This component helps to detect and compensate for the unwanted resonances in high-quality headphones and earphones.


  • Corrects deficiencies of room acoustics (multipoint compensation).
  • Corrects acoustic imperfections of speakers.
  • Avoids the pre-echo (pre-ringing) problem of conventional convolver-based room correction systems. The absence of pre-echo ensures the neutrality of the sound.
  • Works in rooms, halls and outdoor venues of any size.
  • Works with zero latency. Perfect for live performances and studio monitoring. Doesn't delay the audio track when playing video.
  • Performs frequency response correction, phase response correction and time domain correction.
  • Quells resonance peaks of frequency response while leaving the deep notches. Avoids the overcompensation which happens in conventional linearizing room correction systems.
  • Manually adjustable level of compensation allows one to reach the maximum transparency of the sound.
  • Supports full range of sample rates from 44,056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in quality.
  • Includes a custom target curve feature.
  • Applies 64-bit signal path throughout.
  • Works with USB measurement microphones (e.g. MiniDSP UMIK-1 or Dayton Audio UMM-6) or standard measurement microphones (e.g. NADY CM100 or Dayton Audio EMM-6).
  • Supports microphone calibration files.
  • Applies a patented method of frequency response correction.
  • Works as a simple conventional mouse drawing EQ if necessary: just load the simple_eq.snr preset and mouse draw any EQ curve you want.
