Free Book on DSP in Python

Think DSP- Digital Signal Processing in Python

This book looks great - it's a work in progress by Allen Downey, a professor at Olin College.  Every example includes Python code to perform the calculations as well as read and write waveforms.  Many examples use music so that should be valuable to readers of this blog and people who like to DIYDSP.  So go ahead and download the free PDF or read it in HTML.

Axoloti - Embed A Digital Modular Synth In Your Instrument

This is very special to me.  This is exactly what I have been looking to do with the digital music instruments I have been designing and building - Give them a modular synthesizer editor.

This is a software and a hardware project.  It lets you graphically edit a patch for a DSP-based music instrument, then upload it into a small circuit board.  That means you can put that instrument into a box with sensors and controls, make a digital guitar, tune it to sound just the way you like it and even put all kinds of digital effects on it!  It's a very difficult and important project and I am sure it will lead to very many interesting kinds of new instruments, songs, performances and possibly even genres of art!

Here are the specs:

• Two 1/4" jacks
• Stereo headphone output
• MIDI Input
• STM32F4 processor (168 MHz w/ FPU)
• USB
• Modular synth editor on Desktop
• Cross-Platform support (Lin/Win/OSX)
• Approximately $100 incl. shipping

I highly recommend supporting Axiloti on Indiegogo.  I look forward to working with it a lot in 2015!

Sketch a Filter from DSP Creations

Draw a filter by hand with Dr. Gerry Cain's extremely powerful tool, Sketch-a-filt. Listening to him, I am amazed at how incredibly intelligent and experienced he sounds with DSP!
