The digital transfer of tape archives or sonic restoration for commercial release requires precision, care and accuracy.

PLANGENT-OPTIMIZED TRANSFERS
Airshow is the music studio provider of analog master tape transfer for Plangent Processes restoration services. Plangent processing brings unprecedented clarity and increased image depth and focus to master tapes using a proprietary technology to remove wow, flutter and other speed perturbations. We’ve written about the method here.

SONIC RESTORATION
Some of the most cherished reissues of recent years been restored at Airshow, including the GRAMMY-winning collections “The Anthology of American Folk Music” and “Screamin’ and Hollerin’ the Blues: the Worlds of Charley Patton.” Audio restoration – the nuanced, detailed application of noise reduction processes, click and pop removal, and distortion reduction – contributes clarity to releases of archival and historic material.

THE RESTORATION CENTER for AUDIO ARCHIVES
The Restoration Center is a suite of services to help cultural heritage institutions and record labels to digitize analog audio archives and make them accessible electronically. Digitization services include real-time transfer from cassette, disc, any open-reel tape format, and PCM and DAT digital sources. After digital conversion, files can be post-processed to enhance listenability for scholars or to a commercial standard for use in exhibits or release.

Archivists are welcome to send or bring a box of media and participate in a Discovery Day. Prospective Restoration Center clients are welcome to contact Ann Blonston in Boulder to discuss their project: 303-247-9035.
