@JordiGH A perfect recreation if you only take sample rate into account! Bitrate however is a far more interesting debate. Changing the bitrate can change the sound noticably. At what bitrate can we produce a perfect recreation from our perspective? The answer may come from analysing a spectrograph.
Sorry, this is a topic I'm a bit passionate about and I'm working on a project that considers these questions!
@JordiGH I've read alternative theories that it's 20kHz × 2 plus a bit because of quirks of the storage format used by studios. We'll probably never know for sure, much like the competing, incompatible theories as to why terminals were 80×25.
