Zoom H3-VR

The Zoom H3-VR is a unique 3D virtual reality audio recorder with a built-in Ambisonics mic array offering flexible 360° audio capture as well as integrated Ambisonics A-to-B conversion, eliminating the need for external processing. The device goes well beyond VR applications, and is additionally geared towards sound recordists, audio engineers, and content creators in music, audio-for-video, game audio, and AR production.

It features an Ambisonics mic array with four microphone capsules, which can be utilised to record in Ambisonics, stereo binaural, or standard stereo modes, making it well suited for detailed reproduction of studio-based instrument ensembles and solo performances, audiences, sound effects, EFP, and more. The H3-VR supports full-sphere surround sound recording at up to 24-bit / 96 kHz, as well as real-time stereo/binaural monitoring and on-board Ambisonics A-to-B conversion, eliminating the need for additional processing with a computer in post. You can even export your Ambisonics recordings as stereo, binaural, or 5.1 audio files using the free Zoom Ambisonics Player software (downloadable to a Mac or Windows computer).

The unified single-knob gain control, LCD screen, and transport/menu buttons deliver easy and efficient device configuration and operation. Remote access to transport controls, levels, and metadata is possible via the iOS H3-VR Control app and optional BTA-1 Bluetooth adapter. An integrated 6-axis motion sensor is utilised to provide automatic detection of the microphone position, which ensures proper audio-to-video orientation alignment and simple angle leveling. Dual 3.5mm outputs with independent level control enable simultaneous connection to headphones and a camera. Record to an SD card (available separately), or stream audio via USB to a computer or iOS device. The built-in slate function can be used to verbally mark takes and manually align audio and video files.
