the audio recordings are now being stored in the audioVideo of the datum, with their description and filename in the same place. (and their attachment). we are using couchdb attachments http://wiki.apache.org/couchdb/HTTP_Document_API#Attachments to store the audio at the moment. although there is a seperate audio service that if you upload to it, will run praat and automatically detect syllables and utterances and split on silence eg: https://speech.lingsync.org/utterances/1372973838837. TODO we should be uploading to the audio service instead because we dont have that much space on the corpus server...
