Maximum Likelihood Chord Detection
This project is to process input audio files and recognize one of 12 major chords, i.e., C, C#, … B. The whole project is mainly based on the FFT and the Maximum Likelihood methods, to find the three most likely notes in the input audio. Based on these notes, a decision is made about whether the file contains a valid chord and if so which chord it is. Piano triad chords were used to test the algorithm. The algorithm was implemented as the C program chordrecog which ran under Unix.
