A favorite bit of audio history is how Bing Crosby made use of technology captured from Nazi Germany. Radiolab has the story as part of its Mixtape podcast series.
Additional details are available from Vox:

The first part is fascinating, about the “rescued” cassettes in China.
Yes! I really enjoyed the Mixtape series on Radiolab. Fun stuff!
