For people who are just starting to learn a foreign language, the best choice for listening is audiobooks that are simplified or abridged. To simplify

I know about several series of abridged audiobooks: "Oxford Bookworms", "Penguin Readers", "Cambridge Readers", "Macmillan Readers".
Most of them can be found via torrents.

listen and get accustomed to voices of ordinary people, not professional narrators). It is easy to get lost in long list of book in this library,
so I recommend to start with these links:

taking long time to convert) solution is to use free audio editor Audacity – see
