+== Deep Learning and Opus ==
+
+Lossy networks continue to be a challenge for real-time communications.
+While the original implementation of Opus provides an excellent packet loss
+concealment mechanism, the team has continued to advance the methodology used
+to improve audio quality in challenge network environments.
+
+In Opus 1.5, we added a deep learning based redundancy encoder that enhances
+audio in lossy networks by embedding one second of recovery data in the padding
+data of each packet. The underlying algorithm behind encoding and decoding the
+recovery data is called the deep redundancy (DRED) algorithm. By leveraging
+the padding data within the packet, Opus 1.5 is fully backward compatible with
+prior revisions of Opus. Please see the README under the "dnn" subdirectory to
+understand DRED.
+
+DRED was developed by a team that Amazon Web Services initially sponsored,
+who open-sourced the implementation as well as began the
+standardization process at the IETF:
+  https://datatracker.ietf.org/doc/draft-ietf-mlcodec-opus-extension/
+The license behind Opus or the intellectual property position of Opus does
+not change with Opus 1.5.
