Banish loudspeaker distortion and specular reflections from your listening space

Diffusion At Source

The acoustics of your listening space need no longer 'colour' the sound you hear.

Effectively preventing the conflicting specular (mirror-like) reflections made by the typical listening space, 'Diffusion At Source' means the playback sound more accurately recreates the recording.

By ensuring you hear the recorded cues unchanged, Diffusion At Source enables your audiology to construct a more 'apparently real' perception.

The original recorded spatial cues do not become lost among listening space reflections. More importantly, they're also not distorted by the swirling off-axis intensity vectors typical of conventional loudspeakers. The listeners' audiology is then free to use the resulting accurate spatial cues to create their perception of 'being there' at the recording.

NEWS - Dr Toby Gifford presented our science at the Acoustic Engineering Society's Burlingame Conference. The paper (featuring his mathematics) explains not only how 'Diffusion at Source' is achieved - but more importantly, what it does that is so different to what conventional speakers do. His presentation "went off like a frog in a sock" (a good thing) according to Dr Toby (He's Australian!)

Value Proposition

Market Verticals/Applicability

Making sound clearer, more engaging and perceptibly louder is the 'triple-whammy' that all engaged in sound reproduction seek.

Customers too, invariably vote with their purchasing decisions as to which products are closer to the ‘reality’ they seek.

Everything that communicates sound is thus effected.

Home Hi-Fi may be the obvious application of the A3D technology, but TV’s too (and increasingly, Smartphones) are the devices many people now choose to experience ‘realism’ - wherever they are.

Smartphones are also often used in Teleconferences and Video Conferences, and consequently they need better audio. Clear intelligible audio that allows hands-free full-duplex calls would help – A3D’s technology delivers that.

Motor vehicles too, are now considered as ‘entertainment venues'. Audio is also preferred to provide navigational information to the driver. And let's not forget those all-important phone calls! Producing clear sound in the highly reflective space that is the interior of a car isn’t easy. Conventional solutions try to overpower reflections and other speaker-related issues through the use of a large number of loudspeakers – in the process potentially masking important external auditory cues, and possibly inducing tiredness, as well as adding weight, complexity and cost. With A3D speakers, all occupants can enjoy concert-hall quality sound from just three or so loudspeakers - with a clear and immersive sound, and a sound stage where it should be - in front of the listener.

Public Address – particularly in large spaces – is very susceptible to the impact of reflections. Treating those reflections at source makes for message intelligibility independent of the architectural environment. It makes the sound more engaging too. PA also needs a wide 'sweet spot' if it is to provide good sound to everyone in the audience.

Clearer sound is what the public want - and expect.
