I have forked this player to continue maintaining it for others to use, as its original author appears to have left it by the wayside. I will try to continue updating as I find more things that need fixing, or if I find new features to add which seem like they would be useful to me or others.
Up to date binaries will be available at the following link:

You will need to run the following to retrieve all the source code:
git submodule update --init --recursive
Setup your DEVELOPMENT_TEAM like described in Xcode-config/Shared.xcconfig to build the project.
(Add 2022-05-22) Also, be sure to configure the hooks path, so you won't accidentally commit your team ID to a project file:
git config core.hooksPath .githooks

I've added an HRIR convolver, based on the HeSuVi HRIR format. A preset is bundled with the app, but external presets may be selected, in either RIFF WAVE, or Wavpack format, 7 or 14 channel, 32 bit floating point. A bad or missing preset will fall back on the built-in preset. The settings dialog won't let you assign a bad preset, either.
The channel layout of the HeSuVi HRIR is as follows:
I altered this image from the original on the HeSuVi HRIR developer readme, as their image incorrectly swapped the left/right output order for the right input channels, which are actually supposed to be right output first, then left output. Otherwise, if observed as the original image, all output comes from either the center or the left side.
The layout for 7 channel no-reverb presets is the same, except it only includes the first 7 channels of the layout, and the opposite speakers simply mirror their respective input channels, and the center input is used for both left and right outputs.
Here are some preset HRIR files.
The original HeSuVi project is located here.

I've replaced the resampler with libsoxr, with no quality control settings exposed.
ADDENDUM - 2022-03-03
I've replaced the resampler yet again. This time, with R8Brain, using the 24 bit preset, since the player doesn't go over the depth of 24 bit integer or 32 bit floating point, and outputs 32 bit floating point. It still processes the resampler in 64 bits, though.

It has come to my attention that my recent commits may have assumed that Aleksey Vaneev, and possibly any other Russian or Belarusian people are in support of the war in Ukraine. I did not intend to make that assumption. I know that a lot of people are either against it, have family and/or friends affected by it, or in some unfortunate cases, have the wool pulled over their eyes by the local propaganda machine. The only thing I knew at all, was comments to the effect of him being anti-vaccines, which is a bit of a sore subject with me. I do not know anyone personally who has died from COVID-19, but I do support using the greatest caution to avoid it, including vaccines, and masks, and social distancing. I will maintain my fork of the library in case anything happens to upstream, and keep an open mind for now, I hope. Hope this long winded mess finds my users well, and doesn't further piss off anyone.
