Loop upload & transcode multiple files

I have a set of audio needs to loop upload & pre-transcode to seven kn. The information I need to return is returned in the order in which they were uploaded.
I wonder if the seven-ox upload return result is asynchronous? Who successfully returned the message first?

Like seven cows have synchronous also have asynchronous upload, certainly who first successfully return who, and even if synchronization due to network problems no one can guarantee to start first completed, but you can use custom parameters to add the order number, the callback time to judge not on the line.
