Theodore Keep

Theodore "Ted" Keep was a co-founder of Liberty Records. In his role as chief of engineering at the label and afterward, Keep introduced a number of innovations to commercial sound recording.

During the 1950s, Keep provided the synchronization process that allowed Ross Bagdasarian to combine his speed-doubled voice technique with full orchestration on "The Witch Doctor" and the series of Chipmunks recordings. For the latter, Keep received Grammy Awards in 1959 and 1960. Keep's Liberty Studios was the first commercial recording studio to employ solid state mixing equipment, retaining its claim as "the world's only transistorized recording studio" into 1960.

Keep also brought innovations to electronic music. Working with the Richard Marino Orchestra, Keep combined custom-built synthesizers and audio signal processing circuits to achieve the unique sounds on the 1961 exotica album Out of This World. This release built upon Keep's stereo mix experimentation that lent a surreal quality to the early Martin Denny recordings.

Into the 1960s through 1980s, Keep chose to focus on television and film audio. Among the better known soundtracks he recorded were the John Williams compositions for The Towering Inferno and Jaws.

Keep is also known for lending his name to the character Theodore of The Chipmunks, and for choosing The Ventures to record the Hawaii Five-O theme.
