What are the Differences Between White, Pink, Brown And Blue Noise? #MusicMonday

We’re familiar with white noice, but how about pink and brown noise? As it turns out they all exist, they all have distinct acoustic profiles, and they all have different uses. More from Bobby Owsinski’s blog:

White is…pretty harsh sounding, and doesn’t represent too much of what we hear in nature, but it’s been found to be extremely useful of one thing – it’s masking effect…. Pink is used most often in audio testing because it closely approximates how we hear. The energy rolls off at about 3dB per octave, and the acoustic energy is equal in all frequency bands. In other words, it’s white noise with decreased high frequencies. Since our hearing is more sensitive to higher frequencies than lower ones, that makes the spectrum of pink noise excellent for acoustic tests like room tuning.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
