What it is

frZone is a frequency-analysis tool that divides audio into playable or teachable zones. It belongs in the Atlas as both a DSP study and a classroom-friendly way to make audio behavior legible.

What it lets people do

It lets people hear and see how bands, thresholds, and trigger logic turn sound into event streams instead of treating analysis as a hidden background process.

What is public now

• Project repo Current architecture, MIDI map, OSC addresses, and quickstart material.
• Source evidence already surfaced Public repo documentation supports cautious architecture and trigger claims even before a demo capture exists.

Evidence status

Status: working study. Source documentation supports the architecture, but the public page still needs a short capture where audio input, threshold state, and MIDI or OSC output are all visible at once.

Next proof object: 30-second screen recording showing frequency analysis, threshold adjustment, and MIDI or OSC output changing in real time.

What remains unresolved

• The current public page should not claim classroom outcomes or live-rig reliability yet.
• A public-safe trigger log or CSV example would strengthen the teaching and testing story.
• Integration with MOARkNOBS-42, SeedBox, or Horizon should stay modest until directly captured.

Methods surfaced

• Evidence Before Polish A visible trigger capture matters more than a polished plugin claim.
• Documentation as Interface Architecture and mapping docs are part of how the tool teaches.
• Assumption Ledger Thresholds and trigger behavior should stay inspectable.

Proof objects

• Project repo documentation Status: public. Public architecture, mapping, and quickstart material already support cautious structure claims.
• Threshold + trigger screen capture Status: needed. Still needed: one short recording where audio input, threshold state, and MIDI or OSC output are visible together.

• MOARkNOBS-42 A control-surface companion for making the trigger grammar playable.
• Horizon A neighboring DSP branch where listening evidence also matters.
• live-rig A scene system where frZone can become one analysis layer among several.

The Atlas is the relationship layer. Use the repository for current project-specific truth, and use studio-notes when methods, decisions, or teaching material need to travel across the fleet.

Where to go next

• Open MOARkNOBS-42 — See the control surface that can feed or accompany this analysis branch.
• Open live-rig — See where this kind of trigger logic can leave the lab and enter a scene system.
