Wearable audio recorder and retrieval software applications for long term audio and related data recording, visualization, filtering, search, and proof of provenance, providing a record-all and find-later methodology capable of finding audio in multi-year audio data streams. System default state is to record permanently, allowing the user to decide when not to record instead of when to record. User interfaces enable users to retrieve desired recorded audio data by querying other types of recorded data which are related to the desired recorded audio data by way of time and spatial domains.
