Three views of a cardioid

An epicycloid, the envelope of circles, the envelope of lines.

How to draw a cardioid

Step 1: Draw x, equally spaced, points in a circle. You can find the angle by dividing 360 by x (in this case 360/30 = 12°). Assign a number to each point (starting from 0)

Step 2: For each point, draw a line to point №(point number*2). If you reach a number that is too high (for example 15, 15*2=30), then just subtract the number of points (30-30=0). This is a simplified version of the modulo operator.

You're done! The cardioid is the bean shape on the top. You can get more detail with more points

For anyone wondering, these animations were made in Pygame and recorded using pygame_screen_recorder.

miku fun fact #41

miku doesn't use the Shure SM41 Cardioid Dynamic Vocal Microphone

[thekidsfromyestergay]

hiiii i've seen you talk about gear before and mics in particular, so i was wondering what kind of mic would you rec to a just starting out vocalist?

Shure sm58 hands down. They're around £100 new but you can pick them up for decent prices used or on offer and they are THE vocal mic. Every single singer ever has used an sm58 live (yes including gerard), and if you're interested in recording too, they also sound pretty great for that! A slightly cheaper alternative is the SE v7, sounds basically the same. But if you're talking specifically recording and not live, honestly a focusrite scarlett studio is a good and easy beginning option.

i tried really hard to graph a butt on my own but just ended up flinging cosecants around for a hot second, gave up, remembered the name of the shape, and found this https://www.desmos.com/calculator/uvgpdczdn0

re: your latest tags about microphone husbandry, what are you supposed to do with mics that, when held even a couple centimetres away from your mouth, seem lower the input volume by about 90%? (like is it just a skill issue on my end, mic quality problem, or?)

I am not even a beginning expert but I would say you are not being loud enough for the mic tbh. they work by picking up the pressure of your sound waves, so you need to be making big (loud) waves! volume isn't something the mic is really supposed to change, you need an external mixer/monitor

I loved the reaction, but Peat sounded so weird by the end that I couldn't understand anymore TT_TT

oh, he is over-modulated to hell and back.

I think when he hit his chest, he probably accidentally swapped it from one mode to another. I think at one point in that video you can hear Peat's heart beating, the mic is cranked so high.

It's also possible that when the mic flipped into the neck of his shirt, it pinned the head of the mic against his sternum, and then the team who edited the reaction had to crank it up in the editing software to even try to hear his voice. But like, Peat would have felt that, it'd be uncomfortable, and he would have twisted it back, so I kind of doubt it.

We use a very very similar wireless mic to record casual promos for my Friday show, and the host knocks the sensitivity to hell at least every other time. I wish those things had a lock you could activate to stop that from happening...
