All sounds originate from a classic recording of a Balinese gamelan orchestra. Granular synthesis is used to pick out clouds and grains of source sound from the recording, which are then molded into various forms by signal processing. Vocoded noise, resonators and filters are the main digital effects used to shape the sounds.

Refraction Redux

The glitch-type aesthetic of this track was established using granular synthesis. Larger grain sizes are used to achieve a glitch-like texture, instead of the cloud-like textures normally resulting from granular synthesis.

The primary audio source material used for this track is the original studio recording of "Troy" by Sinead O'Connor, from her debut album "The Lion and the Cobra". Also utilized as source material is a solo recording of a Sufi flute.  

 The rich presence of the sounds here and the varying character of the track's changes from section to section, both stem from the originality, strength, harmonic power and resonance contained within Sinead's recording of "Troy". 

The title, "Nimbus of Yelena", refers to its source. A nimbus is like a halo or aura, and something akin to Sinead's sonic aura emerges throughout the misty amalgams of audio grains which blend into the glitchy bricolage featured here. 'Yelena" is another name for 'Helen', a.k.a. Helen of Troy.

Besides the drum loop, all sounds in this track originate from Sinead's "Troy" and the Sufi flute recording.



Nimbus Of Yelena

Here's a little medley mix of a few music examples I did for EarSketch, utilizing the power and elegance of recursion and self-similarity to computationally remix some loops from Young Guru and Richard Devine.
