Karaoke Callout
Karaoke Callout is a karaoke dueling game developed by David A. Shamma and Bryan Pardo at the Interactive Audio Lab at Northwestern University. It is an example of a game with a purpose. Its purpose is to help train the Tunebot database by providing the system with more query to target matches. The game was first developed and released in 2006 for the Nokia phone. The Interactive Audio Lab used this game to help train the Tunebot engine in preparation for research on improving the search engine. In the spring of 2009, Karaoke Callout expanded to a web-based game. It is also currently being developed on the iPhone to once again provide users with mobile play. In gameplay, player 1 selects a song from a list of available songs that already exist in the database. Then they sing his version of the song. After player 1 is satisfied with his performance, the system provides him with a score. Then the player has the option of "calling out" a friend. This means that they challenges their fr ...

Northwestern University
Northwestern University is a private research university in Evanston, Illinois. Founded in 1851, Northwestern is the oldest chartered university in Illinois and is ranked among the most prestigious academic institutions in the world. Chartered by the Illinois General Assembly in 1851, Northwestern was established to serve the former Northwest Territory. The university was initially affiliated with the Methodist Episcopal Church but later became non-sectarian. By 1900, the university was the third largest university in the United States. In 1896, Northwestern became a founding member of the Big Ten Conference, and joined the Association of American Universities as an early member in 1917. The university is composed of eleven undergraduate, graduate, and professional schools, which include the Kellogg School of Management, the Pritzker School of Law, the Feinberg School of Medicine, the Weinberg College of Arts and Sciences, the Bienen School of Music, the McCormic ...

Game With A Purpose
A human-based computation game or game with a purpose (GWAP) is a human-based computation technique of outsourcing steps within a computational process to humans in an entertaining way (gamification). Luis von Ahn first proposed the idea of "human algorithm games", or games with a purpose (GWAPs), in order to harness human time and energy for addressing problems that computers cannot yet tackle on their own. He believes that human intellect is an important resource and contribution to the enhancement of computer processing and human computer interaction. He argues that games constitute a general mechanism for using brainpower to solve open computational problems. In this technique, human brains are compared to processors in a distributed system, each performing a small task of a massive computation. However, humans require an incentive to become part of a collective computation. Online games are used as a means to encourage participation in the process. The tasks presented in the ...

Tunebot
Tunebot is a music search engine developed by the Interactive Audio Lab at Northwestern University. Users can search the database by humming or singing a melody into a microphone, playing the melody on a virtual keyboard, or by typing some of the lyrics. This allows users to finally identify that song that was stuck in their head. Searching techniques Tunebot is a query by humming system. It compares a sung query to a database of musical themes by using the intervals between each note. This allows a user to sing in a different key than the target recording and still produce a match. The intervals are also unquantized to allow for other tunings besides the standard A=440Hz, since not many people in the world have perfect pitch. In addition to note intervals, Tunebot compares a query with potential targets by using rhythmic ratios between notes. Since ratios between note lengths are used, the tempo of the performance does not affect the rhythmic similarity measure. Queries and ta ...
