Digitizing the Collection
WAV files of Mulligan's interviews were made from original source tape by Jon Newsom. Sound recordings of Mulligan's music were digitized by IHAS staff as WAV files from cds and lps. MP3 streaming files were then created from the WAV files. The EQ was adjusted with Sound Forge 5.0. The files were de-clicked, amplified, and beginnings and ends faded using Cool-Edit Pro 1.0. The derivative files were generated using Sound Forge 5.0. with the MP3s at 96K.
Manuscript scores in the Mulligan Collection were scanned by the ITS Digital Scan Center. An uncompressed TIFF scan of the original archival item with no compression was made. High resolution scans were made in color, with a few exceptions, at 24 bits-per-pixel and 300 dpi using the Phase-one FX camera. Derivative Truecolor images were made from the TIFF files by Library of Congress Network Development staff. The digital images online are jpeg images (quality level 80) in 5 sizes with an average compression ratio of 10:1 (the compression ratios may vary slightly depending on the size of the derivative).
The finale files for the score of "K-4 Pacific" were made by David Morse and Alan Gemberling at the University of Idaho.
Photographs from the Mulligan Collection were scanned by Lobsang Tshering as JPEG images. Derivatives were made by the Network Development team at the Library of Congress.
