REW Measurement Analysis
What is it for? Measure your room and speakers with REW (Room EQ Wizard) and a calibrated microphone, save with File → Save all measurements and upload the .mdat file. You get a report on level and timing, room modes, speaker-boundary interference (SBIR), early reflections, reverberation time (RT60), waterfall, and subwoofer integration, with concrete recommendations.
How to measure
- Use REW with a calibrated USB microphone (Umik-1 / Umik-2 etc.) and load its calibration file. Put the microphone at ear height at your listening position, pointing at the ceiling (90° file).
- Measure each speaker separately (left, right; subwoofer and other channels if any) with the sweep, at about 75–80 dB. Use an acoustic timing reference if you can.
- Name the measurements after the channels (L, R, C, Sub…), save them with File → Save all measurements and upload the .mdat file below.

What is in the report?
- Frequency response of every channel with the room’s transition (Schroeder) frequency and bass deviation.
- Room modes and their match with your measurement; speaker-boundary interference (SBIR) and where to move speakers.
- Early reflections, reverberation time (RT60) per octave and waterfall / decay.
- Level, distance and timing between channels; subwoofer crossover and phase.
- A prioritised list of recommendations (placement, treatment, settings).
Frequently asked questions
Which file do I upload?
The REW .mdat file saved with File → Save all measurements. One file can contain all channels.
Do I need a calibrated microphone?
Yes; without a calibrated microphone the high-frequency results and absolute levels are not reliable. Umik-1 / Umik-2 or similar USB measurement microphones work well.
How much does it cost?
The first report is free for followers of our YouTube channel or Instagram. Each further report uses 1 credit; if the analysis fails the credit is refunded.
