Introducing RadioSonic and "RF in Slow Motion"

We're developing a source-available DSP learning platform called "RadioSonic" to be released this summer. To see more details of RadioSonic in action, see the recording of my presentation "RF in Slow Motion" here: https://sigprolabs.com .

This talk was originally presented as the opening presentation at the 2026 New England Workshop on Software Defined Radio (NEWSDR) and later as an invited talk for the IEEE Philadelphia Section (the linked recording).

We're also developing fun DSP courses based on this platform, with the first course "Digital Filters" to be announced later this summer. If you want to be on the notify list, email info@sigprolabs.com and put PILOT in the subject or body.

New England Workshop for Software Defined Radio

The FREE New England Workshop on Software Defined Radio (NEWSDR) event is taking place in Worcester on June 5th (with tutorials the evening prior). The deadline to register has been extended to this Friday, May 29. More info and register here: https://newsdr.org/workshops/newsdr-2026/

I'll be giving the opening presentation on using "RF in Slow Motion" for hands-on SDR education. Scaling the speed of light to the speed of sound enables a real-time hardware-in-the-loop experience for common SDR techniques and algorithms, using wavelength-consistent acoustics and very low-cost use-it-anywhere hardware.

The image shows 64-QAM transmitted and received acoustically through microphones; the raw constellation as received on the left, and post-equalization on the right (EVM improvement from 52.7% to 2.2%).

I hope to see you there!
