Please excuse x-posting…

Announcing the first public release of the D4 spatialization library for

Max featuring:

– Innovative Layer Based Amplitude Panning algorithm that can handle

just about any loudspeaker arrangement with particular focus on High

Density Loudspeaker Arrays (HDLAs)

– Innovative implementation of high precision audio source radius,

Spatial Mask, and Motion Blur

– Unique visual spatialization editing tools for hobbyists and

professionals alike, including spatial source painting

– Ability to spatialize a broad array of multidimensional data by

leveraging the Jitter library

– Multilayered system with independent layers and focus on

perimeter-based 3D immersion

– 3D visualization of spatial audio and hooks for immersive scenarios,

including Virtual Reality (VR) and Augmented Reality (AR)

– A comprehensive collection of time-based editing tools

– A Mostly Open Source Software (MOSS) approach empowering users to

tinker and improve the system

– Lean and optimized implementation leveraging maximum amount of

built-in MaxMSP objects, including dynamic creation and parallel


– A drop-in replacement for the existing spatialization options (e.g.

using azimuth and elevation)

– Ideal for researchers, production engineers, and artists alike

D^4 has been utilized in the Virginia Tech ICAT Cube with 128 channels

of audio at 48KHz 24-bit using Dante interface with single audio buffer

size of 256 bytes (or 5.33ms) with 21 simultaneous audio streams, 5 of

which were in constant motion, for a total of 1,018 software audio

streams being mixed down to 128 physical channels. No audio dropouts

were observed in the said scenario.

D^4 will be officially unveiled on July 4th, with the first workshop

being held on July 6th in Canberra, Australia, as part of the ICAD 2016

conference. Later this fall, D^4 will be also presented as part of the

ICMC 2016 workshop in Utrecht, Netherlands.

D^4 is currently available at an introductory price for both students

and professionals.
