Teaching Period (valid 01.08.2018-31.07.2020): 

III-IV 2018 – 2019, 2019 – 2020 (spring)

Learning Outcomes (valid 01.08.2018-31.07.2020): 

Students will be able to describe the history, trends, and applications of digital audio signal processing, describe the concepts "dither" and "noise shaping", recognize and design digital filters used in audio signal processing, describe how the sampling rate of a digital audio signal can be altered, list sound analysis, synthesis, and effects processing techniques and their main features, explain basic principles and uses of audio codecs, describe what the concept "virtual acoustics" means, and apply the provided methods using the MATLAB software.

Content (valid 01.08.2018-31.07.2020): 

General overview, history, and applications of audio signal processing, dither, noise shaping, digital filters used in audio, audio-specific design methods for digital filters, sampling rate conversion, analysis methods for audio signals, digital reverberation and effects, 3-D sound and virtual acoustics, sound synthesis, audio coding and multimedia standards.

Details on the course content (applies in this implementation): 

  • Must know: history, trends, and development of digital audio signal processing; recognize
    and design digital filters used in audio signal processing; list
    sound analysis and synthesis methods and their main features; list
    effects processing techniques and their main characteristics; explain
    how different kinds of audio codecs
    can be used; describe
    what the concepts ‘virtual acoustics’ and ‘3-D sound’ mean; apply
    the provided tools with MATLAB.
  • Should know: how to use MATLAB to produce interactive audio and video demonstrations related to audio signal processing.
  • Nice to know: technical details of certain vintage and modern audio effects processing units, music synthesizers, and audio codecs.

Assessment Methods and Criteria (valid 01.08.2018-31.07.2020): 

Special assignment and learning diaries with exercises, or alternatively, special assignment and examination.


Elaboration of the evaluation criteria and methods, and acquainting students with the evaluation (applies in this implementation): Option#1 (active participation and demo)

  • Total max points for diaries and homework: 20
    (diaries) + 10 (homework) = 30 points
  • Max grade for the demo is also 30 points
  • Max points = 30 (diaries+homework) + 30 (demo) = 60 points
  • Your
    final grade will be 1
    (fair)…5 (excellent)
Option #2 (exam and demo)
  • If you will take the exam, the diary+homework
    points will be replaced with your exam points (max 30 points)
  • Max grade for the demo is 30 points
  • Max
    points = 30 (exam) + 30 (demo) = 60 points
  • Your
    final grade will be 1
    (fair)…5 (excellent)

Workload (valid 01.08.2018-31.07.2020): 

Contact teaching approximately 40 h, independent work approximately 93 h, total 133h

Attendance in some contact teaching may be compulsory.

Details on calculating the workload (applies in this implementation): 

Lectures, lecture diaries and homework correspond to 50% of the course workload. The course project (demo) is assumed to take 50% of the workload.

Study Material (valid 01.08.2018-31.07.2020): 

Lecture notes and additional reading to be announced in the beginning of the course.

Details on the course materials (applies in this implementation): 

Lecture slides are published weekly immediately after each lecture. They contain links to literature.

The exam material consisting of technical papers will be delivered to those who would like to take the exam. 

Substitutes for Courses (valid 01.08.2018-31.07.2020): 


Course Homepage (valid 01.08.2018-31.07.2020):

Prerequisites (valid 01.08.2018-31.07.2020): 

ELEC-C5230 and ELEC-E5600 or equivalent knowledge.

Grading Scale (valid 01.08.2018-31.07.2020): 


Registration for Courses (valid 01.08.2018-31.07.2020): 


Further Information (valid 01.08.2018-31.07.2020): 

Language class 4: English, can be passed in Finnish or Swedish on request

Details on the schedule (applies in this implementation): 

After the first lecture, which is reserved for introducing the course arrangements and for selecting a course work topic, there are 10 lectures, one per week. Each week has a different theme to which the three-hour lecture is related to. Each demo is presented as a part of a lecture to which it is closest to thematically. 

The current lecture topics are the following:

  1. History and future of audio signal processing
  2. Digital filters
    in audio
  3. Audio filter design
  4. Analysis of audio signals
  5. Audio effects processing
  6. Artificial reverberation and 3-D sound
  7. Sound synthesis
  8. Physical modeling
  9. Sampling rate conversion
  10. Audio coding
