Note that the main page of that MPEG-H decoder states that it supports only baseline MPEG-H level 4 profile. But I just gave it a super quick test, it refuses all non-MPEG-H files in its transport decoder. The binary is also 11% smaller suggesting it's missing a lot of stuff.

Oh,  sorry for wasting your time!
It should have been better if they just made it as a superset of FDK-AAC decoder when it's apparently using the same code base.

Hi... After marvelling with Carl's xHE-AAC exhale,
Anyone knows where I can find a Dolby AC4 implementation? My UHD TV includes this codec and I would like to use It.

I took a quick look at exhale sources and I don't see it doing anything to source WAV file channel order. If that's the case @john33 is absolutely correct and multichannel files encoded with it are quite broken, unless manually reordered to correct channel order.
My apologies, you're absolutely right, I totally misunderstood how the extensible WAVE format works regarding multichannel (I thought it allows to reorder the channels... which it doesn't). Just committed a fix to exhale's main branch, along with a minor tuning for the low-rate BA_MORE_CBR modes. With that the channel ordering should be correct.

If I don't reply to your reply, it means I agree with you.

Apologies, I uploaded an AVX2 optimised compile in error for the x64 version. I'll recompile and upload again. Thanks for letting me know.

Playback requires this component in foobar (for 64 bit Windows, otherwise the standard component):

Playback of encoded files with both encoders works fine here.

EDIT: x64 compiles now updated.
