/avr:measure

Take a single frequency response measurement and analyze the result.

Arguments

• $ARGUMENTS — optional: target curve name (e.g. "harman") to compare against.

Workflow

Step 1 — Pre-flight

1. Call check_system to verify hardware is ready.
2. If any check fails, report and ask the user if they want to proceed anyway.

Step 2 — Take measurement

1. Call measure MCP tool to trigger a sweep.
2. Call get_measurement_history with limit=1 to retrieve the result.

Step 3 — Analyze

Report the frequency response analysis:

• Bass extension: -3dB and -6dB points (where the response drops off)
• Room modes: Frequencies with peaks or dips > 6dB from the mean
• Smoothness: Standard deviation of SPL across the measurement band
• Overall level: Average SPL in the measurement band

If a target curve was specified:

• RMS deviation from target across the measurement band
• Per-frequency deviation: which frequencies are above/below target and by how much
• Suggested EQ corrections: what filters would improve the match (informational only, not applied)

Step 4 — Compare to history

If there are previous measurements:

• Compare to the most recent measurement.
• Note any changes (better/worse extension, mode changes, level changes).

Step 5 — Report

Present results clearly:

• Use a simple table for frequency response data if helpful.
• Highlight the most important finding (e.g. "You have a 12dB null at 45Hz — this is likely a room mode").
• Suggest next steps if appropriate (e.g. "Try /avr:calibrate to EQ this response to a target").

Important rules

1. Don't apply anything. This skill only measures and reports. Use /avr:calibrate to apply EQ.
2. Be specific. Name exact frequencies and dB values.
3. Explain room modes. Users often don't understand why they have a null at 45Hz. Briefly explain.
