Wednesday, April 12
Newell-Simon Hall 2507

Speaker: Daniel Gaertner
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.

Wednesday, March 29
Newell-Simon Hall 2507

Speaker: Wei You
Topic: Technical Paper Discussion:
Warping Indexes with Envelope Transformas for Query by Humming

Wei will discuss the paper "Warping Indexes with Envelope Transformas for Query by Humming" by Yunyue Zhu and Dennis Shasta of NYU. Click HERE for a copy of the paper.

Wednesday, March 8
Newell-Simon Hall 2507

Speaker: Roger Dannenberg
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.

Wednesday, February 8
Newell-Simon Hall 1505

Speaker: Roger Dannenberg
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.
