Audio Enhancement Plug-In

iQfx is a family of plug-ins for the RealNetworks players: RealPlayer, RealOne and RealJukebox. These plug-ins were created by QSound Labs and incorporate proprietary digital signal processing algorithms. The foundation feature common to all versions is a stereo sound stage enhancement called QXpander that, according to company claims, proportionately expands the perceived width of the stereo image without undue sonic coloration (e.g. inherent bass and/or volume boosts) and without weakening the critical signal components such as vocals and bass instruments that are normally placed in the center of the mix.

Version 1

The first plug-in version was simply called iQfx, and was developed from the company's stand-alone consumer software product, iQ. iQfx featured:

  • QXpander 3D stereo expansion (for speakers) with a manually or automatically enabled pre-processor for mono content having music and voice modes, and
  • QBass(TM), a static Bass Boost feature.

    • Version 2

    iQfx2 had two versions: Basic, with limitations, and a Plus version available for a small cost. It contained several new features:

  • QXpander headphones mode
  • Variable QBass input gain
  • QXciter(TM) spectral enhancement with variable frequency, input gain and boost controls
  • QVerb(TM) reverberation simulation with several preset environments

    • Version 3

    The current version of iQfx is iQfx3. iQfx3 features include:

  • RealPlayer-like interface
  • QXpander for headphones or speakers
  • advanced QBass controls - input gain, frequency and boost with increased range
  • advanced QXciter controls - input gain, frequency and boost with increased range
  • QVerb reverberation simulator with six simulated environments and level control
  • Factory and user-programmable presets to save and recall snapshots of all effect settings
