Martin Audio loudspeakers in combination with Astro Spatial Audio software and processing unite your audience in an unrivalled immersive 3D sound field.
Utilising patented acoustic technology the result is scalable and easy to operate fully object-based immersive audio delivering new creative options for live acts and theatres worldwide, as well as installations in a variety of venues.
Since 2016, Astro Spatial Audio has been deployed on Broadway, the West End, in opera houses and auditoriums as well as nightclubs and art installations.
Using adapted Wave Field Synthesis algorithms, Astro Spatial Audio’s SARA II audio rendering engine is an immersive 3D audio tool for live and entertainment venues.
Martin Audio now offers Astro Spatial Audio as parted of an integrated offering with its loudspeakers.
Traditional Channel based surround audio has drawbacks in that playback occurs only on the same speaker arrangement as during production; it’s not possible to provide a fuller, richer sound if you expand your system, and offers little adjustment by end user.
The SARA II Premium Rendering Engine utilises object based audio which provides full control over position, level, acoustic characteristics and distance to enable a more flexible loudspeaker system to provide sound anywhere within the room in the most realistic and natural way.
The SARA II turns audio inputs (pre-recorded material, audio console, mics) into Audio Objects by adding metadata:
Martin Audio Loudspeakers are mapped in the software and each audio source / object can be placed or moved in real time - or via a timecode, cue based or with a tracking system - through the 3D listening space.
The listener hears the objects, not loudspeakers, with interactions between loudspeakers and Doppler effects eliminated via algorithms.
Create a truly dynamic experience for the audience with sound effects and mixes that can move in real time throughout a venue. The control of light and video systems can also be coupled with the sound system.
A unique dynamic sonic simulation creates a large variety of natural sounding room acoustics that can electronically shape a venue to meet the intended acoustic properties of an event. Transform a lifeless performance hall to have the dramatic acoustic properties of an operatic auditorium or cathedral.
Traditional sound reinforcement with left/right audio will mean for large proportions of the audience they do not enjoy the benefit of true stereo image.
With several sources distributed across the front of stage, the SARA II engine can adjust the output from each source to provide more of the audience with stereo image. The more sources, the more of the audience is covered with stereo image.
As a result the ‘sweet spot’ becomes a ‘sweet area’ and walking the room the image is consistent and stable.
Track performers on stage and position sound accordingly in the venue so every member of the audience align their visual and audio experience, for a truer, more impactful performance.
The SARA II engine can integrate with both Stagetracker II from TTA as well as BlackTrax.
