def save(self, uri, uncompressed=False):
'''
Saves this recording to a URI as a compressed .tar.gz file.
Returns the URI of what was saved, or None if there was a problem.
Optional argument 'uncompressed' may be used to force the save
to occur as a directory full of uncompressed files, but this only
works for URIs that point to the local filesystem.
For example:
# Save to a local directory, use automatic filename
rec.save('/home/username/recordings/')
# Save it to a local file, with a specific name
rec.save('/home/username/recordings/my_recording.tar.gz')
# Same, but with an explicit file:// prefix
rec.save('file:///home/username/recordings/my_recording.tar.gz')
# Save it to the nems_db running on potoroo, use automatic filename
rec.save('http://potoroo/recordings/')
# Save it to the nems_db running on potoroo, specific filename
rec.save('http://potoroo/recordings/my_recording.tar.gz')
# Save it to AWS (TODO, Not Implemented, Needs credentials)
rec.save('s3://nems.amazonaws.com/somebucket/')
