FM-Synthesis-Project

This repository contains MATLAB files used to simulate the instrument diagrams shown in "The Synthesis of Complex Audio Spectra by Means of Frequency Modulation* JOHN M. CHOWNING "

This was created and tested as part of the Project component of EC5.203 Communication Theory, Spring 2021, IIIT Hyderabad.

Category of Files:

1) Trial_<type_of_instument>.m

These files directly simulate and play the sound as given in the name and the amplitude and frequency spectrum will be plotted

2) Block.m

This file contains the main function Block() which is used to simulate any unit generator. It takes in input like so

x = Block(freq,ampl,string,dur); 

frequency and amplitude are used to create sinusoids and the variable string contains the type of intrument, and dur is the duration of the sound to be generated

3) BrassPlayer.m

Given a string of notes, it uses the function Notes2Hz.m to play a Brass generated audio clip. Each note plays for 0.6 seconds.

4) x<type_of_instrument>.m

These functions generate the amplitude or instantaneous frequency deviation plots/vectors

5) Miscellaneous

trial.m was used for experimentation
vecProd.m was used in the implementation of the Block function.
Notes2Hz.m used in BrassPlayer.m to convert a string of notes to just frequencies
Output.m was used to plot out and play the different audi files generated.
