Hello, I'm using GNSDK for multiple file recognition. I use this function gnsdk_musicidfile_query_do_libraryid with such keys 


Callback for fetching fingerprint is called simultaneously, but sending fingerprints and receiving result not. Is there any way to do recognition simultaneously?


Supposedly when you do async, fingerprints should be sent one after another, and (available) results should be returned as soon as it's available.
Can you provide a snapshot of the callback messages so that we can better understand your question?
Perhaps you can try using synchronous flag and see if that is what you need.
