This American Life's Audio Hackathon was last weekend. It was a good time exploring different ways to enhance podcast creation, discovery, and consumption.
My team worked on a web app that synchronizes social and multimedia content – photos, ads, tweets, videos, maps, links, etc. – with an audio file. The basic idea was to make it easier for listeners to engage with external content referenced within a podcast episode. For example, if the host is talking about a specific celebrity tweet, this app could display said tweet at the specific time in the podcast when it's being referenced. It'd also be awesome for a show like Serial, where the producers would be able to annotate the show with actual documents and additional details about the case – synchronized show notes.
From the docs:
Memento.js binds data to regions of audio or video and allows you to quickly recall the results at any point during playback or scrubbing. Calling the
.data()method on a memento object will retrieve the data corresponding to that point in time. Calling the
.data()method repeatedly at different points in time will retrieve different data.
