The converter doesn't just require an output format call, it also
requires this input format change callback to actually signal it to
reopen the converter process with a new format setup.

Output format mostly requires stopping and restarting the output device,
and this also prevents us from using the latency function properly,
which apparently always returns 0 for output devices anyway. These
changes also prevent the output callback from hanging when resets occur.

Fixes visualization latency under virtual machines, at least. Not sure
which local or native systems would be reporting high latency here, but
this should fix them as well.

Move the DSPs to the output node, so they don't get closed and reopened
across each file. Also restructure the output handler to buffer a little
on its own, to account for track switch activity.

The filter uses a pre-buffer of input audio, so extrapolate from the
actual input to fill the buffer. Fixes clicking on non-zero-crossing
track endings.

Buffers were being treated as empty before they were actually processed,
due to races between the current node's end of stream marker and
actually feeding the output buffer.

This was attempting to retrieve the NSURL host object, possibly on a

There is a race condition with the next Node in the chain and the End of
Stream marker, considering how tiny the buffering is for these DSPs. Set
End of Stream instead after inserting the end of stream flush chunk.

DSPs should not be performing a cascading reset when resetting just
their own buffers, for example, on init or shutdown of just that one

Cleaned up project settings to current defaults, except for the macOS
deployment version, which is still 10.13. Cleaned up a lot of headers
and such to include with angle braces instead of double quotes. Enabled
build sandbox in a lot of places. Disabled subproject signing in several
places, for libraries and frameworks which will be stripped and signed
when they are copied into place in the final build.
Also, while trying to solve compilation issues, the visualization
controller was reverted to the Objective C implementation, which is
probably faster anyway. Stupid Swift/Objective-C language mixing issues.

other operations. Audio output changes should also mute and destroy the
buffers of the input chain, so that the audio resets properly.

Now buffer twice as much audio as would be requested for a single
visualization PCM/FFT chunk, which should hopefully prevent it from
flickering due to running out of audio because of too low latency.
Now it buffers up to two chunks at the current hard coded visualization
sample rate, which works out to about 186 milliseconds.

We implement this function to return the current latency buffered,
regardless of how often this function may be called. In practice, it is
only called on track completion, to time the reporting of the next track
display. We also avoid using Rubber Band's latency function, as in most
cases, this function will be called from other threads, and also, it
currently only gets called after Rubber Band has been emptied out, so it
would otherwise calculate zero samples buffered. And thirdly, Rubber
Band's latency function doesn't account for the buffered samples already
removed from it and waiting to be fed out.

The code was polling the input chunk duration after emptying out the
chunk's samples, which resulted in an input duration account sitting at
exactly zero, so the end overrun flush would not be cut short properly,
resulting in gaps between tracks.
Correct the input sum to tabulate before emptying the input chunk, so
output remains properly gapless.

Check all audio chain elements for allocation failures, and also dispose
of all of the previous handles in reverse order, including nulling the
final node handle so the output does not attempt to poll for audio while
the chain is being rebuilt.
Also set up output node to handle the new null finalNode state, and
return an empty chunk to the caller.

This should be perfectly safe to use in all situations now. It may have
been unstable due to mishandling return values, or not supporting
requesting more sample data from the library without feeding in more
input first.
Also, still signaling the End of Stream flag on chunk reading should be
correct, as downstream processors only react to it when the buffer runs
empty.

The Downmixer wasn't updating its output format correctly, so it was
prone to outputting the wrong format for a while, which could confuse

The delay value should be scaled by the resampling ratio, similar to
how it already is when allocating the impulse buffer. This went
undetected, as it scribbled over other memory without causing immediate
crashes, but instead later heap corruption.
