Price €239.99
Contact www.ikmultimedia.com


ARC has been around for over 10 years and comes as a DAW-based plug-in that uses Audyssey MultEQ® XT32 patented technology to correct frequency and phase distortions in multiple room points, with additional measurement software that takes up to 16 measurements and features extra resolution in the low frequency range.

Sonarworks Reference 4

Top 11 Products for Room Calibration - Sonarworks Reference 4

Price €249 or €299 with mic
Contact www.sonarworks.com

Reference 4 Studio Edition comes with very easy to use speaker measurement software that takes 37 readings from the room to give an accuracy of +/- 0.9 dB. You also get a plug-in version, plus Systemwide, which runs throughout your entire system audio and is very useful for listening to other music outside of your DAW. We’ve used this on a variety of rooms now and find it to be a fantastic solution.

Dirac Live Room Correction Suite

TRACT is a new piece of software from Waves that’s aimed more at live engineers wanting to balance and time-align a sound system. It uses a corrective FIR EQ curve that can be set to low-latency minimal-phase, or to linear-phase modes, with the ability to select and edit reference curves for the correction.

miniDSP UMIK-1

This USB measurement mic from miniDSP is plug-and-play on Windows, Mac and Linux, so you can go direct via USB. This also means that you can plug directly into an iPad so you can do measurements on the move. The frequency response is 20Hz to 20kHz, and, like the other mics, the UMIK is provided with a unique calibration file base on the serial number.

IK Multimedia MEMS Mic

Price €69 (£61)
Contact www.ikmultimedia.com

IK’s Arc software was updated to version 2.5 last year along with an upgraded mic, which is also available to purchase separately. It’s centered on a omnidirectional, high precision MEMS capsule that ensures maximum response accuracy and stability over time. It’s also extra durable with some very extreme resistance to humidity and temperature variations that can often cause issues.
