There is an import feature on Anki that allows the user to import their CSV files saved in UTF-8 encoding, which the program later converts to .akpg files.
I would like to add sounds (ideally .mp3 audio) to each flashcard of my deck, which doesn't seem possible using those CSV files.
Is there a solution to this issue that does not involve programmatically generating the .apkg? And if not, how can I write a program to do so (preferably in Java)?
