“synaptic regeneration algorithm: a fundamentally more advanced method of handling and processing pipe organ data”

Inspired Acoustics announces the immediate availability of the first pipe organ sample library processed with its debuting methodology ‘SPIRAL’, Synaptic Regeneration Algorithm. Scots Pipe Organ Samples II is freely downloadable as a trial version.

SPIRAL is a unique, proprietary methodology featuring custom technology, providing not only musically convincing results, but which allows deep non-destructive parameterization of noise-elimination settings, responsiveness and other elements of the organ sample data in a fully comprehensive, perceptual-based in-house software solution, capable of writing code, parameters and commands prior to compilation in custom-tailored solutions optimized for a given musical instrument.

Development of the SPIRAL methodology started in 2004, before Inspired Acoustics was officially formed and now debuts with the processing of the Scots Church Melbourne pipe organ.

The primary benefits of the SPIRAL methodology – its adaptivity and speed of processing, while retaining the ability to revisit the data at any stage and any time – mean that reduction of the time required in addressing large data sets can be expected to be on several orders of magnitude. The SPIRAL processing framework objectively delivers far better, more musically true results than with former laborious methods, particularly in situations suffering from intrusive stationary or non-stationary environmental noise. Instruments in acoustically constrained environmental conditions, hitherto perhaps not seen as potential candidates for virtualization on account of serious noise issues, can now be more likely regarded as feasible.

“Owing to a multitude of factors, the preparation of pipe organ sounds from raw recordings to virtual instrument data has historically been a highly time-consuming process. For example, in acoustically difficult conditions both the fieldwork and the post processing required much additional time to mitigate environmental noise.” says Inspired Acoustics Head of Australian Operations Stephen Phillips. “The Scots Church in Melbourne is very special in this aspect on account of being surrounded by – if not immersed in – multiple high-level sources of noise”.

With SPIRAL, we can expect to see even more ambitious virtual instruments accessible to the virtual organ community, delivered more quickly, with pristine sound, free of the degradation resulting from relatively antiquated processing or unwelcome residual environmental noise contamination.

“At Inspired Acoustics musicians, scientists and engineers work together to refine the technologies and principles of audio signal processing, with a deliberate emphasis on effectiveness and fidelity to the original sound and speech of organ pipes. Some of the noise-related problems are purely of mathematical nature and we can effectively address them with the proper tools in place. The parallel handling and parametrization of linear and nonlinear processing of tens of thousands of recorded audio samples impose a dimensionality that can be more effectively handled with context-aware methodologies, machine learning and artificial intelligence. This is where SPIRAL has its main merits, in the possibility of providing them.” says CEO Dr. Csaba Huszty. “We are delighted that we could apply these tools first to the Scots organ.” he added.

This powerful new proprietary tool promises substantial enhancement of the playing and listening experience for private, professional, and institutional applications.
