Martin Audio Sound Adventures

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.

Object Based Audio

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.

More than just 360˚
its Fully Immersive 3D

The SARA II turns audio inputs (pre-recorded material, audio console, mics) into Audio Objects by adding metadata:

  • Level
  • Spatial position
  • Acoustic characteristics
  • Velocity
  • Distance
  • Point source or Plane wave (=point source at infinity)

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.

Benefits for the Engineer

  • Less critical speaker layout
  • Quick setup times
  • Exchangeable between venues
  • No audible artefacts
  • No change in workflow
  • Integration with tracking
  • Third party support / OSC

Benefits for the Audience:

  • Immersive Experiences
  • 2D, 3D surround
  • Matches visual and audio experience as one
  • Full stereo image for more of the audience
  • Improved localisation on stage
Workflow Summary

System Overview

Moving Sound for Added Dimension

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.

Perfect for dynamic theatre events or creating sonic experiences in theme parks and AV art installations.

Dynamic Variable Room Acoustics

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.

Perfect for speech reproduction or concert acoustics.

Unite Your Audience in Stereo
Traditional Sound Reinforcement

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.

Sound Reinforcement with SARA II

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.

Stagetracker II
Track Performers & Position Sound Accordingly

Track up to 100 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.

Stagetracker II integrates seamlessly with the Astro immersive audio system over Open Sound Control. Based on state-of-the-art RF technology, Stagetracker II is the world’s most accurate RF performer tracking solution in 3D. Tags can be invisibly hidden inside clothing or costumes and Stagetracker II sends SARA information about the position of all the tagged performers and in real time SARA can position them in a 3D space.
