Laetitia Sonami (born 1957 in France), is a sound artist, performer, and composer of interactive electronic music who has been based in the San Francisco Bay area since 1978.

She moved to California in 1978 where she studied composition at Mills College in Oakland with Robert Ashley, David Behrman, and Terry Riley.

[9] These sensors measure various aspects of hand motion, speed, and proximity, allowing Sonami to send data to her computer to play and manipulate sound and light.

The signals from the glove are routed through the Sensorlab, a piece of hardware developed at STEIM in Amsterdam, and are mapped onto MAX MSP software running on Sonami's laptop computer, where her sounds are stored.

[13] She also has a body of work described as ¨live film,¨ developed in collaboration with video artist SUE-C (Sue Costabile), where the two artists manipulate photographs, handmade motor-driven collages, models, still lifes, remote control train-mounted cameras and assorted lighting and sound effects in real time while computers process the images and deliver them to the audio-visual system with custom software developed in Max/MSP/Jitter.

"[15] She has also made collaborative works with sound artist Paul DeMarinis, electronic music composer David Wessel, and choreographer Molissa Fenley.

In 2013, a new work ‘’ OCCAM IX’’ was composed for her by Eliane Radigue, and she premiered the piece at the San Francisco Electronic Music Festival.
