Yes. I believe Audacity only loads the graphical waveform view into RAM

and the rest is streamed from disk. Dominic

Mazonni (audacity's lead developer) explained the exact algorithm once

so I assume the algorithm is a bit complicated.
I have opened and worked on files over two hours long in Audacity.
