At the heart of Vienna is a deep tradition of love for music.

At the heart of our revolutionary OC818 and OC18 is an equally passionate commitment to sound and engineering excellence. Each of these Large Diaphragm Condenser (LDC) microphones has a handcrafted Austrian Audio CKR12 ceramic capsule as its heart. There are very few people that can design, let alone construct, a classic edge-terminated capsule. There is also the question of building them by hand in Europe. 

We bring passion to everything that we do, and nobody brings more passion to making our CKR12 ceramic capsule by hand then our very own Monika. See, Monika has been building high-end transducers since the mid-1990s. Her hands have carefully constructed some of the most respected audio tools in the world. When she wasn’t making classics, she was training a new generation on the art and craft of proper transducer construction. That tradition and heritage continues as Monika has made every CKR12 to date along with most of our microphones and is now training the next generation of historic transducer and microphone builders at Austrian Audio.

The OC818 features dual audio outputs that allows the recordist, engineer, musician and forward-thinking artist to record the rear facing capsule independently of the forward-facing capsule. A Mini XLR to XLR adaptor for the rear output is included. 

If both capsules are recorded to a stereo or dual-mono track, our free and Open Source PolarDesigner plug-in (Mac/Win: VST, AU & AAX) will allow for unprecedented control and tailoring of polar patterns between 1 and 5 bands with selectable crossover points during the mix process.

  • Design the polar pattern of your dreams
  • Craft different polar pattern
  • Responses across 1-5 crossover bands
  • Store, recall, and share presets
  • Powerful Terminator AI for eliminating or rescuing selected frequencies and instruments
  • Equalization control for imprinting the tonality of freefield or diffuse-field idealized responses
  • Solo/mute each band
  • Full automation of course
  • Phase linear
  • Optimized for use with the OC818 in Dual Output mode but works with any dual output source
  • Excellent for busy sessions (we’re looking at you, Nashville!) - tune instrument pickup during the mix stage!

The OC818 is also the first multi-patterned microphone to feature the world’s first wireless pattern and switching control via an optional transmitter/receiver (OCR8) that can be fitted to the rear of the microphone. This unique feature allows for a previously unheard of 255 discrete polar patterns between figure-of-eight, through all of the cardioid versions and into omnidirectional. The free control software, PolarPilot, will be available for iOS and Android. This all occurs in the analogue domain and there is no processing or conversion of the mic’s signal to digital.

  • Free PolarPilot app (Android and iOS) allows wireless control over your analogue: patterns, high-pass and pad in real-time via BlueTooth
  • Save, recall, and share favourite settings
  • Discover and create 255 discrete polar patterns. 
  • One setting may be stored in OC818 for use without PolarPilot app
  • Your OC818 is always pure analogue.It is only the analogue bias voltages that are being governed remotely. Switching also is always analogue. No digital in either the audio or bias paths.
  • 60 second OC818 clipping monitor/logger
  • Wireless control from the comfort of your chair!

*Optional OCR8 Required.

