This is what @Amirm from Audiosciencereview says about Digital Room Correction:
"Nearly 20 years ago I had my first experience with room correction courtesy of a now defunct company, TacT. I remember being startled with what I heard. The transformation is incredible. I forever became convinced that room equalization is mandatory in any home system. As soon as I turned on the Focus mode, the (somewhat) boomy bass disappeared, resolution in bass became much higher (allowing individual tones to be distinguished). Soundstage opened up with sound losing its congested character. Everything you think "hifi" is, is applied yet again to your system. You want to sit there and re-listen to your entire library again.
If you have not heard a proper room equalization system, I don't know that you can ever understand the words above. Suffice it to say, nothing, nothing you can do to your system to uplift its performance as much as room equalization can. Why? Details will become obvious in the objective section next but for now, the room gets a hold of the sound out of your speakers and massively modifies the frequency response. Since we are so sensitive to frequency response changes, we hear that as massive coloration."

Licensing:
- The rooDRC license is valid for one device and one customer per license key. All license options are lifelong licenses with no recurring fees.
- Choose the option that best fits your setup:
License Key plus calibrated microphone:
For customers without a suitable microphone. Includes a professionally calibrated ECM8000 microphone ready for use with rooDRC.
License Key plus Calibration File Conversion:
For customers who already own a microphone with a calibration file. Send us your calibration file and we will convert it for use with rooDRC.
License Key only:
For customers who already have a suitable microphone and do not require microphone calibration conversion. - The transfer of the license from one RaspberryPi or rooExtend-Box to another RaspberryPi or rooExtend-Box is always possible by revoking the license on the licensed device and then entering the license key on the new device.
- If the RaspberryPi or rooExtend-Box is physically destroyed or no longer works for any other reason before the license has been revoked, this inevitably leads to the loss of the license.
- Companies are prohibited from flashing the roonExtend image onto SD cards and then selling these preinstalled SD cards.
- Companies are expressly prohibited from bundling a RaspberryPi with such a preinstalled card and selling it as a package. If you are a reseller and have plans in this direction, please contact me at [email protected].
