Open Projects

AES31-2-R: Review of AES31-2-2006: Audio-file transfer and exchange - Part 2: File Format for Transferring Digital Audio Data Between Systems of Different Type and Manufacture
Project scope: This standard defines a file format for interchanging audio data between compliant equipment. It is primarily intended for audio applications in professional recording, production, post production, and archiving.

A recent draft revision of this document incorporated the recent amendment and EBU loudness metadata consistent with the EBU V2.0 format. This draft had previously been posted to the group with a request for comment. This meeting had no comment on the draft.

Propose to move this draft to PCFC as soon as practicable.

AES31-3-R: Review of AES31-3-2008, AES standard for network and file transfer of audio - Audio-file transfer and exchange - Part 3: Simple project interchange. including maintenance of annex F.
Scope: This standard provides a convention for expressing edit data in text form in a manner that enables simple and accurate computer parsing while retaining human readability. It also describes a method for expressing time-code information in character notation. It supports common professional audio sampling frequencies, video frame rates, and film framing. This document addresses the core need of the AES31 series of standards in providing a simple but extensible system for passing audio material between systems.

No action was requested or required.

AES-21id-R: Review of AES-21id-2011, AES Information Document for audio-file transfer and exchange - Screen-less navigation for high-resolution audio on Blu-ray Disc
Project scope: This information document recommends a method for authoring a BD ROM to enable playback in consumer systems without a video screen, and to provide simple track selection from the remote control.

No action was requested or required.

AES-X212: Head-related transfer function (HRTF) interchange file format
Project scope: to standardize a file format to exchange binaural listening parameters in the form of head related transfer functions (HRTF). The format will be scalable to match the available rendering process. The format will be designed to include source materials from different HRTF databases.

This project has recently been initiated. M. Parmentier was not able to report. A general discussion covered various existing formats and their variants.
