Vybz
Overview
Our goal is to create a sound system that self-adjusts its output in response to the amount of noise in the room. This is an efficient way for a sound system to adapt to conversations, the environment, and other noises without the need for manual work. This application will consist of three main components: A microphone to gauge the level of noise in the room, a Raspberry Pi to analyze data and send signals to the speaker, and a speaker which produces the necessary output. It will maintain the atmosphere in the room and conserve the vibe of the room.

Objectives
- Gather resources (speaker, microphone(s), A/D converter, etc...)
- Configure the microphone with an A/D converter so the microphone's analog signal is transformed into a digital one
- The Raspberry Pi needs a digital signal to read
- Prime the Raspberry Pi to receive and analyze the digital signal using:
- Our own coding knowledge
- Newfound Python skills
- Libraries of code for the Fast Fourier Transform
- Use the Raspberry Pi internet capabilities to access music/songs to be played
- Connect the Raspberry Pi to the speaker in order to adjust the volume as a result of the input signal
- Develop a plan for a demonstration that does not impede on other's project but effectively displays our project
Challenges
- Learn how to program the Raspberry Pi using Python and skills from the tutorial videos
- Access and dissect coding libraries that may hold code that is useful but lies outside of our skill level
- Find and apply the Fast Fourier Transform to create sound profiles of the ambient noise and the speaker's music
- Establish a communication between the Raspberry Pi and the speaker
- Program Raspberry Pi to access a song/music database
- Work to develop an effective demo given the location, Lopata Gallery
Gantt Chart
Budget
- Raspberry Pi (Provided)
