Listen to HD radio with a $30 RTL SDR dongle
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.

(Unpopular?) opinion: KEXP’s John Richards is annoying AF
One key library that makes it possible is this one: https://github.com/ina-foss/inaSpeechSegmenter

ytmdl Web - A webapp that lets you download music by getting the audio from YouTube and metadata from various sources like Itunes, Last.FM, Gaana and others. v2 released with lots of fixes.
After looking for a few options, I came across inaSpeechSegmenter. It is a speech segmenter and if you pass it an audio file, it returns the time segments of noises and music.

Listen to HD radio with a $30 RTL SDR dongle
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?

I get good NOAA images with my DIPole. Should meteor look any better. Here are pictures of NOAA and METEOR. What is with the black and blue lines?
Here is the pic of the software setup. I have also used this on my computer using vmware and https://github.com/jekhokie/raspberry-noaa-v2. It handles all of the conversions and scheduling. I just had to play around to get it to setup on a non raspberry device. I included in the ticking system there how I did that.

using Raspberry-NOAA-V2 the METEOR-M 2 (like bellow) images are coming out fairly decent, but all the NOAA images aren't really working. why could this be?
I'm using raspberry-NOAA-v2 to automate the whole process, so yes I think it does do it via the command line.

Need help troubleshooting NOAA receives
I'm using raspberrypi-noaa-v2 to schedule and run NOAA and Meteor receives. I've got a brand new rtl-sdr-branded receiver and a bias-tee powered LNA, and am using the v-dipole antenna configured as instructed. My runs never show more than apparently random noise overlayed on the map. Can somebody help out a newbie to NOAA reception?

Bad Signal? I get no picture this is the audio and picture.
I have been using https://github.com/jekhokie/raspberry-noaa-v2 and i get the same kind of pictures. On this one i used SDR Console. It handles all the connection info and frequency/dopplar.

Christmas gift(s) for hubby who always wants to “make something”?
Buy that, introduce him to /r/amateursatellites, and have him use this (plus his existing raspberry pi) so he can receive weather pictures directly from passing satellites! I and others on that subreddit would be happy to help if he needs it.
