I have been searching for an up-to-date HDMI de-embedder over the years. Yet, I am still on a learning curve!
I have learned that there are 2 types of such products:
Some of these hardware (but only if the specific details can be unearthed) appear to extract the audio without 'reconstituting (reconstructing?)' the actual HDMI pass-thru HDMI/video data... during the audio-extraction process.
I am in the hunt for such an 18GB-speed HDMI extractor that provides XLR audio outputs that can match 'CD quality specs'.
I would be satisfied if it is only 2-channels and under ~$400.
Atlona AT-HDR-M2C ($$=??) and
Extron HAE-100 4K ($$=??) come close to my wants.
Prophecy PRO-AudioExt 4K HDR (@ $50), and
Monoprice BlackBird4K (@ $45), and even the
Tripplite P130-000-AUD4K6 ($58) seem better parlays than this tested pos!
I have very little trust in manufacturers specs, now that Amirm is the real sheriff in the audio universe!
