Given the amount of small portable devices nowadays, there are so many speakers hanging around. Audio processing algorithms, seemingly only for huge home theatre system, are definitely useful in this case.
Great overview. Regarding Bass boost (p.2), I used to believe that psychoacoustics-based bass enhancers needed at least two harmonics generated, the second and the third, in order to be any effective. Is just a frequency-doubling in the low-Hz region "good enough"? I guess myself that the answer depends on the application... like hearing aids or cell phones versus portable media players, etc.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
