GoXLR and Adobe Audition EQ Matching

Introduction

This guide documents my findings from analyzing the GoXLR signal chain using Plugin Doctor to create equivalent EQ settings between GoXLR and Adobe Audition. These notes will help you match settings between both accurately.

Understanding GoXLR EQ Characteristics

General EQ Properties

• GoXLR EQ bands use a normal bell curve (not proportional)
• For matching in Audition, set the bell Q to 1 (instead of Audition’s default Q of 2)
• GoXLR rounds frequency values to the nearest hundred after the first 3 bands
  • Example: Setting a band to 1240Hz will round down to 1200Hz

Low-Pass Filter Behavior

• Recommendation: Set low-pass filter to -5dB at 30Hz for approximately 40Hz 18dB/octave cut
  • This matches standard settings for MixPre interfaces

High Shelf Peculiarities

• Setting high shelf below 8kHz creates an unexpected dip around 4.5-5kHz
• For linear brightness boost, set high shelf above 10kHz
• To boost 9-10kHz range by 2dB, set high shelf to 12kHz +4dB

Converting Between Platforms

Adobe Audition Low Cut to GoXLR

• Set GoXLR low-pass 10Hz lower than Audition’s setting
  • Example: For 60Hz low cut in Audition, use 50Hz on GoXLR
  • Also set to -5dB on GoXLR to match Audition’s default curve

Matching Adobe Audition EQ to GoXLR

• EQ Shape: Set Audition’s Q to 1 instead of default 2
• Remember to account for the high shelf behavior differences noted above to get a proper 1:1
