Open Access Publications
Advancing Research Through Open Access Publishing
Discover how AES Open Access publications expand the reach of audio engineering research, making scholarly work freely available to the global community while supporting knowledge sharing and innovation.
What is Open Access?
A growing number of countries and funding bodies require Open Access to the results of publicly-funded research. The AES OA policy explains the options available to authors, and also deals with archiving/preprints.
If an AES paper has been made OA it will have the OA logo next to it and will be freely downloadable from the AES E-Library by anyone, even if they are not an AES member or E-Library subscriber.

If a convention/conference paper is made OA, and later submitted in revised form to the Journal, the author has to pay the difference between the APC of a Journal paper and the APC of a convention/conference paper before it can be published in the Journal.
