The 31st International Audio Engineering Society Conference, entitled New Directions in High Resolution Audio, will be held at Queen Mary, University of London, from June 25th-27th, 2007. 

This Conference is concerned with the promotion and delivery of high resolution audio, by maintaining quality throughout the recording and playback chain with current and future technologies. It reflects the tremendous recent growth of high resolution audio techniques and products intended for use throughout the audio recording and playback chain. However, issues remain on how to avoid bottlenecks where quality is compromised, and how to maintain and encourage high resolution audio in an everchanging marketplace. These concerns are of interest to the audio engineering, recording and production industries, as well as to education and academia. 

We aim to provide a place for the exchange of news, issues and results, by bringing together researchers, developers, educators, students and professional users, working in fields that contribute to high resolution audio, to present original theoretical or practical work. It also serves as a discussion forum, provides introductory and in-depth information in specific domains, and showcases current products.

The 31st AES Conference solicits contributions to the field of high resolution audio, including, but not limited to, the following domains and topics:

High resolution recording issues
* Bandwidth, sampling rate, dynamic resolution and spatial representation. 
* Analog and digital recording equipment

Processing, manipulation and preparation of high resolution signals
* High quality analog design 
* A/D and D/A conversion 
* Format and sample rate interconversions
* High-resolution signal processing, 1 to n bit paradigms
* Spatial audio, virtual and acoustic spaces, virtual image manipulation

Storage of high resolution audio
* Current and future storage technology for high-density audio data
* Overview of high resolution consumer formats 
* Copy protection
* Access speed, data reliability, bit packing and compression
* Professional archival formats and future-proofing

Electronic delivery of high resolution audio
* Network (wired and wireless) systems/delivery of high quality audio content 
* Current and future formats for streaming and file delivery of high resolution audio
* Bandwidth
* Digital radio and broadcast applications including multichannel audio

Maintaining quality at playback
* Evolving technology for multiformat players
* PC-based playback: configuration and interfacing 
* Converter technologies
* Jitter/interface/power supplies and other related forms of noise
* Digital amplification e.g., Class-D amplifiers 

Perception 
* Perceptual modeling. 
* Objective evaluation and subjective performance of high-resolution audio 
* Objective measurement and resolution issues
* Subjective procedures and evaluation psychology
