so, the flow is: Once the file is created a script, I called it dab-skeleton.bash, parses the channel list and When one of these "webradios" is played and opens the stream, rtsp-simple-server starts "dabstart.bash" with the appropriate parameters. As the music is stopped the rtsp server sees the connection is closed and stops the dab tuner. I haven't found a way to stream the raw pcm or the same pcm in wav or other lossless formats. about the advantages over internet radio, first of all it does not need internet, so if you have your sound system somewhere without connection you can listen the radio anyways, second you don't have to add the services one by one (in Rome for example there are around 130 DAB radio channels available) and, last but not least, no other player has it as far as I know. |

Forgot to add, these are the packages needed to compile and run the dab tools: probably base-devel and cmake are not needed if the binaries are provided |

Hi @rern , So I spent a little time more and modified cmd.sh, status.sh and status-radio.sh to update the gui with the info transmitted by the broadcaster, plus I added creating the coverart files to dab-skeleton.bash and used subfolder DAB for the DAB radio files. The archive attached has the new versions of the files, it seems to work for me. |

Hi @rern I also tried to pack all the thing in an addon format so I cloned your repos rAudio-1 and rAudio-addons and modded stuff here and there. I changed the release number and the "sourcecode" and "installurl" path to point to my repo. |

Hi @rern , I've put everything in my forks of your repos rAudio-1 and rAudio-addons. Now in the library update pop-up there should be a new element to scan the DAB radio channels, as it finishes (no progress indicator, sorry) it will add the radio stations in subdirectory DAB. There are three things I could not figure out: |

Hi @rern , 2 - in dab-skeleton.sh dab-scanner-rtlsdr can not be called without any parameter, a workaround is to call it with an initial channel to scan: 3 - in dab-skeleton.sh, line 41 must start with two blanks or the resulting yaml syntax will be wrong, also the following lines have to start with four blanks and not with a tab: 4 - the file /srv/http/data/shm/radio is not created and the radio service is not started, the journal log shows this when a dab radio is started: |

@rern about point 4 the problems I think are: in status-radio.sh line 48 is missing the extension in filename, should be again in status-radio.sh line 75 Last thing about status-radio.sh, the online check at line 3 should not be executed as if the radio is DAB then being online is not necessary to update the metadata. The check is done at lines 43-45 With these fixes everything seems to work as expected |

Hi @rern , Apart from this there are other two problems: 1 - there is something wrong with the gcc-libs. however the gcc-libs result installed: doing "pacman -S gcc-libs" reinstalls them and afterwards the info on the package are exactly the same but libasan is while in the original image is: and libstdc++ after update: while in the original image: ) and two dab tools start ok: 2 - Another thing I had overseen before, you added a "systemctl restart rtsp-simple-server" at line 48 in dab-skeleton.sh The rtsp server reloads the configuration automatically when it senses that the file has been changed, so it not necessary to restart it. systemctl enable --now rtsp-simple-server then forget about it. |

Hi @rern 1 - the label format is not standard and does not always report the album/song title, often it displays messages about next program, or other stuff. Not all the radios are broadcasting music all the time 2 - I had not found a way to inject a changing label in the ffmpeg stream, and I'm not sure which metadata can be passed on by rtsp-simple-server (see bluenviron/mediamtx#979 ) 3 - one of the advantages of DAB radio is that does not require internet so is suitable for setups in i.e. a countryside home without connectivity, in such a situation the online search for the cover art would be impossible 4 - the standard behavior of the DAB radio players I've seen is to display the image and the label from the broadcaster For all these factors I decided to avoid spending too much time in finding a way to fetch the coverart online. Something that I thought was worth of some attention was instead trying to convince the ffmpeg developers to support the special DAB+ frame size, it's a request which is open since 10 years but for some reason has not received much attention. Having ffmpeg understand the AAC DAB+ format directly should avoid decoding it to PCM and reencoding it to a standard AAC, the dab command line tool could output the raw AAC frames and ffmpeg could only add the RTSP format encapsulation to pass the stream as is to the rtsp server |

Did some test, I think something happened to my antenna while I was out because it struggles to get the signal, however there are at least two problems in the scripts. In dab-scan.sh, which does not put the port number in the file name, change line 35 of the file with: then in dab-start.sh the order of the options for ffmpeg is wrong. Fix it by deleting lines 23-35 of the original file and replace them with: Let me know if this helps. |

I suppose that the executable that returns the buffer underrun is the "nostreamer" one. The DAB+ standard streams data in AAC format with a frame size which is not supported by ffmpeg, thus the program uses a different library to decode the flow internally and output PCM. However raw PCM is not a supported format for the rtsp protocol, thus I need to reencode the PCM stream to AAC with a supported frame size to be streamed by MPD which uses ffmpeg as codec. There is this bug open since a LOONG time on ffmpeg supporting this frame size directly would avoid a lot of CPU work, but the ffmpeg team does not seem to be interested. |

It looks that it's more of a reception problem that I have than a cpu load problem. |

