About the Artist

Youngjae Cho (born 1990) is a composer based in Korea and Germany. His work spans solo and chamber music, electroacoustic music, live electronics, and immersive multi-channel audio. Drawing inspiration from everyday sounds and landscapes, he integrates them into compositions performed at festivals across Europe, Asia, and North America.

B-Format to SPS/T-Format Conversion

During his residency, Youngjae Cho explored a spatial audio processing workflow based on converting B-format recordings into SPS (Spatial PCM Sampling) — an alternative approach to Higher-Order Ambisonics that encodes spatial information as spatially dependent filter channels. This enables traditional audio processing techniques (denoising, EQ) to be applied to immersive recordings before re-encoding back to B-format.

The workflow developed at ICST:

  1. Convert the field recording to 3rd-order ambiX B-format
  2. Decode to T-format (SPS) using the SPARTA AmbiDEC plugin
  3. Apply traditional processing to the PCM audio channels
  4. Re-encode from T-format back to 3rd-order ambiX B-format
  5. Upscale to 7th-order ambiX for playback
