This needs, IMHO, a special package. Usual algorithms are not realtime
Real-time arises when there is a time notion, and this needs the use of
chunks and thus a special interface. For instance in audio, the standard is
hard to use, and there are a lot of pitfalls when implementing a host that
respects the different latencies.
