About

The Stanford Center for Computer Research in Music and Acoustics (CCRMA) is a multi-disciplinary facility where composers and researchers work together using computer-based technology both as an artistic medium and as a research tool. 

Pronouncing "CCRMA":
CCRMA is an acronym for the Center for Computer Research in Music and Acoustics it is pronounced "karma" (the first "c" is silent).
 

Areas of ongoing interest:
Composition, Applications Hardware, Applications Software, Synthesis Techniques and Algorithms, Physical Modeling, Music and Mobile Devices, Sensors, Real-Time Controllers, Signal Processing, Digital Recording and Editing, Psychoacoustics and Musical Acoustics, Perceptual Audio Coding, Music Information Retrieval, Audio Networking, Auditory Display of Multidimensional Data (Data Sonification), and Real-Time Applications. 

 

The CCRMA community:
Administrative and technical staff, faculty, research associates, graduate research assistants, graduate and undergraduate students, visiting scholars, visiting researchers and composers, and industrial associates. Departments actively represented at CCRMA include Music, Electrical Engineering, Mechanical Engineering, Computer Science, Physics, Art, Drama, and Psychology. 
 

Center activities:
Academic courses, seminars, small interest group meetings, summer workshops and colloquia. Concerts of computer music are presented several times each year, including exchange concerts with area computer music centers. In-house technical reports and recordings are available, and public demonstrations of ongoing work at CCRMA are held periodically. 
 

Research results:
Are published and presented at professional meetings, international conferences and in established journals including the Computer Music Journal, Journal of the Audio Engineering Society, the Journal of the Acoustical Society of America, and various transactions of the Institute of Electrical and Electronic Engineers (IEEE). Compositions are presented in new music festivals and radio broadcasts throughout the world and have been recorded on cassette, LP, and compact disk.
 

CCRMA affiliation:
The Center for Computer Assisted Research in the Humanities (CCARH), also located at Stanford. CCARH conducts research on constructing computer databases for music, and on creating programs that allow researchers to access, analyze, print, and electronically perform the music. This focus is complementary to research at CCRMA in several ways.

The Knoll

CCRMA is located on the Stanford University campus in The Knoll--a building that was refurbished in  2004 and 2005 to meet its unique needs.  For more information on the history of the Knoll and to see hisoric images, visit: https://ccrma.stanford.edu/knoll-renovation.

The Knoll facility includes a large space with multichannel sound for teaching, concerts, and acoustic experimentation, an adjoining control room/studio, a digital multi-track recording studio with adjoining control room, two additional studios with digital editing facilities, several work areas with workstations, synthesizers and speakers, a seminar room, an in-house reference library, classrooms, and offices. The building has been wired so that any office or workspace can connect with the underlying network. A gateway connects the network to the campus at large and also to the Internet.

Knoll Renovation

The Knoll was originally built to be the residence of Stanford President Ray Lyman Wilbur, who was elected on October 13, 1915. Architect Louis Christian Mullgardt (1866-1942), envisioned a monumental three-story, Spanish Gothic fortress, with wings extending at obtuse angles, embracing the knoll. In 1946, the building became home to the Stanford University Music Department and in 1986, CCRMA took over residence in this unique building, moving from the former Stanford Artificial Intelligence Laboratory. The Loma Prieta Earthquake in 1989 damaged much of the building, and the third floor was weakened to such an extent that it was deemed unsafe for occupants. For close to fifteen years, The Knoll was never completely reconstructed, and the third floor remained condemned.

A major renovation of the Knoll began in the summer of 2004, and was completed in August of 2005. The renovated Knoll provides state-of-the-art sound studios, a dedicated performance space, and "open-plan'' work areas. Historical aspects of the building were retained and revived through a plan that locates research and studio facilities where they work best and interfere least. The new building permits full-spherical loudspeaker arrangements in the new "Listening Room'', thus enabling new research in synthetic acoustical space. A 100-seat performance hall is located in one wing of the uppermost story to provide a venue specifically intended for contemporary music performance projects. The new hall accommodates larger audiences, allows better scheduling flexibility (reducing contention with classes) and incorporates the building's unique view of the Bay and surrounding hills. The renovation made the building whole and better adapted for teaching and research.

The University regained a significant landmark with improved public access. A new demo museum lobby incorporated at the entrance provides exhibits pertaining to the history of music technology. Concerts in the renovated Knoll, its historical architectural qualities, and the side-by-side interplay of art and technology are an exciting mix for the future.

Directions

CCRMA is housed in the Knoll

Please use the following directions in conjunction with the Stanford campus map or Google Map

via Caltrain

Take Caltrain to the Palo Alto station. Take Marguerite shuttle service (either B Line or Midnight Express, depending on time of day) onto the Stanford campus; shuttles meet each train. Get off the shuttle at Tressider Union. Walk away from the Union through the Tressider parking lot and cross Mayfield Avenue. A pathway to the left of Florence Moore Hall leads up a hill. At the top of the hill is Lomita Drive, with the Knoll on your left.

from 280

Exit at Alpine Road heading east. At the first traffic light, turn right onto Junipero Serra Boulevard. At the next traffic light, turn left onto Campus Drive West. At the stop sign, turn right onto Santa Teresa. Continue on Santa Teresa until the second stop sign, then turn right on Lomita Drive. Stay to the right on Lomita; the Knoll is at 660 Lomita.

from 101

Exit at Embarcadero Road heading west. As Embarcadero crosses El Camino Real it becomes Galvez Street. On Galvez, turn left at the first stop sign, onto Campus Drive. Follow Campus Drive to Mayfield Avenue; turn right on Mayfield (and follow it as it curves left). At the end of Mayfield turn left on Lomita Drive. The Knoll is at 660 Lomita.

from El Camino Real

Turn onto the Stanford Campus at Galvez Street. On Galvez, turn left at the first stop sign, onto Campus Drive. Follow Campus Drive to Mayfield Avenue; turn right on Mayfield (and follow it as it curves left). At the end of Mayfield turn left on Lomita Drive. The Knoll is at 660 Lomita.

from Foothill Expressway

Follow Foothill across Page Mill, where it becomes Junipero Serra Boulevard. Turn right onto the Stanford Campus at Campus Drive East. At the first stop sign, turn left onto Mayfield Avenue. Follow Mayfield as it curves left. At the end of Mayfield, turn left on Lomita Drive. The Knoll is at 660 Lomita.

Parking

Parking in front of and behind CCRMA is zoned for Stanford 'C' permits, Mon-Fri 6am-4pm (i.e., parking is free around the building all other times). The nearest visitor pay parking lot is at Tresidder Union (campus map and Google Map), off Mayfield Avenue. For more information about visitor parking on the Stanford campus, please visit the Stanford Parking and Transportation website.

Once You're Inside / Where is So-and-So?

There are three floors, but confusingly both the first and second are "ground floors": since it's built on a knoll the first floor is the ground floor on the front side (towards campus) and the second floor is the ground floor on the back side (away from campus). Among the rooms at CCRMA most public events take place in the Stage (3rd floor, #317), Classroom (2nd floor, #217), or Seminar Room (3rd floor, #315). If you don't know exactly where you're going, we recommend you come to central second floor area ("Grand Central Station", #211) or the central third floor area (Lounge, #313, which is also a nice place to sit if you need to wait a few minutes), where you can often find people who usually know where to find whomever you're meeting.
