The Drexel University Audio Archive’s mission is to:

Serve students cultural literacy by providing instruction, access, and research opportunities in music, music production, audio preservation, asset management, intellectual property rights, and interdisciplinary collaboration.

Serve the community by preserving its recorded music history, advocating its significance, and protecting its valuable recorded materials.

Serve the University and Music Industry Program by creating a vibrant student and faculty resource for collaborative projects and research.

The Drexel University Audio Archives is home to the Sigma Sound Studios Collection, a historic collection of approximately 6500 master audiotapes documenting the studio’s pop, soul, disco, and R&B recordings that became known as “The Sound of Philadelphia”.

The collection was donated to Drexel University for storage, preservation, and research. The Audio Archive is currently working to preserve the original tapes, migrate the audio to a digital format for research access, and archive data for long-term storage.
