About Us

We calibrate sound systems to industry standards

We calibrate loudspeakers in rooms to the same industry standards used in professional recording studios. See Standards.

Accurate Sound Calibration using DSP

Calibration is achieved through the use of Digital Signal Processing (DSP) software, and if required, acoustic room treatments. See DSP.

Accurate Sound Reproduction

Once calibrated, the music arriving at your ears matches as close as        possible to how it was intended to sound by the artists. See Testimonials. 

Our engineering process

1) Requirements

3) Solution Report

1) Requirements

  1. Send pics and dimensions of your listening room.
  2. Listing of your audio equipment and description of signal path.
  3. Measure your system and send us your REW .mdat file for a free analysis.

2) Analysis

3) Solution Report

1) Requirements

  1. Initial analysis to determine if measurements fall within operational limits.
  2. Compare measurement to industry standard specs.
  3. Create initial DSP filter and/or acoustic treatment design.
