IK Multimedia ARC System 4 v4.0.1 U2B Mac [MORiA]

An all-new listening experience
ARC 4 uses a brand-new and more natural analysis and correction algorithm that delivers results you can’t find in other digital room correction systems. By measuring your room across a 3D space around the listening position, IK’s award-winning VRM™ (Volumetric Response Modeling) technology creates a 3D snapshot of your room, identifying problematic issues without over-processing the sound. You have the choice of going through a 21-point ultra-accurate measurement process or a 7-point quicker one. Both will sound great. The longer measurement is more adequate for fixed installations and permanent setups, while the shorter measurement is ideal for on-the-go or ad-hoc setups, making it possible to measure the room in less than a minute.

Measure quickly and precisely
Just connect a measurement mic to your interface and launch the step-by-step room analysis software. You’ll be guided through a series of measurements across your listening position, and with ARC’s flexible placement options you can create measurements of multiple monitors and listening positions, so you can virtually adjust the sweet spot for clients or different setups.

More microphone options
ARC 4 includes a precision-manufactured MEMS room analysis microphone for the most precise measurements possible. But you can also use generic measurement microphones, and even load a mic calibration file for superior accuracy.

Instantly apply correction
Once you’ve generated your profiles, open your DAW and insert ARC 4 across the master bus. ARC applies a precise correction filter using advanced processing to compensate for your room’s acoustics with a higher level of accuracy than ever before. Now you’re hearing your music free of the impact of room acoustics. You can work confident you’re hearing exactly what was recorded, and your work will translate to other rooms and systems better than ever.

Deep control to fine-tune your correction
Customize your setup for ideal performance no matter your preference. ARC 4 offers deep control over each profile so it always sounds its best:

Target curves
ARC 4 comes with 9 factory tailored target curves suitable for most situations. The default curve offers optimally balanced results with Flat and other specific curves for different needs or setups.

Adjustable correction range
By default, ARC corrects the entire frequency spectrum, but you can define limits to both upper and lower correction ranges separately. This is useful if you want to preserve the unique voicing of your monitors or are just looking to correct a certain frequency range.

Variable resolution and smoothing
Adjust the resolution of the correction filter to use more or fewer frequency bands. Depending on your room’s unique sound, this lets you achieve more surgical correction, or a broader, smoother balance.

2 Phase Modes
Natural and Linear phase modes ensure precise stereo imaging. Natural mode improves the phase response, while linear phase maintains the original inter-channel phase response, which may be preferable in certain rooms and conditions.

Over 20 studio monitor emulations
ARC 4 emulates the frequency and phase response of the most famous studio monitors on the market, working in tandem with the ARC settings for the best possible sound in any listening environment. This is ideal for testing a mix on different reference systems quickly, without ever leaving the sweet spot and ARC’s calibration. You can also use virtual monitoring to intentionally shape your sound to emulate devices like TVs and car audio systems, as well as many popular studio monitors, to quickly listen to your mix on other "virtual" systems to ensure a perfect sound translation.
