The audible difference is mostly pre-echo and warbling noises, not low-pass filtering.

This appears to be visual comparisons of graphs of various automated measurements. Lossy codecs are designed to exploit weaknesses of human hearing, so the only way to test if they're working as intended is with listening tests. This i

There's no need to actively try to make the AI malicious. That's the default for any AI that's more operationally capable than humans and has some difficult goal. Humans can only hinder it, so the goal is better accomplished

I was listening to some of the LAME quality test samples[0] and I found that the hi-hat pre-echo test sounds worse at 160kbps than at 128kbps (LAME 3.100, -q 0). I thought it might be because of the different low-pass filter frequency, but

A 64ft organ stop goes down to 8Hz, but your DAC might not. Attempting to play extremely low bass too loud is an easy way to damage speakers/headphones, and most people don't have rotary woofers, so it's common for playback e

48kHz has the advantage of being an integer multiple of many common video frame rates, which makes video editing simpler.

What exactly do you mean by "see more than 60fps"? It's possible that 60fps video with full temporal antialiasing and low to moderate motion speed could fool untrained viewers, but if I'm allowed to move my eyes I can te

You don't need super high-end equipment to hear subtle details in audio, you just need reasonably good headphones. A few hundred dollars worth of headphones will get you quality that would cost tens of thousands with speakers and the r

Humans don't have 100dB dynamic range across their full hearing spectrum. We're less sensitive to high frequencies, which means you can apply high-frequency dithering to improve the dynamic range without adding audible noise. htt

Required bitrate depends on the music. With a modern version of LAME, 128kbps will be very difficult to ABX for solo vocals, but much easier in busy rock music (specifically, by listening to the decay of the cymbals). This is why variable b

There are two reasons to use WAV over FLAC in music production: you can load WAV files into your DAW faster; and WAV supports floating point, which means you never have to think about clipping until the final mastering step. Neither is rele

If you EQ your headphones, e.g. to match the Harman curve[0] to better replicate the sound of loudspeakers in a moderately treated room, you'll probably find they need a lot of bass boost. This means you have to turn everything down to

Motion blur can help compensate for low framerates if it's (approximately) physically accurate, i.e. temporally oversampled. This is how 24fps movies can look tolerable despite the ultra-low framerate: each frame provides more informat

The Metal Slug games are already at a disadvantage because they run at 30fps, unusually low for arcade games. All else being equal, lower frame rate gives higher input latency.

A lot of that smoothness was the lack of sample-and-hold blur on CRTs. Gaming LCDs now have modes that strobe the backlight to simulate this effect. Additionally, the importance of sample-and-hold blur declines as the frame rate increases.
