all the "slower" vs "faster" is non-sense.
signals are handled in a _synchronous_ way (they have to process 44100
samples per second; synchronized with the soundcard); they do this
continuosly (once you have started the audio-engine they will process
44100 samples/sec until the end of the world, or the audio engine gets
