Detecting Audio Transients (Example and Free Cross-Platform Software)

Wikipedia defines an audio transient as "a high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech". Here's an example that points out the transients in a short snippet of audio:

Using Dual MCP23S17 I/O Expander Chips with the Tiva LaunchPad

In a blog post a few weeks ago I showed how I had been using an I/O expander chip with the Texas Instruments Tiva LaunchPad to provide eight additional inputs using a single serial connection. I've managed to increase this to 32 inputs.

New Reading Material - Algorithms, Hardware, Haskell and More...

I've been wrapping up my rereading of classic C++ books mentioned in a previous post here and looking into, and starting, some new reading material recently.

Computer Organization and Design, Algorithms and Haskell

I don't like immersing myself in a single book for many hours a day, but instead I try and read a little bit (maybe 15-60 minutes) each day a…

My Awesome Phase Vocoder (Audio Examples and Free Software Download)

In the spirit of the blog post I wrote on Alternative Music Production Software a few weeks ago, I've been spending a good amount of time working on a phase vocoder lately. I'm happy to say I have an early working demo version that sounds quite good.
