M480

High density microphone array

The HDAudio-3D project developed a multichannel microphone array of 480 MEMS sensors positioned over an 8 cm radius polyhedron. This complex arrangement yields a total of 120 audio signals, enabling highly precise representation  of the sound field.

Spatial selectivity

Beam directivity over frequency

Microphone signals can be encoded in ambisonics up to  a 7th-order representation for detailed directional analysis and editing of the sound field. The size of the device allows  the estimation of higher-order ambisonic components  above 200 Hz.

At high-frequency, in order to lessen the aliasing-induced spectral coloration, the estimated components are  processed beyond the spatial aliasing frequency using  diffuse field equalization (DFE). Further information can be found in this study, which investigated the perception of aliasing artefacts using DFE.

For each frequency band depicted in the graph, ambisonic components are encoded with  a mean squared error < 5% and the corresponding beam directivities are displayed.

The microphone bundle contains  a powerful set of plugins to edit  and render the M480 signals.

Plugin suite

Plugins will be available in VST3, AU and AAX formats.

Applications

1/3

Immersive field recording

The system supports all multichannel and surround formats, including Dolby Atmos, binaural,  and 3D audio for virtual reality. Its ultra-low noise performance ensures exceptional soundscape rendering, even in the most silent environments. Designed to be both compact and lightweight, it remains highly practical for on-site and studio use, while the high-performance windshield provides effective protection without compromising acoustic transparency.

3D audio broadcast

The M480 delivers low-latency 3D audio for live streaming with Dante/AES67 output. It provides precise 360° acoustic imaging with output signals natively free of phasing issues, ensuring seamless mix integration and excellent down-mix compatibility. A dedicated real-time beamforming and spatial mixing tool enhances sonic immersion in live broadcast conditions.

Spatial Audio Measurements

The HDAudio-3D project has developed a solution for capturing, manipulating and reconstructing three-dimensional sound fields using headphones and dense loudspeaker arrays. In addition, seventh-order Ambisonic Room Impulse Responses can be acquired to evaluate the acoustic properties of a sound space in detail. Namely, the solution enables the analysis of directional acoustic parameters and energy over time.
