The IK Multimedia ARC 4 is a room correction software solution tailored for audio professionals, transforming the mixing process with unparalleled accuracy. This innovative system facilitates a workflow that ensures your music resonates with fidelity across all listening environments.

Immaculate Audio Monitoring

Combining a precision measurement microphone with advanced analysis software and a correction plug-in, ARC System 4 guarantees accurate monitoring regardless of the room. This integration allows for swift and assured music production, maintaining the integrity of the original sound.

Reliable Sound Perception

The acoustics of your environment can significantly alter your sound perception. ARC rapidly calculates your room's acoustic characteristics, crafting a corrective filter that integrates with your DAW, affirming the authenticity of your auditory experience.

Revolutionary Listening Experience

ARC 4 debuts a novel analysis and correction algorithm, surpassing the capabilities of traditional digital room correction systems. It utilises IK's VRM™ technology to produce a 3D acoustic mapping, pinpointing problematic areas without compromising sound quality.

Opt for an extensive 21-point measurement or a more expedient 7-point method. Both are designed to deliver superior sound for stable installations or dynamic setups.

Instant Correction Application

After crafting your profiles, apply ARC 4 directly across your DAW's master bus. This introduces a refined correction filter that neutralises room acoustic effects, ensuring the integrity of the recorded sound across various spaces.

In-depth Acoustic Customisation

With ARC 4, fine-tune your room's acoustic settings to achieve ideal performance in any setting:

  • Tailorable correction range
  • Variable resolution and smoothing
  • Choice of natural or linear phase modes

Efficient Mix Monitoring

ARC System 4 reproduces renowned studio monitors' frequency and phase response, allowing you to test your mix against multiple reference systems without leaving your desk.

Workflow Optimisation with Precision Metering

Peak, RMS, Loudness, and dynamic range metering are among the advanced tools provided by ARC, along with a real-time spectrum analyzer to understand your music's interaction with the room's acoustics before correction.
