Searching soundfiles per term

Feching sound files from archive.org based on search terms

In order to do that I am making 2 API requests:

• 1 - searching for a given term within mediaType:Audio
  • getting the identifier of the first search occurance id_0

• 2 - requesting details on identifier (id_0)

I use the 2nd (details) API query to look for the containig files.

From this list I get the first ogg (in case ogg files are present)

Downloading soundfile In archive.org files are stored http://www.archive.org/download/ + identifier + filename
