I watched your very interesting video "Samplerates: the higher the better, right?" about sample rates for production, and the purpose of oversampling.
I have been a big advocate for mixing at 96khz and recording at the highest sample rate possible (96khz or higher), so this video was a bit of a revelation.
The example shown was recreating a sine wave at 'normal' rate of 48khz compared to 96khz, and the lesson was that the sampling process was able to recreate that 20khz tone perfectly with only two samples per cycle, and so higher samples rates are unnesessary, and in fact could actually make things worse. This is obviously the Nyquist Shannon sampling theorem in action.
My question is this, the example demonstrated this perfectly with a nice, predictable sine wave, but how does this work with a complex real-world wave form? How can a complex wave form be reconstructed perfectly with only two samples per cycle, and why would sampling at a higher rate not make things more accurate?
I ask because I am now re-assessing my approach of mixing at 96khz, because I am now questioning whether I am making things sound better or worse.
Given the issues of mixing at 96khz compared to 48khz, and just relying on plugins that employ oversampling to do their job, is it still better to record at 96khz (or higher) and then downsample to 48khz to work on, or just to record at 48khz in the first place?
In other words, is this video suggesting it's better to mix at 48khz but it's still better to record or generate sound at the highest sample rate available (vis-a-vis buying or streaming 'high-res' version of music). Or, are you suggesting there is NO benefit whatsoever in recording at a higher rate than 48khz?
I've heard people say there is no need to record at a higher rate because "you don't need to", or "it makes no difference", but I suspect often they're just saying that because they just can't subjectively tell the difference personally, but in fact they don't actually *know* for a fact.
Can you help please? Maybe Dan would like to make a follow-on video? :-)
