{'label': 'sound_1_url', 'ref': 'sounds[0].file_url'},
- for a comma-separated list of all the sound file urls for each observation:
{'label': 'sound_urls', 'ref': 'sounds', 'function': 'filter_select', 'params': {'select_ref': 'file_url', 'separator': ', '}},
- for a count of the number of sounds per observation:
{'label': 'sounds_count', 'ref':'sounds', 'function': 'count'},
