Spring

This project aims at implementing a VST plugin that tracks the tempo of a musical piece in BPM (beats per minute) in real time, namely the RealTime Tempo Tracker plugin. The implementation of the RealTime Tempo Tracker plugin comes in two parts: onset detection and measuring the tempo using a Hidden Markov model based on onset data. The plugin takes some waveform as input via a microphone or a stereo mixer. Then Fast Fourier transform is applied on windows of the waveform to track the change of the power spectrum over time.

Music is an integral part of human life. We wanted to do a project on music, and we wanted to do something fun. In the first part of our senior project, we try to find the song that user records on his/her phone. We use Fast Fourier Transform, peak finding, hash generation and audio matching with the help of their fingerprints. Next semester, we are going to implement a system that can be used to change the instruments of Turkish Classical Music songs. We think it would be fun to change Kanun to Electric Guitar or Ney to Saxophone.
