| *One line summary* | The extraction of technical metadata and embedded 'descriptive' metadata from audio files of multiple, esoteric and proprietary formats. \\ |
| *Detailed description* | Audio files intended for long-term preservation may be created outside of the control of standardized archival workflows. \\
To archive such files, lossless normalization to a standardized file type is ideal, alongside the accurate description of the original file's technical metadata for inclusion in the recording's catalogue entry.  Descriptive metadata (in ID3v1/v2 tags or BEXT chunks) may also contain information useful for the enhancement of catalogue data.  \\
Normalization to a single lossless audio format or format or different type risks the loss of such information.  The extraction of this metadata is therefore vital prior to normalization.       \\
While Jhove performs a similar function for WAVE and MP3 files, support for multiple file formats is limited.  \\

| *Possible approaches* | Software tools for describing the technical makeup of digital audio files and their embedded metadata exist, but are limited in functionality, format support and structuring around manual or GUI-based interfaces; requiring the use of multiple tools or parts of tools to achieve a simple, single goal.  Manually exporting useful data from such tools is perfectly viable for single files of limited types, but proves inefficient when faced with large and technically-varied collections.  Ideally, this would be solved by a single command line-driven tool for exporting metadata in a directly-usable or transformable format (xml, for instance), which could be incorporated into batch scripts to automate large-scale metadata extraction. \\ |
