Course contents :
|
| Course description
Analysis and synthesis of audio systems and techniques. Real-time processing is an objective of this course, in particular through the programming of systems on a digital signal processor (DSP).
Contents
- Introduction to audio signal processing
- Description of the DSP that will be used during the laboratory sessions
- Conception and realisations (in the lab) of simple digital audio systems (FIR, IIR filters, delays, undersampling, quantification noise)
- Project
|
|
Learning outcomes of the course :
|
| At the end of this course, it is intended that the student will be able to:
- design audio filters and other simple digital audio systems,
- determine (with Matlab) the properties of these systems (stability, impulse and step responses, frequency responses, etc...),
- program the corresponding code in the C language, on a (floating-point) DSP,
- measure and test the properties of the realised system.
|
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| Introduction to audio and video techniques, Signal Processing, Systems (analysis and design). |
|
Planned learning activities and teaching methods :
|
| After a short theoretical introduction, this course relies mainly on laboratory sessions, consisting in the programmation of a DSP.
During these sessions, groups of 3 or 4 students will be formed, depending on the number of DSPs available. Exercises of increasing difficulty are proposed to the students who have first to conceive and analyse a solution, secondly to program their system on the DSP and finally to test its properties.
A teaching assistant will be present and help them in their works. Some exercises are concluded by a laboratory report.
Finally, each group will realise a project (different for each group), i.e. an audio application chosen among a list of proposals (equalizer, artificial reverberator, chorus and flanger, guitar chorder, etc...) |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Mostly, laboratory sessions (programming a DSP) with the help of a teaching assistant. |
|
Recommended or required readings :
|
| The learning materials and documents will be provided by the teacher (some of them on-line).
Suggested readings:
Zölzer U., DAFX Digital audio effects, Wiley (2008)
Zölzer U., Digital audio processing 2nd ed., Wiley (2008) |
|
Assessment methods and criteria :
|
| The assessment relies on:
- an evaluation of the laboratory reports,
- an evaluation of the final project report and its oral presentation.
During this presentation, each student will be evaluated individually. Questions are asked in english by the teacher, the student is allowed to answer in french.
The project report must be written in english.

Organizational remarks :
|
| 1st (autumn) quadrimester, Montefiore Institute B28.
The course is organized in english from the academic year 2014-15. |
