I am hoping to compile a list of existing standards or recommended approaches for describing acoustic files, including any notable strengths or weaknesses with the systems.
My team has access to large inventories of acoustic soundscape recordings (hopefully I am using that term correctly; unprocessed multi-hour recordings) that have been described in different ways depending on when, how and by whom they were captured. We are hoping to standardize the metadata describing them to make it easier to locate and use files of interest. If appropriate, we can establish our own recommended system, but 1) don't want to further complicate the space if suitable standards already exist, and 2) would like to ensure anything we did make addresses known issues.
Does anyone know of standards or approaches worth considering? I suspect there may be three 'levels' or types of systems out there:
- How to describe soundscapes or the original full-length recording
- How to describe recording clips extracted from x-y time points in a full length recording
- How to describe an annotation for a known or unknown noise in a clip
We are most immediately interested in soundscape examples, but having a convenient list of each might be useful for the community.
