Audio Signal Processing

Project Type/Degree:

Computer Science and Software Engineering


Description:


A project to extract and manipulate audio signals. Then to analyze patterns
and frequencies so that a piece of music in a CD
-
format can be manipulated to

sound like a vinyl using pattern matching.

The main aspect of this project is to
explore different transformation methods of singal processing in real
experiments.


Preliminary Preparation:


1.

Reading about fourier transformation


2.

Learning tools such as M
at
Lab


Minimum Objectives:


1.

Read
an audio file

likely in .wav format

2.

Extract
ing

signals

and visualise them with software tools or manually written
code

3.

Mixing signals back into a machine
-
playable format


Intermediate Objectives:


1.

Use existing patterns to m
anipulate and transform signals and explore
transofrmation methods like Fourtier transformation, wavelets or statistical
analysis.

2.

Study transformation methods to improve sounds of replay of CDs.


Advanced Objectives:


1.

Extract patterns from the audio sourc
es

2.

Studying the algorithms for signal transformation

3.

Visualisation of the manipulation process so that through a front end, a user
can manipulate the signals manually.
