at least they are recognizing that there is no perceivable difference between 192kbps and 384!!  e: well depending on how high 384 is

Obviously if you go above 384k then your wings melt and you fall to the bottom of the ocean, your sound files turning into 2005 cameraphone concert footage

HenryEx posted:that's not kbps, my friend To expand on this cryptic answer, units are kilohertz. It’s the sampling rate. Mathematics proves there’s no benefit to sampling at more than twice the frequency of the signal, and since humans can’t hear much past twenty kilohertz, nothing is gained after forty kilohertz and change. e: I don’t know if this is a browser problem or a forums problem, but I find now that that link does not work.

If you double the sample rate, you double the quality. But if we double the doubled sample rate, quadruple quality!

It's worthwhile to pay attention to higher than 20khz just so we can avoid annoying animals and the rare humans that can hear higher freqs.

I think it's mostly historical, a combination of using values that were convenient for computers decades ago and choosing multiples of existing conventions to extend the series.

Platystemon posted:To expand on this cryptic answer, units are kilohertz. It’s the sampling rate. There is, though: Your presample filters don't have arbitrarily steep response, so if you don't want to roll off the signal at the Nyquist limit you sample at more than twice the frequency of the signal to give your presample filters room to work. We typically 5x oversample at work, so if the stress engineers want to see 50 Hz data we're sampling our strain gages and accelerometers at 250 hz. If we only sampled at 100 Hz there'd be attenuation of the 50Hz signal they want to observe (our filters are basically 6-pole Butterworths). CDs are sampled at higher than 40 kHz for the same reason. Oversampling also lets you improve SNR. That said, sampling audio at 2822.4 kHz like SACD is fuckin' pointless and audiophiles are nuts. Phanatic has a new favorite as of 20:00 on May 31, 2021 |

Allow me to clarify: there’s no benefit to publishing at more than twice the frequency of the signal. There are good reasons to work with higher precision in the production process.

SACD is overkill, but I do want to make it clear that it's sampling at a depth of 1 bit so at least approaching the megahertz range is necessary for reasonable quality. Also apparently using 1 bit samples screws up dithering very badly? Huh.

You could be right but there's no way of knowing from that picture.
