3 useful websites to obtain details on url stream addresses:
1) FM STREAM: Site address is "
https://fmstream.org" Over 80,000 listed streams... click on a station to play within a browser. Especially useful as it lists all of the direct stream addresses for stations that have multiple streaming options (high bitrate, low bitrate, mp3, aac, etc)... and most stations do
2) RADIO BROWSER: Site address is "
https://www.radio-browser.info" Very good database that is maintained by users
3) RADIO LOCATOR: Site address is "
https://radio-locator.com" Been around for decades listing AM and FM radio station information (power, daytime & nighttime signal coverage maps, etc). They also list url stream address information
Personally, I much prefer listening to radio streams on my devices (including WiiM) by using the custom stream address that I personally input myself instead of relying on an app or browser to blindly choose a stream for me. That way I know exactly what I am getting and can ensure that I get the highest quality sound available. I find that accessing stations on TuneIn, Audacy, vTuner etc "blindly" connects me to a station, and oftentimes does not choose the best available stream. For example, TuneIn oftentimes defaults to a 128kbps mp3 stream for a given station when that same station offers much higher quality (192kbps, 320kbps, aac+, aacHE, flac, etc). I am hopeful that the WiiM app will someday allow the user to select from multiple streams for any given station when choices are available... that feature was mentioned in the development roadmap a long time ago.
