Read full description

Speech, music, seismic vibrations, oil prices, and climate measurements are all examples of stochastic (random) signals. In this textbook—intended for individuals with prior training in introductory signal processing and introductory probability theory—we develop techniques to process such signals to extract useful information. We present case studies ranging from music to photographic images to oil prices to climate data to the motion of individual biomolecules. This textbook, as an interactive textbook ("iBook"), makes use of your device's ability to display dynamic information through films and animations and to hear the results of the techniques applied to music. At the end of every chapter there are homework problems ranging from easy to "olympic". We make use of your device's interactive capabilities to offer 59 laboratory experiments in signal processing. The experiments use the camera, the microphone, the speakers, and the graphical user interface. These experiments are not simulations; they are examples of real digital processing of signals in your device. In this time of at-home and online learning, this is the way to learn signal processing through study and experimentation.

Verdict

The call

The clearest difference is review sentiment: Kaemika at 100% against Stochastic Signal Processing's 67%. Kaemika also leads on rating (5.0 vs 4.7) and iOS requirement (8.0 vs 15.0). Stochastic Signal Processing's advantage is ratings volume (6 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Kaemika holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stochastic Signal Processing has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of Stochastic Signal Processing's written reviews are positive against 100% of Kaemika's.

UpkeepUpdate frequency

Stochastic Signal Processing ships an update every 5 weeks, Kaemika every 6 weeks. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
