Music Note Analyzer

Lab Partners: Peng Zhao and Gautam Mohan

For the final project in Digital Signal Processing, my lab group and I utilized Matlab to collect audio data and subsequently analyze to determine the frequencies produced by musical instruments. In particular, this project examines the accuracy in which we can perform spectral analysis to accurately exhibit the right musical notes produces by pianos and stringed instruments. It was found that for singular, isolated notes, direct spectral analysis can accurately reveal the right notes played by a piano, but had mixed success with a plucked stringed instrument, like a guitar. Chords were found to be impractical for decomposition without additional mathematical manipulation.
