I used AI to analyze my own legally purchased/owned recordings. These seem right to me but feel free to message me privately if you want more details or to collaborate etc.

I didn't want stuff lost but i'm sure @txus could probably do a better analysis then me fumbling through it with AI so if you do end up doing it feel free to replace these whenever you get time. this at least unblocks me so i can hopefully use farfield in the other repo that needs these presets that were missing. :)

Thanks for this, and for writing up the older FLAC so carefully. I've pushed one commit on top (b620183) so the PR could go in. Here's what changed and why.

The build was failing. tests/test_presets_library.py checks the preset directory against an exact list of names, so any new preset has to be registered there. That's done now, and the full suite passes (563 tests).

New best-effort fidelity tier. All three presets were tagged measured-tape, which in this repo means "measured from the original tapes by farfield, with data in docs/tape-analysis/". None of that applies here, so I added a tier for presets that approximate a recording without farfield having verified them. It sorts between "from the patents" and "original designs", and farfield list / describe show it as best-effort reconstruction (unverified). That gives the project a proper home for reasonable guesses, and lets us take these in without overstating them.

Titles and notes. The numbers are untouched. I gave each preset its own title (the two newer ones shared one) and rewrote the notes to say what is claimed, what was set by ear, and what the single 30:00 hold leaves out:

• focus-11-gamma-pink: notes that the 40 Hz SAM claim, if it holds up, would be the first SAM found in any recording. The MSS remasters came back SAM-absent. Also two observations: the carriers sit within 0.01 Hz of a C-major triad at A = 432, which strongly suggests real, deliberate tones, and the depths imply interaural delays of about 550 to 590 µs, a bit beyond the ~510 µs head model.
• focus-11-gamma-theta-pink: says the 175/179 pair is intermittent in the source but plays continuously here, so it's an arrangement. It points readers to the pure SAM preset as the closer match.
• focus-11-older-flac: mostly your text, reframed as contributed and unverified.

I also updated sam-gamma.yaml, which said SAM appears in no measured recording, to mention your claim, and extended NOTICE and the README for the new tier. File names are unchanged so nothing downstream breaks.

The way to promote these to a measured tier: run farfield's own analysis (farfield.analysis, the mid/side complex projection that separates phase modulation from amplitude panning) on the 16:00–27:00 window and share the JSON output. If the SAM shows up, that's a real finding and we'd publish it under docs/tape-analysis/.

A small thing: open-consciousness-functions' docs/BACKGROUND_AUDIO.md says the contribution "has since landed" with "22 Farfield session presets… byte-identical to upstream 0.1.0". After this merge upstream has 19, and the three Focus 11 files now differ from your mirrors, so that passage is worth a refresh.

Merging now, as a squash with you as the commit author. Thanks again!
