iJDSP is an application (app) that enables simulation and visualization of Digital Signal Processing (DSP) concepts and algorithms on iOS devices. This version supports speech and audio processing with improved microphone audio acquisition, processing and rendering.

This app has been developed for education purposes in the Signal Processing Laboratory of the SenSIP Center at Arizona State University.
iJDSP provides an intuitive multi-touch user interface; DSP simulations can be established as a block diagram using a simple touch-n-drop procedure. All functions in iJDSP are organized as graphical blocks that can be visually added to the main workspace. iJDSP has a rich suite of signal processing functions including signal generators, digital filters, pole-zero plot and frequency response viewer, FIR and IIR filter design algorithms, FFT, plot functions, a sound recorder/player, spectrogram visualizer, and many others.
Requirements: Compatible with iPhone, iPod touch, and iPad. Required iOS 5.0 or later.

Software updated to version 1.2 on April 2018 and is now compatible with the iOS 11. Several functions upgraded to run faster and smoother.
Ratings and Reviews
Love the open nature
I love the open nature of how you can build a DSP system with blocks that represent signal sources, transforms, filters, and analysis.
Could be better
If it had support for the new iphone screen format
Works well.. The interface is simple and intuitive.
With Family Sharing set up, up to six family members can use this app.
