ABOUT CARL'S WORK
Carl Haber is an experimental physicist developing new technologies for preservation of inaccessible and deteriorating sound recordings. A vast amount of the world’s cultural heritage has been captured on fragile or obsolete recording media such as wax cylinders; shellac, lacquer, and metal discs; and tinfoil. Collections of experimental, musical, ethnographic, and historic content in libraries and museums around the world can no longer be regularly accessed by the public and are in danger of being lost forever.

Using insights from his work on imaging subatomic particle tracks in high-energy physics experiments, Haber and colleagues developed IRENE (Image, Reconstruct, Erase Noise, Etc.), a non-contact method for extracting high-quality sound from degrading or even broken analog recordings on two- or three-dimensional media. A disc or cylinder is placed in a precision optical metrology system, where a camera following the path of the grooves on the object takes thousands of images that are then cleaned to compensate for physical damage; the resulting data are mathematically interpolated to determine how a stylus would course through the undulations, and the stylus motion is converted into a standard digital sound file.

Sensitive to the importance of cultural stewardship and archival institutions’ mandate to both preserve and provide access to these historic recordings, Haber has collaborated with archivists and researchers in the United States and abroad to test IRENE on a variety of recording media. The method has been used to successfully play several recordings for the first time, including an 1860 phonautogram, the oldest known sound recording of a human voice, and the only known recording of Alexander Graham Bell’s voice. Currently working to enable mass digitization by making the technology more affordable, portable, and flexible, Haber is poised to revolutionize the preservation of rare, damaged, and deteriorating sound recordings of immense value to our cultural heritage.

BIOGRAPHY
Carl Haber received a B.A. (1980), M.Phil. (1982), and Ph.D. (1985) from Columbia University. He has been affiliated with Lawrence Berkeley National Laboratory since 1986, where he is currently a senior scientist in the Physics Division. Since beginning research on the preservation and restoration of recorded sound in 2002, he has worked with archivists at the Library of Congress, the Thomas Edison National Historic Site, the Phoebe A. Hearst Museum of Anthropology, and the Smithsonian Institution, among others.

关于卡尔的工作
卡尔-哈伯是一位实验物理学家，他正在开发新的技术，以保存无法使用的和正在恶化的录音制品。世界上大量的文化遗产被记录在脆弱或过时的记录媒介上，如蜡筒；虫胶、漆和金属盘；以及锡纸。世界各地的图书馆和博物馆中收藏的实验、音乐、人种学和历史内容，已经不能被公众定期访问，并有可能永远消失。

利用他在高能物理实验中对亚原子粒子轨道成像的见解，哈伯和同事们开发了IRENE（图像、重建、消除噪音等），这是一种非接触式方法，用于从二维或三维介质上退化甚至破损的模拟录音中提取高质量的声音。光盘或圆柱体被放置在一个精密的光学计量系统中，照相机沿着物体上的凹槽路径拍摄数千张图像，然后对这些图像进行清理，以补偿物理损坏；所得到的数据通过数学插值来确定测针如何穿过起伏，测针的运动被转换为标准的数字声音文件。

Haber对文化管理的重要性和档案机构保护和提供这些历史记录的任务很敏感，他与美国和国外的档案员和研究人员合作，在各种记录媒体上测试IRENE。该方法已被用于首次成功播放一些录音，包括1860年的phonautogram，已知最古老的人声录音，以及唯一已知的Alexander Graham Bell的声音录音。目前，Haber正致力于通过使该技术更加经济、便携和灵活来实现大规模数字化，他准备彻底改变对我们的文化遗产具有巨大价值的稀有、受损和变质的录音的保存。

个人简历
卡尔-哈伯获得文学学士（1980年）、哲学硕士（1982年）和博士学位。(1982年）和1985年）哥伦比亚大学的博士学位。自1986年以来，他一直隶属于劳伦斯伯克利国家实验室，目前是物理部门的高级科学家。自2002年开始研究录音的保存和修复以来，他与国会图书馆、托马斯-爱迪生国家历史遗址、菲比-A-赫斯特人类学博物馆和史密森学会等机构的档案管理员合作。
