The following website has some simulated jitter test tracks: What does jitter ACTUALLY sound like? There are seven versions of each sample. Three have periodic jitter, three have random jitter, and one is the original - untouched. In the samples we have 2µs (microseconds), 4µs, 8µs, 16µs...

Interesting opinion piece from the Scientific American: Why Doubt Is Essential to Science If people don’t understand how science works, they can’t properly understand how to think about new findings https://www.scientificamerican.com/article/why-doubt-is-essential-to-science/ ...As a...

I've just tried an AI writer called YouWrite: https://you.com/search?q=how%20to%20write%20well&fromSearchBar=true&utm_source=email&utm_medium=newsletter&utm_campaign=youwrite20220405 I fed it Revel Ultima Salon2 and got: Revel Ultima Salon2 is a professional hair dryer that is designed to...

I found the following in an old white paper from Lavry Engineering titled "20 Bit Equipment For 16 Bit Work?". It would be interesting to hear comments from the digital audio experts. Can you hear under the noise floor? The engineering definition of the "noise floor" is a measure of the total...

Interesting (though very basic) piece about concert hall acoustics: What makes the perfect acoustic, according to science? https://www.classicfm.com/discover-music/latest/perfect-acoustic-concert-hall-science/

The Topping D90SE shows issues when measured 1kHz @ -63dBFS but not @ 0dBFS. Wouldn't it make sense to expand the DAC measurements suite, and perform measurements of e.g. 1kHz, 10kHz and 20kHz at both -3dBFS and -63dBFS? And shouldn't the frequency range in intermodulation plots be expanded to...

Ready-made multi-way horn speakers (e.g. Cessaro, Avangarde, Odeon, Living Voice) tend to be extremely expensive. Marc Henry's KornHent (formerly known as La Grande Castine) is a 3-way model using the Le Cléac'h profile which can be had for around €14,000. It needs a complementary subwoofer or...

Interesting piece.

Hi-Fi News tested a bunch of USB cables and published catchy eye pattern measurements for each one of them (along with some subjective blabber). Those eye pattern plots show some differences between the different cables. How does one read an eye pattern plot? What does it tell us about the...

Interesting piece on the Analog Devices website about grounding and digital audio: Staying Well Grounded by Hank Zumbahlen Grounding is undoubtedly one of the most difficult subjects in system design. While the basic concepts are relatively simple, implementation is very involved...
