Positive Grid BIAS Repli-Q – No Longer Available

Professional EQ & spectral matching/balancing plug-in (Mac/PC)
MFR# 667-100-012-892

Product Description

Bias Repli-Q analyzes and matches the frequency content in different audio tracks, so their tonal qualities can be made to sound more alike.

An album may contain tracks that were recorded in different studios, and by different engineers — and they may not work together as a group.

Repli-Q's advanced linear-phase spectral matching takes the best spectral qualities of each track, and applies them to the others — making all the tracks sound like they're from the same studio.


  • Match spectral characteristics of multiple recordings
  • Analyze and apply a favorite artist's spectral "style" to your own recordings
  • Create and apply spectral profiles of studio hardware — consoles, microphones, etc
  • Improve an improperly equalized track with linear phase precision


This professional cross-platform EQ & spectral matching tool includes Audio Units, RTAS/AudioSuite, and VST plug-in formats, so it can be used within most popular professional audio editing hosts on Mac & Windows systems — such as Peak, Digital Performer, GarageBand, Live, Logic, Premiere, Pro Tools, Sonar, Sound Forge, and many others.

  • G4, G5, or Intel-based Mac (≥500 MHz processor)

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
