What you get

  • Live RTA with red bands for cuts, blue bands for boosts, and a target curve.
  • Built-in pink-noise generator to excite the system.
  • Log sine sweep and estimated RT60 room-decay measurement.
  • Suggested per-band EQ changes and export, including a miniDSP / parametric PEQ block.
  • AUTO correction, MANUAL per-band calibration, or FILE calibration using compatible UMIK-1, iMM-6, and REW files.
  • Configurable band count and center frequencies, target tilt, smoothing, and mic source; a 13-band default.

Quick start

  1. Grant microphone access and select a suitable mic source.
  2. Set the band layout to match your equalizer and choose the target curve.
  3. Choose the calibration mode; import the correction file for your measurement microphone when available.
  4. Measure from your listening position using the source you want to tune. Pink noise helps reveal broad response differences.
  5. Make modest EQ changes, measure again, and compare several positions. Export the settings when you have a useful result.

Controls

START begins measurement. PINK provides test noise, HOLD freezes a reading, SWEEP runs the response/decay test, and MENU opens setup. Use the calibration controls and EXPORT for the corresponding workflows.

Questions before you buy

Does it apply EQ to my speakers?

It measures and recommends settings. Apply the changes to your head unit, DSP, receiver, or other equalizer.

Can a phone replace a calibrated measurement system?

Results depend on the microphone, calibration, position, noise, and playback chain. Treat phone readings and RT60 values as hobbyist estimates.

Can I use my own mic calibration?

Choose FILE and load a compatible calibration file, or use MANUAL to adjust bands.
