Topic: How Csound Works: A Guided Tour
Speaker: Steven Yi
This presentation will discuss the design and operation of the music system Csound. A brief history of the programs design will be given, followed by discussion of the main parts of Csound: it's compiler and event system. This will be followed by discussion of various other features, such as its implementation of User-Defined Opcodes, Function Tables, Channels, and API. The presentation will aim to be of interest to users of Csound, as well as those interested in music synthesis systems in general.
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: Computer Music research at CMU, past, present, and future
Speaker: Roger Dannenberg
Topic: Second Screen: A television companion app for your smart phone
Speaker: Andrew Russell
Abstract: Second Screen is a better way to more efficiently split your attention between the TV and your Android phone. With one tap, it listens to and identifies what you're watching, then provides trivia and information about what's happening on screen. It continues to follow along with you as you watch and alerts you to important plot points, actors, trivia, insights, and more.
Topic: Jean-Claude Risset's distinguished lecture at CIRMMT from March 2011
"Music is meant to be heard: Perception is central in (my) computer music"
Risset worked at Bell Labs with Max Mathews in the sixties to develop computer sound synthesis, headed the Computer Department at IRCAM (1975-1979), and composed 70 compositions for orchestra, instruments, and digital sound. For his pioneering work in computer music, he received many awards including the first Golden Nica (Ars Electronica Prize, 1987).
Thesis Proposal: A Web-Based Cloud Digital Audio Workstation
Speaker:Haochuan Liu
The first way of playing back sounds on the web was via the bgsound tag, which let website authors automatically play background music when a visitor opened their pages. And then Flash was the first cross-browser way of playing back audio on the Web, but it had the significant drawback of requiring a plug-in to run. Today, with the rapid development of HTML5, Web Audio API has become a better way for processing and synthesizing audio in web applications. My work will concentrate on these three points as follow:
Javascript library for web audio
The first step of my work will be concentrated developing a high level Javascript library for using web audio. It will be the connection between Javascript programming language and the Web Audio API, which can be easily understood and used.
Web-based Digital Audio Workstation Implementing
The second step will be implementing a web-based Digital Audio Workstation using the Javascript library mentioned above. It will has features as following:
Multi-track recording from microphone, line input, USB/Firewire devices
Audio editing (cut, copy, paste, delete, splice and mix)
Built-in real-time audio effects
Audio mixing
Import and export audio file
Cloud Digital Audio Workstation
The most common problem people will have is that sometimes people have to work at different places and use different tools when they want to make music together. We can solve this problem using the Web-based Digital Audio Workstation. Audio files could be shared with any one you want and you can work together just by opening the same music project in the browser.
Thesis Proposal: Face Instrument
Speaker:Ziyun Peng
Controlling music/sound with face is not a whole new thing. There're experiments done with FaceOSC. However, there're more expressions I'd like to implement in my version of face instrument. For example, subtleness of one's breath and facial muscle movements.
Hence, Ziyun decides to make the Face Instrument which is a wearable music controller that keeps track one's five sense organs as long as breath and facial muscles. She'll also make a composition and performance for the device as the final presentation.

Thesis Proposal: CONVERSUS VITRA
Speaker: Can Ozbay
A New Class of Continuous Pitch Instrument using a PID Controller to control the pitch of a Hydrocrystalophone.
Conversus Vitra is a PID controlled continuous pitch Hydrocrystalophone. It consists of 4 wine glasses, 4 motors to spin the glasses, 4 friction sticks, a midi keyboard, and DC pumps to control the water level in the glasses.
Conversus Vitra uses a proportional-integral-derivative controller to control the pitch of the wine glasses, and as the player touches the midi keys, it changes the pitch of the glasses by pumping or sucking water from the individual glasses.

Topic: Music Cut and Paste: A Personalized Musical Medley Generating System
Speaker: Tina Liu
A musical medley is a kind of music piece that is composed of existing music excerpts. Manually creating medleys is time consuming because it is not easy to find out proper excerpts to put in succession and seamlessly connect them. In this work, a framework for creating personalized music medleys from users' music collection is proposed. Unlike existing similar works in which only low-level features are used to select candidate clips and locate possible transition points among clips, song structures and song phrasing are taken into account during medley creation.
