Why it was a mistake to assume "we cannot detect ultrasonic frequencies" Human hearing is not linear. The mistake people is assuming that the following would hold true for human hearing Listening(A+B) = Listening(A)+Listening(B) If that were true if Listening(B)=0 then...

How to pass sample-rate blind tests First you need to find a track that actually contain usable ultrasonic frequencies. I recommend finding some track you like that uses some recording of an acoustical instrument. You also need tweeters able to reproduce these high frequencies but luckily there...

Study: AstrZenica Vaccine drop to 61 effecasy, Pfizer Vaccine drop to 71% (delta variant) The study did show the vaccine to protect against infections but it would not be enough to reach Herd Immunity ndm.ox.ac.uk/files/coronavirus/covid-19-infection-survey/finalfinalcombinedve20210816.pdf...

Are dac/adc filters to blame? With CD quality you have a bandwidth of only about 2khz to implement filters that will cut out ultrasonics above the nyquist frequency. The 2*f*sinc(2*f*x) convolution filter will cut out all frequencies above a certain frequency and keep all frequencies below...

The Northern alliance leader is already talking about making peace with the taliban, a lot of people are probably hoping for way too much here, most likely is they will have to settle at controlling just a part of Afghanistan or that they will surrender completely.

Northern Alliance now supported by Tajikistan? This was reported via twitter: Earlier this morning, resistance forces got a first support from #Tajikistan helicopters have imported enough equipment, guns, full-ammunitions & foods. The morale of the resistance is high. We are grateful to our...

Significant results were observed for the comparison between files recorded at 88.2 kHz and their down-sampled 44.1 kHz version, p = .04, 1-tailed2. A tendency was observed for the comparison between files recorded at 88.2 kHz and 44.1 kHz, p = .1. No significant result were observed for the...

Looking into the meta-analysis showing high resolution audio to be technically superior The study did show that people without training had a very hard time hearing a difference but with training it was possible. Note that most of the studies included in the REISS 2016 meta analysis did not...

The loudness war Especially the CD version tend to be destroyed in the mastering process for the sake of loudness Typically a "high resolution" version will be mastered a lot better which will generally sound way better even if you convert it to CD quality.

CD quality allows you to reproduce frequencies below 22.05 Khz at a a signal to noise ratio of up to 96 dB, this is actually pretty good considering CD was format was released in 1982. It's actually very difficult to fully utilize the Signal to Noise ratio CD offers even today The topping...

NX gamer were unable to replicate this: The heatsink version of the SN850 is overpriced, third party heatsinks will cool it just fine for 40$ less The third party heatsink tested here was marginally hotter though.

Reddit: the Northern Alliance did a tactical retreat and then conquered even more No proper sources for the second claim was provided and the notion that them not even showing up to fight was tachnical could be just wishful thinking...
