OK, at the risk of sounding completely stupid?

Why do people listen to music with high sampling frequencies?
What is 88k+ providing them?
I understand why you might record at a high sampling rate, but why keep that for playback?

Looking through the FAQ, there are threads from 2003 that point out that the sampling frequency and bit-dept work in tandem. So the quantisation error of 16bit at 44.1k has the opportunity to be corrected sooner at a higher sampling rate, so in some ways is like a dithering pattern.

However given noise introduced in the analogue systems required to listen to music, a SNR within a 16bit signal of ~96dB seems pretty good.

So assuming that speakers struggle to produce the sounds that a 192k sampling frequency allow (eg 96kHz) and assuming that 16bits were sufficient when compared to the analogue equipment in the system, what have I missed in these high sampling playback formats?

People are selling music in high sample rates and bitdepths because enough people believe it sounds better to make it marketable (at least in a niche market!). Whether it actually sounds better or not is kind of irrelevant.

Where multiple versions are released, it can also be the place where a less compressed master is used, and/or more information/artwork/etc are included etc - or sometimes not. It's a nice excuse to charge more for these features. Just like Sony used to use better masters for making gold CDs in the 1990s. They'd sound just as good on a normal CD, but there'd be less excuse to charge extra.


The audio industry, which released a format good enough for all possible two channel music recordings in 1983 and managed to sell all the music from the past 100 years all over again in that format, is now looking on in envy at the film industry which has managed to pull the trick three times: VHS, DVD, and now BluRay. The crippled audio industry is desperate to pull the same trick again.


In recording studios, a lot of it is Emperor's New Clothes - and a lot of it is "why not?". There's no meaningful cost differential to working at 24/96 than 20/48. No one in a real studio worked at 16/44.1 during the last 20 years anyway.

Cheers,
David.
