Audio Signal Generating and Processing Project
- Abstract -
This project is intent to analysis different musical instrument's sound, and try to create artificial musical instrument sounds to play a piece.
First, by looking at the Fourier domain, one can and measure the amplitude of each harmonics. The intention is trying to produce similar amplitude harmonic cosine functions, and mix all the waveform together to construct a simulated instrument voice.
- Procedure -
First a couple of sound files are inspected. Particularly this single note piano sound was used. Take the FFT in MATLAB, the frequency domain of the graph looks like this.
