SingMySong - Arduino Spectrum Analyzer

  The Circuit

Inspiration

We began with the hopes of making a circuit that through Fourier Transforms and signal phase shifts cancels out noise and unnecessary surround sound,

What it does

Follows song pitches and presents an 8 bit rendition of it through a mini-speaker.

How I built it

-Takes an input through the microphone.

• Arduino transforms the input via Fourier Transforms to the frequency domain. The code is manipulated.
• Speaker outputs the 8-bit rendition of the song.

Challenges I ran into

• Employing and subsequently using the Arduino Fast Fourier Transform took up a lot of time, and therefore we had to settle for a pitch follower rather than a noise cancelling electronic circuit.

Accomplishments that I'm proud of

• Getting the Arduino to follow the input we give to the Microphone.

What I learned

• How to implement Fourier Transforms with Arduino.
• Soldering and unsoldering components to meet requirements.

What's next for SingMySong - Arduino Spectrum Analyzer

• Use it as a launchpad to make a circuit that cancels low frequency noise around the circuit.
