I haven’t posted in a while, as other projects have kept me busy, but it’s time to return to this long journey. These pages have actually covered a lot of territory, but the end goal is still a bit in the distance. And the goal remains the same: developing the hardware and software that we…

This is a preview of some upcoming projects. First, I’m still interested in a project that requires no custom hardware development, so when I saw the new 4-channel JAB4 DSP/Bluetooth amp from Wondom, I couldn’t resist. I’ve got a JAB4 board running in one of those PGA2311 preamp cases with an ESP32 CPU board for…

Long time, no publish…but the logjam is finally starting to clear. It took a lot of work to move “to the country”, but the garage is done, the wife’s greenhouse/nursery is mostly done, and electronics projects are starting to show up on the desk again. I’ve finally got some software that can be used as…

But in spite of time spent painting, refinishing floors and replacing cabinets and fixtures, there has been steady software “refactoring” for the ADAU1701 code. As noted in other posts, my engineering background is more hardware and…

Things are moving slowly in Audiodevelopers land, as we are working toward selling our house in Reston VA, and that means a lot of repairs and refurbishment that keeps me busy and away from electronics. But I’ve been trying to update this site with new content at least once a week (or more often if…

I made some updates to the stereo 3-way Part 2 page, and will be adding more in the next few weeks. However, the next update will be the software page, as I finally made a stand-alone version of the tool to process the SigmaStudio output files. This tool creates two files needed for the Arduino…
