The SPS blog aims to raise awareness about signal processing and Society-related topics to a general interest audience in an engaging, informal, and non-technical way. If you're interested in contributing to the SPS blog, please contact the SPS Blog Team at sps-blog@ieee.org for more information.
When you first hear about Audio and Acoustic Signal Processing (AASP) it’s likely you don’t think of the movies, music and modern smartphones that it gives life to. As a sub-category of signal processing, AASP specifically deals with the analysis, processing and synthesis of sound that has been either recorded by one or more microphones or artificially generated by, for example, a computer program or synthesizer.

It’s not uncommon to find that engineers and scientists are reluctant to change. Unlike new features on your smart phone, new ideas in engineering and science can be received with a cold shoulder and large doses of skepticism. For anyone in the field, the statement “this is the way we have always been doing it” is heard numerous times during engineering design sessions. Most engineering teams would rather spend their time designing an automatic screwdriver than designing a new screw.
For many of us, it’s difficult to recall a time when our mobile phones were too big for our pockets, or our laptops weren’t paper-thin. But it wasn’t long ago that disk drives – the technology that stores data on digital devices – were the size of a room. Today, while they’re more like the size of a credit card and still shrinking, the sheer amount of data we’re saving to them continues to explode.
It’s a data storage problem José Moura predicted – and solved – 20 years ago.

Our modern life takes place in a world that is full of sounds, images and videos. You probably wake up by listening to some relaxing tone on your phone, listen to some music while you go running, and send a voice message to say happy birthday to a close relative. Then, you probably receive a notification to check the cool photos your friend has just sent you from yesterday's party and, while you’re checking the news, a trailer from a wonderful movie appears on your screen. It’s still early in the morning and you’ve already experienced the ubiquity of our multimedia world.

Whether they know it or not, almost everyone in both the developed and developing worlds benefits from daily advances in signal processing. Our information age centers our activities around two key themes: ubiquitous connectivity and online social networking. And these themes are, in turn and not surprisingly, front and center themes in signal processing.
This change is already happening, and it will be dramatic and exciting! It will completely change how most of us think about data, and how we tackle science and engineering problems. With it will come a flood of new discoveries—advances in the sciences and in new technologies—that were never before possible. What is this revolution? How did we get here? Where is it going, and how is signal processing involved?
