Development of an Ambisonic Guitar System
What is GASP?
Guitars with Ambisonic Spatial Performance
- An innovative audio project, fusing the musical with the technical, combining individual string timbralisation with Ambisonic immersive sound
 - An artistic musical project, providing alternative experimental surround sound production ideas for the guitarist and music producer
 
GASP System Hardware

Previous Work
- Post-Production Based
 - Experimental Production Techniques
 - Now implemented in UG and PG Teaching
 
The Live System



Guitars And Pickups

Ableton Live
- Clip Based Control
 - CC for Spatialisers
 - PC for Helix patches
 






Pedalboard
- Behringer FCB1010
 - Triggering clips in Ableton
 - Expression Pedal controlling Tempo
 






GuitArpeggiator
- MIDI Note sequence in Ableton
 - MIDI Note filters
 - TrackGate per String
 












Timbral Morphing
- Sending guitar signal to quad panner
 - Each “speaker feed” goes to a separate processing path
 - Enables timbral morphing effects
 


Frequency Band Splitting
- Taking standard (mono) guitar output
 - Splitting to 6 frequency bands
 - Sending each band to an individual processing path
 



Future Work
- We are currently exploring funding for a GASP PhD studentship
 - Rationalisation of the system
 - True 3D representation (currently 2D)
 - Enhanced Binaural representation
 
Funded By

 - ICE (Intellectual Capital Exploitation) fund
 - RLTF (Research For Learning and Teaching Fund)
 - URSS (Undergraduate Research Scholarship Scheme) funding
 - Vice Chancellor’s Ideas Forum Award
 - College of Arts Research fund: Research assistant
