is responsible for ensuring a correct setup).
So that it's tried before sndio. Many Linux systems seem to have libsndio
installed as a hard dependency from SDL2, but not the server component to
actually make it work. And because there's no way to test if it's usable
without opening a device, the backend would get selected over ALSA and
subsequently fail to work. As a result, Linux users that don't use PipeWire or
PulseAudio would have to explicitly configure for ALSA.

The write vector represents the chunks queued for OpenSL, and the write pointer
only increments when OpenSL fills in more samples. So requeueing from the start
of the write vector is requeueing chunks that are already queued, which is
obviously wrong. It instead needs to queue chunks that become available as
they're read.
Because the ring buffer holds more elements than can be written to at a givem
time, the read vector does not represent the next writable chunks to queue.
Advancing the read pointer increases the number of writable elements, so
instead of queueing from the read vector or the start of the write vector,
queue from the end of the write vector given the number of chunks read.
There's apparently no way to get the containing class/struct type from a static
member function, and operator new/delete are implicitly static member functions
so the macros to define them need to be told the type to allocate for. This
ensures the type specified matches the containing type.
We want to resample before minimum phase reconstruction since that changes the
phase relationship of the sampled signal, introducing a slight bit of noise
from truncated sampling. It's not clear that the frequency domain resampling
method is accurate, so resampling prior to frequency analysis is an alternative
to ensure the resulting frequencies are given the proper phase for sampling.
This also cleans up some micro allocations in loops.
Currently it makes the pkg-config file unusable as prefix is specified twice.
FULL variables do the necessary parsing and automatically prepend the prefix if needed.
