Imaging Lost Voices: High Resolution Optical Scanning of Historical Sound Recordings
Marjorie Shapiro, Professor
Physics
Applications for Fall 2024 are closed for this project.
Important collections of historical sound recordings exist in archives, libraries, and museums worldwide. Many of these items are delicate and cannot be played by normal means. In this research project we are applying modern optical scanning methods - confocal microscopy and high resolution digital imaging - in order to obtain detailed maps of the surface of these objects. We then apply image and signal processing methods to model the playback process 'virtually' in order to recover and restore the audio content. Among the collections we are studying are early experimental recordings created by Alexander Graham Bell, in the 1880's, field recordings from Yugoslavia from the 1930's, and Native American recordings from the early 20th Century
The methods and technology applied in this project include imaging, robotics, motion control, and image, signal, and statistical analysis. Students may participate in developing and testing real-time control and data acquisition hardware and software or in the development and application of software for data analysis.
This work provides a unique opportunity for undergrads to experience the research environment, and participate in a project which combines many modern methods and techniques in service to the greater community of scholars, researchers, and the public, concerned with cultural preservation. Please write 'IRENE' on your application if you are interested in this area.
Some funding may be available for students who are eligible for work study or LAEP. Please indicate if you are eligible and if you would like to be considered for such funding. Eligibility for work study will NOT be used as a criterion for selecting candidates
Qualifications: Some programming skill is preferred. Expect to work under the supervision of a senior research scientist around 9 hours per week on a regular schedule.
NOTE: Due to Lawrence Berkeley Lab regulations, we cannot consider any applicant who is under 18 years of age.
Hours: 9-11 hrs
Off-Campus Research Site: LBNL building 50
