This should also seal up any potential hole for problems if there's an
audio format change and no audio buffered.

readAudio now returns an AudioChunk object directly, and all inputs have

Apparently, Apple's Spatial Audio processor doesn't really support weird
configurations like this. So we need to filter them down to stereo.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
This filter replaces the old one, and uses OpenAL Soft presets. Since
there aren't that many of those, I've left off configuration for now,
except to turn it on or off.

Remove a single .inc include from CogAudio build phase, as it's included
but not compiled as Pascal like Xcode thinks. Also remove a bunch of
files from being copied into the resulting .framework and .bundle files
during link stage, as we don't need to distribute that stuff.

The deinterleaved format was being specified incorrectly. Now it asks
for the correct format, which is deinterleaved, and the bytes per frame
or packet sizes are relative to a single channel's buffer, not all
buffers. Oops, that could have been more clear in the documentation.

Equalizer was copying the output of the equalizer repeatedly to the
first output channel, instead of copying each channel correctly. This
had the effect of making the equalizer output adjusted audio to only the
left channel in stereo output, and possibly render the stream sounding
weird.

When restarting playback on the current track, restart the correct

correctly track the play count of the last played item in the play queue
which stops with bufferChain set to nil, so the previous iteration was
not tracking it.

Now the API makes both PCM and FFT data optional, and will do nothing if
neither are requested. Also, it now supports a latency offset in seconds
with floating point precision. The two built-in visualizations currently
request zero larency. Increasing the latency asks for even older samples
while specifying a negative count requests samples from the "future"
relative to what the listener is hearing.

If upsampling the audio by a significant factor, it may be necessary to
process more than one buffer at a time, rather than lose input.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
The visualization buffer now holds up to 45 seconds of loop, and the
latency measurement code now caps this at 30 seconds, and restarts the
output if latency exceeds 30 seconds, such as if a sound output is
reset.

For one thing, the example code I followed was Swift and handled auto
releasing handles in the background, while Objective-C requires manual
handle reference management.
For two, there was no autoreleasepool around the block handling the
input audio chunks, which need to be released as they are pulled out and
disposed of. This also contributed to memory leakage.

The output now uses AVSampleBufferAudioRenderer to play all formats, and
uses that to resample. It also supports Spatial Audio on macOS 12.0 or
newer. Note that there are some outstanding bugs with Spatial Audio
support. Namely that it appears to be limited to only 192 kHz at mono or
stereo, or 352800 Hz at surround configurations. This breaks DSD64
playback at stereo formats, as well as possibly other things. This is
entirely an Apple bug. I have reported it to Apple with reference code
FB10441301 for reference, in case anyone else wants to complain that it
isn't fixed.

Redesign the code signing from the ground up. Now all bundles and their
embedded frameworks import the Shared.xcconfig file and enable its
settings, so they may be signed with Apple Development instead of sign
to run locally. This apparently isn't necessary for frameworks which are
embedded in the main app bundle directly, only for the bundles and their
frameworks.
