This series represents the final or nearly final drafts from a selection of unpublished writings by Richard C. Heyser. Submissions include articles originally intended for publication in AUDIO and Science magazines and the American Journal of Physics. In addition, this series includes Heyser's 1976 presentation, "It's a Great Day Tomorrow" and a variety of additional essay drafts. Overall, Heyser's unpublished writings reflect his philosophies behind the importance of measuring audio and his efforts to create mathematical and physics formulas for measuring sound.

In 2013-2014, Douglas R. Jones, professor of Audio, Arts, and Acoustics at Columbia College Chicago, edited and annotated part of Heyser's 1983 proposed series on time delay spectrometry (TDS) for AUDIO magazine.
