These are made on the centre line between your monitors, at ear height, and symmetrically left and right of the centre line at various distances around the optimum engineer’s position. ARC 2.5, like previous 2.x versions, requires at least seven measurements, and can use up to 16. Tests have to be made with an ASIO- or Core Audio-compatible interface using a 48kHz sample rate, and the tones involved can be quite loud, so it’s advisable to use ear protection. The measurement utility is now available only as a 64-bit program, and the process involves five steps.
#Ik arc system 2.5 software#
I will describe new features and show what the measurement software does. Paul White covered ARC 2 shortly after its release in SOS October 2013, so I won’t repeat his basic description, his comments on treating small rooms, or the fact that he found ARC 2 to do exactly as claimed. The new v2.5 software is still compatible with the previous mics, though. This is said to offer improved consistency, for better results across the audio spectrum. Whereas the mics supplied with v1 and v2 were conventional capacitor mics, the new model uses MEMS technology (see box).
#Ik arc system 2.5 upgrade#
The new software is a free upgrade for ARC 2.x owners - you can just go to your account at IK Multimedia and download it - but the headline news is the provision of a different microphone. Although the mics were ‘tailored’ for the ARC application, being capacitor mics they were subject to unit-to-unit variation and drift in frequency response over time. In 2013, ARC 2 was released with added features, better measurement resolution and a new, improved microphone, though users were given the choice of using an older mic if they had one. Advanced Room Correction, or ARC, shipped with a dedicated omni measurement mic and allowed users to measure the frequency response of their monitoring system and apply corrective EQ in a plug-in. IK Multimedia have been developing audio software and hardware for almost two decades, and it’s now 10 years since they introduced their software-based room-correction system. ARC works fine with nearfield monitors, full-range and subwoofer arrangements, and can be switched instantly between different monitor setups.Ī new microphone technology is helping IK Multimedia’s ARC provide ever-better correction for uneven room acoustics. This view shows the calibration for my studio using Equator Audio D5s and a KRK 10S subwoofer. So, if you’re after a great level of accuracy from your monitoring system, make sure to use the ARC 3 MEMS microphone for the room analysis phase.The newest ARC plug-in window looks just like all ARC 2.x versions. The second model was more stable, but even that one is surpassed in terms of precision and stability with environment and age by the ARC 3 MEMS microphone. So, if you own one of the original ring-less microphones that was sold between 20, while you can for sure use and see the results, there are chances that its reliability is not great at today (11+ years later), making the precision of the ARC 3 correction less accurate. In 2009 that mic was replaced with the second model (with the orange ring) to improve the stability with time and temperature. There were two models of the original ARC condenser microphone, one with an orange ring at its base, one without the first model is from 2007 and it’s the one without the orange ring.Ĭondenser microphones tend to vary their response with environmental conditions and with age. With normal “recording” microphones the accuracy of the frequency response down to the dB or fraction of dB is not that crucial, but for measurement microphones it’s a fundamental aspect. However we do have more information on why the MEMS microphone is the best choice:
ARC 2.5 let me specifically identify the mic before corrections. My mic has the orange ring around the bottom.