The best thing to check whether it is a reception problem is to use a more powerful PC, connect the SDR dongle to it and check with a GUI DAB receiver the signal levels. |

@rern there are a couple of problems in the new DAB scripts. The dab-scan.sh does not add the port to the file name and in dab-start.sh you changed the order of ffmpeg options, but in ffmpeg the option order matters because the options before the input file specification are for the input file and these between the input file name and the output file name are for the output file. In this post you can find the corrections necessary to make it work, however it still seems to fail picking up the radio text and art, will check it better later |

@rern sorry, found one more issue. The ensemble name is not "sanitized" before being used to create a directory, so it failes to create the directory (and consequently all the files) for one of the ensembles in my area which is called If you change line 22 in dab-scan.sh this way it is better: The xargs at the end just trims the leading and trailing spaces. However, in my opinion, it is not worth the pain to create subdirectories for the ensembles. At least in my area they have not meaningful names and the providers can be quite "original" when they decide their names. |

There are two ‘general user’ programs which decode DAB+ - welle.io and guglielmo - the latter only available on Debian-based OS.
Also the ‘rtl-sdr ’ program sdrangel has a DAB+ decoder.
Does anyone else know how they do it (none are particularly cpu-lite)?

The standard executable has a thread that fills with silence the "holes" caused by data not incoming. If without this you get buffer underruns I'm afraid the cause is that the CPU can't elaborate the incoming data timely.

However raw PCM is not a supported format for the rtsp protocol, thus I need to reencode the PCM stream to AAC with a supported frame size to be streamed by MPD which uses ffmpeg as codec.
All this decoding/reencoding/decoding is done in real time and adds CPU load which is probably excessive for the rpi3 CPU.
There is this bug open since a LOONG time on ffmpeg
https://trac.ffmpeg.org/ticket/1407
supporting this frame size directly would avoid a lot of CPU work, but the ffmpeg team does not seem to be interested.

I tried to compile it and of the 4 threads created by the command, the one which uses the most CPU stays around 70% for the latest git version and around 40% for your version. The only downside I see that with your version there is no label and image but probably it is not so difficult to add them, at least for the label the callback seems to be already there. @rern your choice to include or not the "lite" version of the decoder for slower CPUs |

DIY (cheap!) Internal DAB Aerial
Nov 19th, 2010 at 5:23am
I've seen a lot of queries about this, it's often Googled, but I haven't seen this very simple -- and ridiculously cheap!-- DIY aerial design anywhere.
All you need for a much more efficient internal DAB aerial (much better than a 'T', dipole or existing external FM aerial) is two or three metres of standard 75 Ohm co-ax aerial cable, a few cms of insulation tape, wire strippers or a pair of scissors, and an 'F' or 'UHF/VHF' plug (whichever suits your tuner.)
Strip both outer insulation and the braided shield from 300mm/12ins of one end of the cable, just leaving the insulated inner core.
Now carefully strip the outer sheath from the next 230mm (9ins) of the cable, making sure the braid isn't broken. Wrap a little tape around where the shielding braid meets the stripped inner to stop it unravelling.
Now, at that point, where the cable is fully insulated, make a coil of two turns of the remaining fully sheathed cable. The diameter of the coil should be 50mm (2ins).
Secure the coil to stop it unwinding with insulation tape. (Or strips of gaffer tape, which is stronger. Or anything, as long as it isn't metallic.)
Attach the 'F' or UHF/VHF plug to the untouched, longest end. Tape a loop of string or whatever to the top thin end, so you can hang the finished aerial vertically from a nail or drawing pin in the wall as per aesthetic preference. One of mine dangles from a curtain rail behind a curtain, the other from a picture hook, so it's hidden by a picture.
Don't ruin it by letting the uninsulated braid touch anything metallic; and don't coil the long end of the cable!
Plug in to your tuner's DAB antenna socket. You will probably now receive all your 57 or whatever stations at a much higher signal level than using a dipole or 'T' aerial. And probably better than a pricey amplified set-top gizmo.
That's it.
The dimensions don't seem to be absolutely critical except for the top 300mm/12ins; the second stripped length can be up to 10mm longer (9.5ins), and the coil can be a few mm wider; it is a bit tricky to get those two exact anyway, especially with the stiffer 75 Ohm cable. The brown (heavy duty external) type is best, because the shielding braid is tighter woven, the insulation is easier to simply pull off it and it's less likely to unravel.
Don't use thin 75Ohm co-ax, because the braid often sticks to the insulating sleeve, making it very difficult to strip, and it has to be unbroken.
You can probably get away with a metre or three of cable between the coil and the tuner if need be, but the shorter the distance the better I think. I've never actually tried a run of more than a couple of metres, but the cable's cheap, so you can always experiment.
I use one with a Samsung
DAB mini-system and a TEAC 300DAB tuner, with good signal strength and no dropouts in two different rooms, even being on the first floor in London where an internal VHF aerial only works in a couple of positions. And it gives me a better signal than using my big 7-element VHF aerial on the roof 10m higher and aligned on the transmitter.
It may not work for everyone, because proximity to the transmitter is everything as far as digital is concerned, but for just the expense of a couple of quid, it's worth trying before either giving up on DAB or going to the expense and hassle of getting an external DAB aerial fitted.
(The design was given to me by Siemens Research in the UK, right at the beginning of DAB when I was reviewing the first experimental receivers -- via strung-together boxes, power supplies and software on a laptop!--for Hi-Fi News. It was the only way then of getting a signal when the only really effective aerial available was an old ITV H-type turned on its side. Which had long disappeared from my roof.)

