Masterful Sound Engineering

Legacy and Innovation

Born from Vienna's rich heritage in sound engineering, the OC818 is Austrian Audio's flagship microphone, integrating traditional craftsmanship with contemporary acoustic design. This microphone is the culmination of decades of experience in the audio industry, created to fulfil the needs of both modern recording environments and the demand for reliable, high-quality sound.

Handcrafted Ceramic Capsule

The OC818 features the CKR12 ceramic capsule, a component crafted with precision and care. Reflecting the brand's ethos of quality and consistency, this capsule ensures the microphone delivers a warm, clear sound, making it a reliable tool for producers and engineers.

Customisable Audio Capture

Designed to adapt to any recording situation, the OC818 offers flexibility with its multiple polar patterns. This versatility allows for a wide range of recording techniques, from capturing the nuanced dynamics of a solo vocalist to the powerful presence of an orchestra.

Seamless Remote Control

The integration of the PolarPilot app provides a modern twist to microphone technology, allowing for remote adjustments of patterns, filters, and pads. This fusion of analogue warmth and digital convenience caters to the evolving landscape of music production.

Boundary-Pushing Software

Complementing the microphone’s hardware, Austrian Audio’s PolarDesigner and StereoCreator plugins extend the OC818's capabilities into the digital realm, offering innovative post-processing options that redefine the boundaries of microphone technology.

Analogue Integrity

Despite its advanced digital control features, the OC818 maintains a completely analogue audio signal path. This design philosophy ensures the microphone’s output remains untouched by digital artefacts, preserving the integrity of the captured sound.
