Simon also did some brilliant stuff with Datasette based on a 2-hour long mp3 of train announcements that ScotRail released as part of a Freedom of Information reponse. A journalist called Jon Brady found it initially on the ScotRail website and tweeted about it, I chopped it up into individual announcements and crowdsourced the transcription, and Simon built a dashboard to explore them all in Datasette.
