I am a man who lives in Northern California. My interests are digital signal processing, C++ programing, music, illustration, history, sociology, and literature. Before retiring I worked as a software engineer, and later had a small website (www.creativedetectors.com) to sell a few pitch detection applications for music which I had created. Now being retired, I have decided to release the C++ source code for my Pitch Detection Engine within a free demonstration app called PitchScope Player . PitchScope Player is available on the web for free, and you can download the executable for Windows to see my algorithm at work -- detecting the notes of musical instrument solos upon mp3 files of your choosing. PitchScope Player is a MP3 player which can also do real-time note detection while you listen. The newly detected notes are animated upon a colored circular display while the Windows Midi Synthesizer plays the detected notes along with the music. The link below to GitHub.com will lead you to my full C++ source code for Windows, where you could compile and view how I perform real-time Pitch Detection upon polyphonic mp3 recordings. Some of my favorite books on Digital Signal Processing as it relates to the analysis of Music: Signal and Image Processing with Neural Networks -- A C++ Sourcebook , by Timothy Masters, John Wiley & Sons, 1994 C Algorithms for Real-Time DSP , by Paul M. Embree, Prentice Hall PTR, 1995 Digital Image Processing , by Rafael Gonzalez and Richard Woods, Addison-Wesley Publishing Company, 1992 (many of the DSP algorithms for the study of Image Processing are reused in the analysis of Audio and Music) Computer Imaging Recipes in C , by Harley Myler and Arthur Weeks, PTR Prentice Hall, 1993 Musical Applications of Microprocessors , by Hal Chamberlin, Hayden Book Company, 1985 The Music Machine -- Selected Readings from Computer Music Journal , edited by Curtis Roads, Massachusetts Institute of Technology, 1989 (this single book launched my extensive exploration into Pitch Detection) A 3 second Logarithmic DFT, created by my C++ code, from a Eric Clapton guitar solo on a polyphonic mp3 recording ©
