Welle.io DAB/DAB+ Decoder Version 2 Released

Welle.io is a Windows/Linux/MacOS/Android/Raspberry Pi compatible DAB and DAB+ broadcast radio decoder which supports RTL-SDR dongles, as well as the Airspy and any dongle supported by SoapySDR. It is a touch screen friendly software which is excellent for use on tablets, phones and perhaps on vehicle radio touch screens.

Thank you to Albrecht Lohofener, the author of welle.io for writing in and sharing his news about the release on welle.io version 2.

welle.io 2.0 Beta 1 released

I’m happy to announce the version welle.io 2.0 Beta 1. Since the first rtl-sdr.com post roughly two years ago (Mar 2017) welle.io became the leading open source DAB/DAB+ SDR. Many people are using welle.io in their daily life and gave a lot of feedback.

With all this feedback we started developing the version 2.0. Apparently, the biggest change is the complete redesign of the user interface (GUI). It changed from a dark design to a bright design and handles easily different screen resolutions and orientations.

Many users asked for a favorite list, automatic playing of last station and a mute button. Now these features are ready to test with the 2.0 Beta 1!

Another new feature is the settings menu where users can set the hardware receiver with all the necessary settings. This is more user friendly than the command line parameters.

For people with a deep technical interest we improved the expert mode a lot. In addition to the spectrum users can also view the impulse response, null symbol and constellation diagram, even at the same time! An experimental I/Q RAW file recorder as well as a debug output window is available for systems without a text console.

In the back-end we improved the multi-path behavior and started a source code refactoring to allow the code to be easily maintained. Great thanks to the people from the Opendigitalradio association (http://www.opendigitalradio.org/) which are actively contributing to this project.

Now it is possible to build a complete DAB/DAB+ system (transmitter and receiver) with open source!

As a result from this collaboration welle-cli is available. The main use case is to monitor DAB/DAB+ transmitters networks over the internet. Thus it has a HTTP API and includes a basic Web page which shows the features.

Everyone is invited to test the new version and to report issues. For reports we recommend to open an issue at the welle.io Github page (https://github.com/AlbrechtL/welle.io/issues).

We are also looking for people who would like to contribute to welle.io (translations, web page, documentation and development).

We wish everyone a happy New Year!

“Imitation is the sincerest form of flattery” (Charles Caleb Colton)
Yes, I feel flattered: Look at the constellation diagram (not working properly btw), and compare with qirx (www.softsyst.com/qirx). Looks VERY similar.

I am not expert but is a constellation diagram something that can be considered copyrighted?
Why not apply for a patent then?
I can immagine what the first creator of SDR thought when he saw others using the waterfall…

Tested on Windows, and I was disappointed. Really, there could be ExtIo input, so anyone could use Welle.


Ubuntu 16.04 moans about Glib deps missing, can be solved:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

You can check if you get GLIBCXX desired version like this:

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

Ubuntu 18.04 no problems.
