What about a delaying the output so that it becomes causal (I mean it would have a huge latency).
Latency is not an issue in non-realtime.

That would be one solution, however the plug-in would be forced to allocate a huge amount of memory to hold the entire selection (which might be huge).

Also, it would be very difficult for the host to estimate the required time to process the sound (for displaying a progress bar or something), since the plug-in would spend almost zero time copying the incoming samples to its internal buffer, and then do all the work at the end, when it has received all the samples.

In some cases, I don't know if you know Mike Norris' Sample Hose plug-in for SoundEffects/SoundMaker (we're talking five years ago, here), such a plug-in would need to store minutes worth of samples into its internal buffer, when it could simply ask the host to skip its read head to a different position along the timeline...
Same thing goes if you're doing a Reverse on a 5-min waveform.

Alberto.
