Built with R-Studio and Audacity.
The idea of this project was to aid in Japanese language immersion and reading practice. While one could just watch the videos with Japanese subtitles, I find that just focusing on the text and audio alone is much better for reading and listening practice at the same time. I think of it as kind of like "training wheels" for Japanese literacy and helping to associate symbols with sounds directly. In addition since the html files are viewed in a browser, you can use an extension like Yomichan for easily looking up the meanings of words and kanji. There is no translation included since I find that relying on translation serves as a crutch that might make it easier to understand in the short term, but does get in the way of learning how to read in Japanese.
Automated the process of adding file names to the <audio> tags by using javascript to add the src attribute to them which makes it much easier to produce a new episode. It's all written in markdown with a tiny bit of html thrown in and then Rstudio uses pandoc behind the scenes to generate the html files and javascript fills out the appropriate details both adding a play button and pointing it to each audio file.
Added some notes on how to build your own.
