Say where you were, what you heard, and what else was happening. A short sound clip helps. So does admitting that the microphone was in your pocket. The archive is editorial fiction; draft contributions remain in your browser rather than going to a moderator.
Notes from The Board
This is a fictional discussion archive for people with a noise to identify and a theory to share. Read the recorded threads, try a sound sample, or compose a local draft. Nobody here expects your first explanation to survive the replies.
Our records separate the observation from the explanation. Names, dates, and labels are retained so a later reader can follow the same evidence.
Visit the listening shelf or read the field notes.
Following someone is not ordinarily a navigation method. The archive nevertheless contains a lengthy defence of it.
