Accurate Sound Reproduction Services

Professional Digital Room Correction (DRC) Calibration Service in 6 easy steps:

1. Measure your loudspeakers in your room/studio – we can help.
2. Send us your measurement file, room/studio dimensions and pics.
3. We design the best FIR DRC filter possible.
4. Load the FIR correction filter into your music player/DAW.
5. We fine tune the tonal response to your preference.
6. Calibrated to industry standards e.g. ITU-R BS.1116-3 and EBU Tech 3276.

Understanding the bass quality issue

Every room suffers from what is called "room modes." This affects the evenness of the sound of the bass.
Some bass notes disappear while other notes sound too loud. The reality is that your room is in control of bass frequencies not your loudspeakers.

As noted acoustician Floyd Toole says, "In the investigation of many rooms over the years, I would estimate that something like 80% have serious bass coloration."
Further, Floyd's research shows that bass subjectively accounts for 30% of how we judge speakers sound quality.

Why our Digital Room Correction service is unique

Our Digital Room Correction (DRC) calibration service is unique as we use the physical dimensions of your room to calculate the optimum DRC filter.

Our science-based approach is to fully correct the bass frequencies, reducing the amount of correction through the diffusion zone, and only correct the direct sound after the diffusion zone. The result is even and clear bass response without changing the characteristics of your loudspeakers.

Additionally, the 3D image is enhanced as the loudspeakers and room response are identical in both frequency and time domain. This also perfects the stereo phantom center image.

What's included:

• Up to 6 custom designed DSP FIR filters tailored to your personal preference for tonal response while taking care of room effects for one system. The process is incremental and iterative.
• All design artifacts including target design, frequency dependent windowing settings, etc. are delivered at the end of the process.
• A short video using your measurements to walk through the analysis, design and filter generation process so that you can replicate was what done. Includes tips and tricks for further experimentation.

We have calibrated over 175 systems from around the world. For more details, please visit our website: https://accuratesound.ca/
