nrsc5-dui VS airspy-fmradion

From https://github.com/markjfine/nrsc5-dui#maps :

> Maps: When listening to radio stations operated by iHeartMedia, you may view live traffic maps and weather radar. The images are typically sent every few minutes and will fill the tab area once received, processed, and loaded. Clicking the Map Viewer button on the toolbar will open a larger window to view the maps at full size. The weather radar information from the last 12 hours will be stored and can be played back by selecting the Animate Radar option. The delay between frames (in seconds) can be adjusted by changing the Animation Speed value. Other stations provide Navteq/HERE navigation information... it's on the TODO 'like to have' list.

Is this an easier way to get weather info without Internet than e.g. Raspberry-NOAA and a large antenna?

and sometimes I use https://github.com/markjfine/nrsc5-dui when I want to see the weather and traffic maps . honestly they are worse quality compared to the weather network for local coverage but it is a neat demo

After a lot of searching and testing I came across the developer Markjfine and after trying to make nrsc5-gui to work well he decided to fork the project to nrsc5-dui. Nrsc5-DUI is a fork of a really old version of nrsc5-gui that is not dependent on python audio processing which caused a lot of issues with modern versions of nrsc5-gui. Like the old version, it still uses python, it's still licensed as GPLv3, and has a similar interface. However, Nrsc5-DUI has plenty of new features and improvements such as better audio processing, better channel switcher, more station information, the option to pull album art from Discogs (currently broken due to Discogs anti-bot), better map displays, cleaner code, and optimizations for Python 3.9.

I have a little hobby project where I record an FM radio music station using a SDR and then remove all the non-music portions for offline listening. I like the music selections the DJs pick, but I prefer not to listen to the DJ commentary and the advertisements.

I evaluated three methods of recording: analog capture from a standalone FM receiver, using this nrsc5 library to record the "HD" radio stream, and using an AirSpy SDR with this library: https://github.com/jj1bdx/airspy-fmradion

Recording the "HD" (what a misnomer) radio was nice in that there was no hiss or multipath effects, but in comparison to the other methods the digital compression artifacts became impossible to un-hear. It seems to top out at about 96 kbps

The airspy-fmradion library has some nice stuff in it to address multipath, resulting in the best audio quality of the three methods I tested.

I use https://github.com/ina-foss/inaSpeechSegmenter to identify which segments of the recordings are speech vs. music.

Alternatively, use airspy-fmradion:

You might want to look into using https://github.com/jj1bdx/airspy-fmradion instead of rtl_fm for stereo.

You can use https://github.com/windytan/wfm-tools together with rtl_fm to get stereo, though I prefer https://github.com/jj1bdx/airspy-fmradion
