Ray Li and SoundSpace opportunity

From Ray Li who visited Music 1421 with his “SoundSpace” interface:

Dear Musicians,

We are currently developing a gestural musical interface for live performance, called “SoundSpace.” Our interface consists of several motion-based musical instruments, as well as the ability to record and manipulate loops of these instruments. One of the instruments from SoundSpace is “The Aura,” of which you can see a video here:

SoundSpace will be showcased in a concert on Saturday, May 3rd at 7pm in Bailey Hall. We are seeking a musician to perform with the gloves at this event. We encourage all interested musicians to apply, though candidates with the following qualifications will be favored in our selection process:

1. Ability to quickly learn new instruments.
2. Ability to commit the necessary amount of practice time, esp. in the 3 weeks prior to the event.
3. Proficiency in multiple instruments, preferably including percussion, vocals, and some continuously-pitched instrument.
4. Preferably, experience with live looping

If you are interested in performing with the gloves, please send an email to RL396 AT by Friday, March 7th with the following:

1. A video (or two) which you believe best showcases your musicianship. If you have experience with live looping, please send an example of this.
2. A paragraph (or two) about your musical background, musical tastes (esp. electronic artists), and why you would like to perform with the gloves.

We look forward to hearing from you!

Ray Li

Network Drive problem

The Network Drive problem has been fixed in all studios. With it having been offline, please take an extra day to hand in this first assignment. You can access the drive from any of the three studio computers. If it is ever offline again, see the FAQ for how to mount it…very easy to do.

Studio B hand-in troubles

There appears to be a problem in Studio B (B25B) with seeing the Network Drive. Since the files for this first assignment are, for the most part, very short, it should be fine to attach or send them to me and/or you TA directly, just this once (see our email addresses on the class syllabus). To those working in other studios, please do hand-in your results normally as described in the assignment description.

We will fix the problem as soon as possible! Thanks to those of you who let me know.

Registration closed

NOTE: New user registrations can be requested via the Contact page as the open registration period for the Spring semester is now closed in order to inhibit SPAM.

Studio signup

A brief reminder tutorial for studio signup has been posted in the site FAQ. If you have further trouble, please ask.

Lecture 1 links online in “Class Materials”

Hello all,

The links and reference materials I mentioned as follow-ons to this morning’s lecture are online in the “Class Materials” section (found above under “Courses–Music1421…”). You will see these class-related posts only when you are logged in.


Lecture 1: Digital audio fundamentals

Following up on today’s lecture (1/28/13), here are some links of potential interest:

Ray Li’s Aura, SoundSpace, and related work

Ray Li, BS ’14 (Music 1421, 2421, Independent Study) and Michael Ndubuisi, BS ’14 (Music 1421), designed Aura (later evolving into SoundSpace), a new instrument that allows the musician to shape and control sound through hand movements.

SoundSpace uses electromagnetic sensors to track the exact position of the gloves in space. The motion of the musician’s hands can trigger prepared sounds, play different notes and add musical effects.

“We wanted to imagine sound as a tangible thing that you can hold between your hands,” Li said. “We’ve tried to create something that can basically do anything that you could do in a normal sound-editing computer program.”

The software for Aura has, more recently, been expanded into SoundSpace including recent performances with the Cornell Symphony Orchestra and as a solo instrument as with the demonstration of SoundSpace is below.

SudoGlove and SudoSynth

Jeremy Blum’s SudoGlove (also SudoSynth) is “a gesture controller that can be easily interfaced with hardware or software via a wireless connection. The glove implements an array of sensors plus filtering circuitry and mathematical analysis firmware to derive state values for each sensor and transmits them to an authorized receiver. I have used the glove to drive an RC car, to synthesize music, to manipulate openGL video, to control arbitrary processing software, and to control performance lighting effects.”

The instrument and its varied applications was featured in April 2011 on the Discovery Channel’s Daily Planet.

A complete summary, details of further uses, pointers to additional research and publicity, and links to code (Creative Commons License) can be found on Jeremy’s own (very thorough) page here.

A music-specific discussion of the development and application of SudoGlove/SudoSynth to performance is here.
