A Podcast feed is a document that lists the episodes in a given podcast. Each entry in the feed has a title, a date, and an ddress for the audio file.
Replay makes a few tweaks to a podcast feed, to change the dates so that the first few episodes can be heard instantly, with subsequent episodes delivered in the original cadence.
That means if you rewind a daily podcast, you’ll get an archived episode every day, starting from episode one. If you rewind a wekly podcast, you’ll get each episode in order, week by week.
We use today’s date as the new starting point for episdoe one, and actually fast-forward a couple of weeks from that point, so you’ll get the first two episodes (or more if the show is more frequent). That way you can evaluate the podcast over a few episodes before deciding to stick with it or not.
Who made this and why
I built Replay to keep my coding muscles toned, and because it’s the sort of obscure-but-useful tool I like to see exist in the world.
Points of order
Rewind does not alter the original feed (there’s no way for it to do that). It doesn’t re-host any media, so if you’re a podcaster, your stats will show normal listening activity.
The tool doesn’t rewrite the feed completely; it just changes a few things. An
<itunes:block>tag is added so that the feed can’t be indexed by Apple Podcasts, and email addresses are removed from the
<managingEditor>tags where possible.
There are no user accounts and no statistics being gathered about subscribers or feed owners. There isn’t much of a database powering it, either. I list the feeds that have been rewound and the date the feed was requested, but no user activity is logged at all.
If you have any questions or concerns (or if, for some reason you want to block a feed from being rewound), you can email email@example.com.
