Post Mortem

You know the track is wrong. You have stared at the same eight bars long enough that the room, the headphones, and possibly the snare have all started lying to you. Post Mortem checks the REAPER track you are working on, shows what it measured, and gives you one practical move when the evidence supports it. Then you can audition that move without committing it.

The paid 0.1.1 early-access release is for Apple silicon Macs. It is signed, notarized, stapled, and delivered through a private download with a unique offline license.

What it reads

Post Mortem reads the selected track’s FX chain, current parameter values, sends, receives, parent bus, fader, and pan. It captures 10 seconds after the FX chain and measures loudness, peak, crest factor, spectrum, stereo behavior, and silence.

The model gets those measurements and relevant project metadata. It does not get the WAV.

What it gives you

The result separates measured facts from the model’s read. It shows one main finding, one suggested move when the proposal can be verified, a confidence rating, and the evidence behind it.

Post Mortem is not allowed to bluff. A Track Check sees one track, so it cannot claim that the guitars are masking the vocal. If capture isolation is not proven, the diagnosis is refused before the model call. If the capture is dead air, it tells you to move the cursor instead of inventing an answer.

Fix Preview

Preview rechecks the track, plug-in, parameter, and current value before it touches anything. It captures the original, tries the proposed value, captures the candidate, and restores the original.

The panel shows the measured change and any safety guardrail that moved. It does not declare the candidate better. You listen and decide whether to apply it. Apply creates one named undo point, so one Ctrl+Z takes the change back.

Version 0.1.1 supports track volume, track pan, FX bypass, and one verified numeric FX parameter. It does not add or remove plug-ins, rewrite routing, edit items, or write automation.

The current limit

The bridge must prove that the capture contains the selected track alone. Item-less routing and bus tracks are supported by the current path. Ordinary tracks with media items may be refused because their render could contain the full mix. Soloing by hand does not count as proof.

That makes the first release narrower than I want. It also keeps the diagnosis honest, which matters more.

Price and access

Early access is $39 one-time. It includes the current Track Check and Fix Preview release, permanent use of version 1, and 12 months of version 1 updates. Mix Check, local Sonic Memory, history, hosted checks, and automatic updates are planned work, not features you are buying today. Version 0.1.1 uses your Anthropic API key or the model in an MCP client, so model-provider usage is separate.

The docked panel, installer, and offline licensing are the paid product. The Post Mortem engine on GitHub and Reaper Daemon remain MIT licensed.

Windows and Linux paid installers stay withheld until their clean-machine customer paths pass. The free engine remains cross-platform for terminal users.

Read the early-access license, support, privacy, and refund terms before buying. If the current scope fits your REAPER setup, the private installer and unique license are delivered immediately after checkout.