A quick run-through of the features you can unlock when adding the optional OCR8 wireless transmitter/receiver (available at your Austrian Audio dealer) to your OC818 Viennese microphone with the handmade CKR12 capsule. Once paired with your Android or iOS device, you can control your microphone from the comfort of your control room (within the parameters of the BlueTooth specification, of course). No need to get up and run back and forth to/from the control room or to have your assistant stop making coffee. Just leave the connection active and you can change the polar patterns at any time (High-Pass Filters, the 2 types of Pads [capsule bias pad and mic output pad] too!) There is even an ultra-handy 60 second clipping monitor/logger window that will show you any internal clipping in the microphone. Use the -10dB pad if this occurs too frequently or tell the boom op to move a bit farther away from the jet engines you are recording. The mic withstands 148dB before clipping without any pads engaged, so you should be fine in most cases. Note: our OCR8 wireless transmitter/receivers would allow for one control device (iOS/Android) to connect to multiple OCR8s. It is currently impossible as no phone/tablet allows for controlling two devices (stereo, as an example) via one software interface/device. However, the OCR8 is ready if this changes in the future. Keep in mind that the signal from your handmade CKR12 capsule is NEVER CONVERTED TO DIGITAL. The OCR8 simply enables wireless control over the capsule bias voltages. #2 of 3 introductory videos. Uploaded first as it is the shortest of the three. === Ein kurzer Überblick über die zusätzlichen Funktionen, die der optionale OCR8 Bluetooth-Sender/Empfänger (erhältlich beim Austrian Audio-Händler) freischaltet, wenn er in Kombination mit dem OC818 Großmembran-Kondensator-Mikrofon und der PolarPilot-App verwendet wird. So entfaltet die handgemachte CKR12-Mikrofonkapsel ihr volles Potential! Sobald der OCR8-Dongle mit einem Android- oder iOS-Gerät gekoppelt ist, kann das Mikrofon über die App komfortabel vom Abhörraum aus gesteuert werden (im Rahmen der üblichen Bluetooth-Reichweite, natürlich). Damit gehört der ständige Weg in den Aufnahmeraum, nur zum Ändern von Mikrofon-Parametern, der Vergangenheit an – und die Assistenten können sich voll und ganz auf das Kaffeekochen konzentrieren. Einfach die Bluetooth-Verbindung aktivieren, und Änderungen an der Richtcharakteristik sind jederzeit möglich (genauso wie das Einstellen von High-Pass-Filtern und zwei Arten von Pads). Zusätzlich bietet PolarPilot einen 60-sekündigen Clipping-Monitor/Log, der internes Clipping im Mikrofon anzeigt. Wenn das zu oft passiert, hilft das -10dB-Pad – oder ein bisschen mehr Abstand zur Tonquelle, wenn man unbedingt ein Jet-Triebwerk aufnehmen will. Allen üblichen Tonquellen mit bis zu 148dB Schalldruckpegel hält das OC818 sowieso ohne Clipping stand – und das auch ohne Hilfe der eingebauten Pads. Bitte beachten: Unser OCR8 Bluetooth-Sender/Empfänger ermöglicht es, dass ein Android- oder iOS-Gerät mit mehreren OCR8 Sendern/Empfängern verbunden wird (zum Beispiel zum Kontrollieren eines OC818 Stereo-Paars). Leider gibt es aktuell kein Smartphone oder Tablet, das eine Bluetooth-Verbindung mit zwei Geräten zulässt. Falls sich das in Zukunft ändert, ist der OCR8 jetzt schon bereit dafür. Und nicht vergessen: Das Signal der handgemachten CKR12-Kapsel wird im Mikrofon niemals digitalisiert. Der OCR8 Bluetooth-Sender/Empfänger wirkt lediglich auf die interne Vorspannung der Kapsel ein, und ermöglicht somit die kabellose Einstellung von Richtcharakteristik, High-Pass-Filter und Pad.

Austrian Audio's Microphones: In Depth on the making of the mics. #1 of 3
Go in depth on the OC818 and OC18 microphones! This is the longest of our introductory series and focuses on what makes these Austrian microphones special. The prior 2 videos focused upon PolarPilot and the OCR8 (world's first wireless polar pattern controller for an analog mic) and our Free and Open Source plug-in: PolarDesigner. But of what true & lasting value are fantastic & forward-thinking features without a world-class sound from which to start? Beginning with Monika's handmade capsules and on to the 335+ years of engineering experience, learn what is going on inside the acoustics and electronics of these future-classic large diaphragm condenser microphones. Our experienced heritage design team and engineers poured every bit of knowledge, heart and soul into making the finest microphones that can be currently manufactured on Austrian soil. This video can be considered as an owner's manual of sorts. Grab a coffee or favorite brew and spend a few quality minutes getting acquainted with all that these mics can do. That rhymes. Yeah, we're an audio company and music & passion are in all that we create. We hope the same is true for you and we will help by providing the tools. Visit our website for more information: Watch
