At a Copal 0 shutter speed of 1/500 of a second (although in practice it won't be that fast), you're talking about the shutter opening and closing in 0.48 of a frame. On a DSLR, you'd need a close-up lens, but the more recent iPhones, and probably some others, will record at 240fps.
For practical purposes, I think that an audio recording, with the waveform displayed on a full computer screen, works fine.
