Convert Sound Files in Audacity by Mike Barela
Small microcontroller audio projects are designed to play very specific types of audio files. If your music sample is in MP3 format, or 44KHz .wav or if you have grabbed a sample from a source (or the Internet) and do not know how it was encoded, you'll want to convert it to the right format.
This way you will get the best sounding audio, and it'll make using audio with your code painless!
This page will show how to convert your sound file(s) into PCM 16-bit Mono WAV files at 22KHz sample rate, which is usually best for the current crop of microcontrollers which take WAV files and play them on a speaker.
Currently, we are recommending two ways to convert the files: via use of the program Audacity or via iTunes. Other software may do similar conversions, just remember the parameters above when you do the conversion.

Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module.
The DFplayer mini is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. The module can be used as a stand-alone module with attached battery, speaker, and push buttons or used in combination with a microcontroller or development board like the Arduino, enabled for RX/TX (Serial) communication, thus through simple serial commands we can play music and perform other functions like playing the next and previous song, shuffle, pause the song currently being played etc. The module comes with an SDcard slot and supports both FAT16, FAT32 file system.

Adding sounds or music to our project will always make it looks cool and sounds much more attractive. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker. In this article I will show you how easy it is to Play music/add sound effects using your Arduino Board. Thanks to the Arduino community who have developed some libraries to build this in a fast and easy way. We have also used IC LM386 here for amplification and noise reduction purpose. [Gust MEES] GREAT music quality!!

Oskitone’s new and improved OKAY 2 is a mind-blowing DIY synth that you can 3D print and put together on your own. Hone your 3D printing and soldering skills with this sweet musical instrument and let the sounds sweep you away!
Looking for a new musical instrument to play? Why not use your 3D printer to create a synthesizer that is completely tailored to your style? Well, we’ve got a great project for all the musically-minded makers to take on over the weekend.
Last year, the San Francisco-based one-man musical instrument studio Oskitone released its first version of the OKAY synth, and has since refined the concept in a variety of ways. The new and improved OKAY 2 is an analog, monophonic, square wave synthesizer that is largely made up of 3D printed parts. It was designed on OpenSCAD and EAGLE by a man named Tommy, who is in charge of Oskitone.

Many teachers shy away from including music in their classrooms because they presume they need musical training to use music as a teaching tool. However, there are multiple ways to implement music in the classroom that don’t require any training.
Classroom Strategies
In the early grades, transitions are a little harder to set because the students are still learning what the concept of a minute is and what one feels like. A song can improve transitions because it becomes a behavior cue: Students grow accustomed to the length of the song or part of a song and internalize the time they have to move on to the next task, which helps them begin to take responsibility for their own learning.

Playing music is the brain’s equivalent of a full body workout,” says educator Anita Collins in a TED-Ed video on how playing music benefits the brain. Playing music requires the visual, auditory, and motor cortices all at once and since fine motor skills require both hemispheres of the brain, the act of playing music may strengthen the bridge between the two sides. In studies comparing playing music to other activities, including other forms of art, playing an instrument is uniquely powerful for the brain.

The Chorus to Remember
Music can make a huge difference in your workday. Feel free to crank up the volume if noise has you working like a snail, you've got a case of the Monday's, or you've got something mundane or familiar to do. Ideally, though, make your playlists out of songs you already know, and if your tasks involve any sort of linguistic processing, focus on lyric-free options. Lastly, if you have something to learn, pump up your mood with music before you get started.

Songs and rhymes can be used to remember all kinds of information. A study just published in the journal Memory and Cognition finds that adults learned a new language more effectively when they sang the words instead of spoke them. Even great literature is susceptible to this treatment. Book Tunes, a collaboration between educational entrepreneur Jonathan Sauer and hip-hop artist Andy Bernstein (he performs under the name Abdominal), turns long, wordy books into compact, catchy raps, spoken over an insistent beat.

Remember the days when you were in school, and you studied your tail off for an exam? You celebrated when you received your grade only to find out that one of your classmates, who had partied the night before, blew the socks off the exam because he had gotten a hold of the test questions beforehand.
Well, you thought that after you graduated, you had left all that baggage behind. Then you find out that these same characters are soaring through the corporate ranks because — you guessed it — they’ve learned how to “play the system.”
Well, I’ve got a message for these counterfeit superstars: If you think you can bluff your way through life, you’ve got something coming.
Eventually, people see right through these shortcuts to success. In fact, these counterfeit superstars are living on borrowed time. The day will come when their ways will come back to bite them. GOTCHA!
Despite the fact that the majority of people play by the rules and try to do the right thing, there are a number of bad actors in every organization who have no problem advancing their careers on the backs of others.
