Does your screenshot indicate that you have listened to Spotify in lossless-16/44.1?

No, it was a glitch in the app where the hi-fi logo appeared. Clicking on it led to the menu you can see above.

It just announces that they are ready and that it shouldn’t be long till they make the official announcement!

Thanks - very nice.

As a Spotify Connect user I am looking forward to testing this out.

The lossless-16/44.1 would fit perfectly into the NL distribution.

Hi Geoff,

Thank you very much for you response, I am looking forward to your blog post!

Also a word of appreciation for your blog in general, you provide some excellent material. I regularly refer my students to some of your articles.

All the best,
Frederik 

Hi Frederik,

Firstly, thanks for the kind words!

Don't expect the blog posting to come soon. It's no earlier than fourth in the list after 

• an article explaining Jurin's Law and capillary action, and how it applies to fountain pen feed design
• an explanation of variable reluctance pickups for the section on the MMC cartridge in the Beogram 4000c manual
• a description of the straight line engine turning attachment I'm making for my wood lathe...

However, here's a quick outline for the "high sampling rate" series of issues-to-be-discussed (in no particular order...)

• an explanation of the Nyquis / Shannon theorem, confined to the simplest case of an ADC -> DAC
  • including an intuitive example with a piano. Doubling the sampling rate is equivalent to adding one more octave on the top. There are as many "frequencies" in that top octave as there are in all of the other octaves below. That's logarithms for ya...
• aliasing
• an explanation of how any distortion in the signal processing creates aliasing "inside" the signal path
• quantisation of poles and zeros in the Z-plane, resulting in inaccurate filter behaviour at low frequencies - a "victim" of the sampling rate and the bit depth of the filter coefficients
• inaccuracies in filters' magnitude and phase responses above about Fs/4 (or Nyquist/2) as a result of the bilinear transform
• possible effects on the noise floor caused by changes in sampling rate - particularly in systems with a Delta-Sigma conversion between the analogue and LPCM worlds
• artefacts caused by poor (and sadly, ubiquitous) sampling rate convertors in the signal path
• possible side effects in systems with frequency-domain processing
• The basic stuff like bandwidth, block sizes, carbon-equivalent footprint of streaming data
• The ease with which labels can cheat, delivering 44.1/16 recordings in larger container formats just to look bigger than reality
• Warnings and pitfalls associated with doing A/B comparisons

There might be some more things to discuss that I'll think of when I get going on it. *However, as you can see there (and as I mentioned earlier in the thread) "I can't hear above xx kHz" is just one portion of that first point in a rather long list of issues to consider...

But first: capillary action!

Cheers

😂 - who knew caterpillars could design fountain pens!!

Of course! Caterpillars are very good fountain pen designers! You just have to make sure they get all the work done before they start cocooning...

It's threads like this that make me glad my main listening source is vinyl...

😕

Did you know that hairy caterpillars are rendered deaf by the noise they make when crawling over a vinyl recording? Strange but true!👍

On the plus side, they make excellent substitutes as record cleaner!

Just in case there are any hard-core audiophiles out there... this is a joke. Do not harvest hairy caterpillars for cleaning your vinyl... It will not make the sound less "anemic", nor will it add a "sense of dimensionality" hitherto unheard-of in this time-space continuum.

Indeed, and it should also be pointed out, in the interest of safety, that attempting to clean vinyl using the hairy caterpillar method should absolutely not be attempted if wearing nylon undergarments as the resultant spark could be life threatening (to the caterpillar, at the very least).

Yesterday's technology, I'm afraid, Geoff

I'm now using a trained flock of millipedes wearing special slippers for record cleaning. My blacks have never been so inky...
