waveSDR

A macOS native desktop Software Defined Radio application using the RTL-SDR USB device.

<> Jun 2026 <>

Not sure if anybody is still following this project as I have left it on the back burner, so to speak, for way to long. I plan on jumping back in and adding features. The first feature I am working on is adding support for the HackRF One SDR radio.

Back from a bit of a hiatus in development on waveSDR, but before I start adding features to waveSDR, I plan on finishing my port of librtlsdr to a native macOS Swift framework. Follow the progress here: RTLSDR.Swift

I have started a simple build log which can be found in the project's root directory, more as notes to myself, but also as a means of thinking through my design choices and documenting them for future reference. Eventually my build log will become posts on my wordpress site.

At some future date I am going to migrate my domain name and all my web presence to a wordpress site. I have no idea as to when I will finish as dealing with my web presence never seems to be a high priority. In the mean time, if you wish to contact me about waveSDR, please feel free to drop me a comment here. (Sorry for the wordpress template, I prefer to write waveSDR code then build a wordpress site.)

If you are interested in my first prototype / proof-of-concept design, check out my first Youtube video. I also plan on putting together simple videos demonstrating the new features as I add them to waveSDR.

NB: This is purely experimental software. I am using this application as a platform for teaching myself macOS desktop application programming as well as DSP techniques. As it is, there are numerous sections of code where improvement is needed.

Features:

• RTL-SDR hardware
• Dynamic Device Detection
• Spectrum Analyzer
• Spectrogram
• AM Demodulator
• FM Narrow Demodulator
• FM Wide Demodulator (mono only)
• Mixer Tuning
• Swipe to tune
