Mission statement: AES high-resolution audio technical committee

The core mission of the committee is the quest for a comprehensive understanding of high-resolution, multi-channel audio technology in all its aspects.

The committee seeks to influence the advance of enabling technologies and audio engineering evolution by promoting the highest standards of technical performance and sound reproduction commensurate with application and channel capacity.

High-resolution audio embraces a wide parameter set that impinges on the primary elements of bandwidth, dynamic range and spatial acuity. New technologies are enabling system resolution to be extended to the extremes of engineering capabilities and ever-greater performance is expected. It is critical that the absolute performance boundaries be studied to enable a holistic understanding of both technology and supporting perceptual auditory theories.

The committee will embrace a wide range of activities that are seminal to its prime purpose. It aims to influence audio applications where a high standard of audio performance is expected and to promote best practice commensurate with the limitations of a given medium.


Areas of Concentration

  • Theoretical issues
  • Bandwidth, sampling rate, dynamic resolution and spatial representation.
  • High-resolution signal processing, 1 to n bit paradigms.
  • High-resolution system technology
  • Spatial audio, virtual and acoustic spaces, virtual image manipulation.
  • ADC and DAC system design and performance.
  • Analogue and digital systems and circuitry.
  • Network delivery of high-resolution audio.
  • DVD: present and future audio coding formats.
  • DVD: present and future physical structures.
  • Perception
  • Perceptual modelling.
  • Perceptual coding.
  • Objective evaluation and subjective performance of high-resolution audio
  • Objective measurement techniques and resolution issues.
  • Subjective procedures and evaluation psychology.
  • Education and networking
  • To inform and educate the membership about the important issues of high-resolution audio technology and applications.
  • To network with other Technical Committees in order to involve them in the study of high-resolution audio.
