Summary of the Process

1. Calibrate the SPL Meter

2. Make a Measurement

3. Apply Smoothing

   • Choose Graph: Apply Smoothing 1/24 Octave Smoothing

4. Click the big "EQ" Button

5. Setup a Good EQ View

   • Configure EQ View (Click the "Config" wheel):
     • Smooth 1/24
     • Check Fill Filter responses
     • Uncheck the rest

6. Set the Following Before Generating EQ Filters:

   • Equaliser: Generic
   • Target Settings:
     • Speaker Type: Full Range
     • LF Slope: 24 dB/Octave
     • LF Cutoff (Hz): 10
     • Target Level (dB): 75.0 (or 80)
   • Filter Tasks:
     • Match Range: 20 - 10,000 Hz
     • Individual Max Boost: 12 dB
     • Overall Max Boost: 9 dB
     • Flatness Target: 1

7. Match Response to Target

   • This creates an inverse EQ filter for the VST EQ plugin preset.

8. Export the EQ Filters

   • Go to "EQ Filters" view → Click the double arrow to sort filters low-to-high → Export as Filter Settings as Text.

9. Run "REW2EQPreset" Tool

    • REW RTA Setup Guide
    • Choose dB (Not dB Full Scale)

RTA Configuration:

• FFT Length: 65536
• Averages: Exponential 0.94
• Window: Rectangular
• Max Overlap: 93.75%
• Update Interval: 1
