Description

35       AuReadElement transfers audio data from the server to the client appli‐
36       cation, reading num_bytes from the ExportClient specified by element in
37       audio flow flow into data.
38

Note

40       If  the  flow  is  "trivial" (consisting only of an ExportClient and an
41       ImportBucket), the num_samples fields in the ExportClient  and  Import‐
42       Bucket are ignored.
