Also most things worth arguing over fall somewhere in the middle, and won’t have an absolute right answer. It sounds like the author has learned something important though.
Seriously! Every music theory blog post and video is like this. They're going to explain something like modes or maybe altered dominant scales, and they start out explaining intervals. Seriously stop, not from the beginning again! That's not your audience.
I like moving over for motorcycles. It's a little thing, but costs me nothing and is totally available as a recognition. Maybe it's like saying, "I see you." I had wondered if it was helpful. Now that you told me it's not necessary, I guess I'll continue doing it anyways.
I can add a bit of information to what might be behind this bug.
In MIDI, there are NOTE_ON and NOTE_OFF events, for when you press and release each key. The NOTE_ON has pitch and velocity parameters. The NOTE_OFF just has pitch parameter (maybe it has velocity as well I can't quite remember, it's off the point). So if you push middle C, it might look like this:
NOTE_ON 60 (middle C) 98 (velocity),
NOTE_OFF 60
Some keyboards never send NOTE_OFF events, instead they send NOTE_ON with velocity 0. On these keyboards, pressing middle C looks like this:
NOTE_ON 60 98,
NOTE_ON 60 0
Both are valid MIDI streams, and all stream processors should react appropriately to both. This app likely does not correctly map zero velocity NOTE_ON events to NOTE_OFF with the same pitch.
This error can be made for calculating the length of any curve. If you add the deltas in only one dimension, then you end up with a bounding box length measurement that doesn't follow the contours of the curve. It's a misuse of calculus, that can be done with or without the visualization.
These are neat! I guess you have to be comfortable with geometric proofs for them to really pop as obvious visual proofs, and certainly Archimedes was. I would have just started summing until it got close to 1/3, which is brutish by comparison to these beauties.
> that’s why CD music had a sample rate of 22000 Hz. Modern sound cards however tend to use sampling rates twice as high - 44100 Hz or 48000 Hz or even 96000 Hz.
Not exactly the point of the article, but this is all sort of wrong. CDs use a sample rate of 44.1 kHz per channel, not 22 kHz. I'd hazard this cuts down on rounding errors from having only one sample per 22kHz range. DAT used 48 kHz I believe to align evenly with film's 24 frames per second. 96 kHz is commonly used for audio today, and the additional accuracy is useful when editing samples without producing dithering artifacts within human hearing range.
> It is the mark of the marvelous toleration of the Athenians that they let this continue for decades and that it wasn't till Socrates turned seventy that they broke down and forced him to drink poison.
I've noticed this with movies. If a movie is being advertised a lot, it's usually a bad movie. Why else are they trying so hard?
The opposite happened with the Matrix. I think I saw 1 bus stop poster for it, and didn't know what it was until multiple people at work said, "you have to see it!" Too bad they never made a sequel.