On an other subject, would it be possible to not have the different ensembles displayed per folder but just one list
with all dab radio's (like in webradio) I find it kind of "annoying" to have to go out of a folder to then go into an other
folder just to change channel ;-) Maybe the folders can be added as an option just like in the webradio?

But it works really well enclosed (apart from the coil) in a 22.5 mm pvc pipe for sturdiness. Other diameters may work also.

So, I invested in a external dipole antenna, a whopping 17€ :-) and I got plenty of channels. Started one of them and played just fine without any interruptions. But hen I selected a channel from an ensemble from the other side of the (small) country, got tuned but then rAudio just hanged, couldn't do anything anymore so I had to cut power and start up again, but it wouldn't, SD card got messed up. So I had to redo everything from scratch, put the latest image 20220917 on it and scanned the DAB. @vale-max Could you please give me a hand to figure out what's wrong? |

hello @skycamel The "fprintf" version uses printf to output messages as the c++ method seems to mess up with buffers. Try the by copying them over the original /usr/bin/dab-rtlsdr-3 (make a backup copy of it first) and let me know which one works better. If nothing seems to solve I can try to build a version printing some info about the signal quality but I can't do it before monday. One last thing, I've noticed that if a station with a weak signal is played the dab decoder exits, moreless cleanly but the main problem does nor seem to be the decoder crashing. In such case MPD gets "confused" and even if the streamer closes the stream MPD keeps waiting, stops responding to mpc command and finally hangs the rAudio GUI. These are the same symptoms someone in other threads had with lagging internet radio streams. |

@luc - you could try a powered usb hub, but to ensure reliable operation you may need to isolate it from the pi with another unpowered hub.
So rtlsdr > powered usb > unpowered usb > RPi.
This will reduce the power drain pn the pi.

Yesterday I did some antenna work to increase reception and to somehow rule out bad reception as an issue.
I scanned and I got all available DAB+ channels in my area.
The issue remains when I start a channel it can take up to 2 minutes before I get sound, in the GUI I can see the channel, service and freq
displayed once I press play, but then it takes a long time for sound to be produced.
I fear it is the (lack of) cpu power that is the problem. I deduct this from the fact that when I'm in the GUI on my laptop or my
phone I start getting interruptions, probably because it also takes up cpu power.
I hope there might be a way to decrease the needed cpu power to use DAB, I'm not really planning to upgrade
my rpi3B+ to a rpi4.
In any case @vale-max thanks so much for your effort, it's certainly an important addon to this already wonderful product.
Cheers,

And (of course) as soon as I had sent that mail, now they all open! But the search box is still not there.

No, we’re back to not being able to open multiplexes. Though one did open, it is now refusing to do so. As are all the others.
And the search box sometimes appears, and sometimes not.

If you're looking for the DabEnsemble folders you will find them in the "/ " (see #104) |

Great progress!
I would love to try this but may be unable for a couple of weeks. Will see.
In the meantime is there a way to implement sorting channels alphabetically in a single list instead of in folders, and is there a way to implement a favourites list?

Success! That's working fine with these commands. I had one slight interruption but I'm sure that was the reception.
Does that mean it will only work on rpi4 :-( ?

I would like that too, a single alphabetically sorted list. Edit: Actually, copy the services in /srv/http/data/dab without using subfolder |

Hello @rern ,
I have implemented in my rAudio on raspi4 a set of modification to have DAB radio available on rAudio.
Using only open source tools ( https://github.com/JvanKatwijk/dab-cmdline and https://github.com/aler9/rtsp-simple-server ), an RTL-SDR inexpensive USB stick and a couple of scripts I built a set of webradio files that once played trigger the start of the DAB subsystem.
It all works pretty well without modifying anything of the standard rAudio files, however it would be nice if the web interface could display the "slide" sent by the broadcaster and the Dynamic Label (a kind of RDS, can be used to inform about the song played but it is used for any kind of text message). Currently the DAB client writes the slide in a 320x240 jpg file and the Dynamic label in a text file of few chars, but nothing processes these files yet.
I had a look at how the status.sh and status-radio.sh update the metadata for the known webradios and it is not terribly straightforward, so to add the possibility to read and display the label and the slide I'd have to do quite a bit of reverse engineering of how the flow goes.
Are you interested to add this feature to rAudio?
If you do I can give all the details about what I did for you to integrate it with the GUI.
Let me know,
Valerio
