The seminar is devoted to changing current topics in audio signal processing. In fall 2010, the topic of the seminar will be virtual analog audio processing. The seminar will focus on the real-time simulation of analog audio equipment, such as filters, synthesizers, and amplifiers. The language of the seminar is English.

Teachers

• The seminar is organized by Prof. Vesa Välimäki.
• Contact: S-89.3580@acoustics.hut.fi

A tentative list of topics for seminar papers:

1. Cross-over networks for digital loudspeakers
2. Graphic and parametric equalizers
3. Tone stack modeling
4. Resonant filters in sound synthesis (linear & non-linear)
5. Tape-based delay units
6. Spring reverberation units and their modeling
7. Plate reverberators and their modeling
8. Telephone sound effect
9. Analog and digital flanging and phasing
10. Bucket-brigade circuits and their modeling
11. Physics-based analog nonlinear circuit modeling (amplifiers, fuzz boxes) (P)
12. Measuring the response and distortion of analog systems (P)

The basics of acoustics and digital signal processing, such as the courses S-89.2300 Sound and Voice Technology and T-61.3010 Digital Signal Processing and Filtering, or their equivalents.

Book chapters, papers from journals and conferences. Examples on online material:

• DAFx Web Page (first select the year of the conference; papers accessible through the proceedings link)
• AES On-line Electronic Library (direct link that works from the campus). Papers can also be obtained from the Acoustics Lab Library.
• Engineering Village 2: campus access only, search for "sound analysis" and refine.
• Google Scholar: a great tool for searching academic publications (shows patents, too).
• Google Patents: a great tool for searching US patents.

You can choose either "S-89.3580 Audio Signal Processing Seminar" (3 cr) or "S-89.4820 Postgraduate Course in Audio Signal Processing" (8 cr). There are differences in requirements and the amount of work between the two courses.

The seminar (S-89.3580) is targeted for students working for the Master's degree in acoustics, audio signal processing, or digital signal processing. The requirements are attendance, learning diaries, seminar paper, seminar presentation, and peer feedback.

The Postgraduate Course (S-89.4820) is for students with a Master's degree. On top of the seminar requirements, they will carry out a special assignment and write a report.

• The seminar will start on Friday, Sept. 10, 2010 at 9.15 in room I346.
• Student presentations will be given during Teaching Period II (tentatively only on Nov. 12, Nov. 19, and Nov. 26).
• Please browse Noppa.

The students will discuss the seminar topics and plan the contents and coverage of their papers and presentations in small teams. However, within the team, each student will write his/her seminar paper and presentation slides individually. For each team, a team leader will return the draft versions of the deliverables (papers and presentation slides) of his/her team and compile the team member's presentation slides into a single slideshow. Student presentations will be given during Teaching Period II (tentatively only on Nov. 12, Nov. 19, and Nov. 26).
