Optional ReadonlyalignINPUT ALIGNMENT delay, ms — the input-stage latency that pushes this microphone back to meet another on the same source. Persisted because a show that restores without it comes back COMBING: the operator aligned two mics, the desk forgot, and nothing says so.
Optional ReadonlyalignWHICH channel this one was aligned against — the record the next operator needs to check or redo the alignment. No audio consequence of its own.
Optional ReadonlydigitalPlain digital gain (dB) — a channel with no analog head-amp. See ChannelSnapshotJson.digitalGainDb.
Optional ReadonlyheadThe BOX's head-amp GAIN in dB — a head-amp channel's captured gain. See ChannelSnapshotJson.
Optional Readonlypad−20 dB analog pad ahead of the box's preamp.
Optional ReadonlypanOptional ReadonlyphantomOptional ReadonlypolarityOptional ReadonlytrimDigital input trim in dB (composes with the channel's gain — see ChannelStrip.trimDb).
One channel's processing captured for reuse: its plugin chain (ordered plugins + params + presets) + channel processing (gain/trim/pan/phantom/pad/SENS/polarity). Stored channel-agnostic so it can be applied to any channel. Borrows MOD-UI's preset round-trip (enumerate / default / mark-current / save user bundle).

digitalGainDb/headAmpGainDbsplit as ChannelSnapshotJson — a retiredgainDborsensDbuhere is exactly as ambiguous as on a whole session and gets the same loud, never-reinterpreted treatment at apply time.
