The breadth of topics in signal processing continues to grow, propelled by advances in digital signal processing theory as well as in new application domains. At the 2011 IEEE ICASSP in Prague, the program committee revived the idea of expert overview sessions called “Trends,” which are summary talks authored by the IEEE Signal Processing Society Technical Committees and presented by their keynote experts. Starting with the September issue of IEEE Signal Processing Magazine, readers have an opportunity to access the summaries of the Trends sessions. In the September issue,

• Audio and Acoustic Signal Processing, by AASP TC
• Signal Processing for Networking and Communications, by SPCOM TC
• Signal Processing Theory and Methods, by SPTM TC
• Sensor Array and Multichannel Signal Processing, by SAM SP TC
