We meet approximately once every two-three weeks during the Fall and Spring semesters to discuss the latest in computer music and sound synthesis. EMAIL LIST: If you would like to be added to our email list to be informed about future presentations, please send email to Tom Cortina (username: tcortina, domain: cs.cmu.edu).

Topic: User-adaptive playlist generation system for MP3 players
MP3 players carry more and more data while they are getting smaller and smaller. We may be facing the following question soon : how to navigate through thousands of tracks with only two buttons? I'm working on a user-adaptive playlist generation system. Spectral shape features are used to model pieces of music, the distance function to compute the distance between models is updated by user feedback - whether the user listens to the proposed track or skips it.

Topic: Concatenative Synthesis Using Score-Aligned Transcriptions
Concatenative synthesis assembles segments of pre-recorded audio to create new sound. In this variation, pre-recorded audio is labeled by aligning a polyphonic MIDI representation, essentially forming a symbolic transcription of the source material. Given a MIDI file to be synthesized, matching segments of MIDI describing the source are used to locate corresponding sound segments, which can be spliced to form the output. This technique is related to audio mosaics where similar spectral frames are substituted except that matching symbolic MIDI data allows for substitutions that are timbrally dissimilar yet harmonically and rhythmically identical.

Newell-Simon Hall 1505
Topic: New Computer Music Research
Roger will describe a new project in which he plans to enable a computer to perform in a semi-structured music performance such as a live jazz or rock band. He can demonstrate some signal processing and user interface support including a new pressure-sensitive foot-pedal/pad. Afterwards, we'll have a discussion to get suggestions from the group for some remaining problems.
