Project work and final exam


This is a basic course on audio and speech signal processing. The course introduces what are audio signals, their properties, and the most common ways they are processed. It introduces the basics of human hearing, in order to develop understanding how humans perceive audio signals. It presents selected modern applications of audio signal processing. After the course, the student -Can design and implement algorithms for processing audio and speech signals using some common programming language -Can take into account the properties of acoustic signals and human hearing in the design of audio signal processing systems. -Can analyze and use the most common audio signal representations. -Can explain the main principles of common audio signal processing operations (equalization, dynamic control, perceptual audio coding), and understands where they can be used -Can recognize the most common modern audio processing applications such as automatic speech recognition. Can use these applications using existing software. Understands the possibilities and limitations of the applications.

Ohjeita opiskelijalle osaamisen tasojen saavuttamiseksi

The course is marked based on the partly the exam points, exercise points, and lecture diaries. The highest mark is given for correct exam answers that cover the depth and breadth delivered at the lectures and by actively solving the weekly exercise questions, and writing the lecture diaries. The threshold for passing the course is at about half of the maximum amount of points. An acceptable project work has to be returned by the deadline.
