Plotting a waveform with 48kHz samples per second is not that
difficult and it doesn't require HW acceleration or esoteric
hardware.
But *what* do you want to see ? Of one thing you can be sure:
the information contained in 48k samples per second will
overload the visual parts of your brain. If the waveform
is more or less cyclic for some time, you can set a trigger
level and display small fragments - that is what a scope
is doing. In the other case the only thing that makes much
sense is display longer fragments, and then the only info
you get from this the amplitude envelope.
Ciao,
