I would actually think that callback will be more efficient as long as you
can specify a number of packets for each callback and max number of CSRCs.
 This should be similar to ScriptProcessorNode in Web audio and will allow
to control the latency acceptable to the application, will not require any
processing when it is not used, will provide detailed info about audio
levels to implement any required post processing, and will allow to
optimize allocation of needed data structures.
