How does Nyquist's theory apply to digital recording of opera music?
Well, you can always run ADC at 384KHz with 8x oversampling, followed by digital anti-aliasing filter and downsampling to 48KHz for transmission/storage. Same thing on the playback side - digitally upsample to 384KHz using proper sinc interpolation before sending it to the DAC. This way analog filters are a lot less critical, noise and jitter are much reduced, basically you get a couple of extra bits of resolution.
