Can it be that this station uses parametric stereo?
No, as in such a case DABlin indicates "HE-AAC v2" and "Stereo".
No, this is mono.
OK then, it seems to be a bug.
Wow, your ETI file has a lot of frame count discontinuities! I think I'll generate an ETI with all combinations to test.
I see, I will check with another one
I've generated a mux with a few programmes: MP2 mono, MP2 stereo, AAC-LC mono, AAC with SBR mono, AAC-LC stereo, AAC with SBR stereo and AAC with PS.
dablin indication is correct.
welle-cli
with -Dw 7979
shows this:
The entry for AAC-LC stereo is wrong, it shows one channel. I'll see now what welle-io prints.
welle-io does the same error, except it doesn't show the AAC mode (LC, SBR or PS). I'll fix the AAC stereo LC case.
Fixed in 0cac18f
And I discovered that welle-cli
cannot handle mono streams at all :-/ Another thing to debug...
@andimik please open the issue again if you still have a problem with the signalling of mono/stereo with your programme!
Merci :-)
welle-cli mono decoding is now also fixed.
Makes it sense to print the AAC mode in welle-io in expert mode as well?
I believe it makes sense. This idea is tracked in https://github.com/AlbrechtL/welle.io/projects/1#card-9663493 already.
You are right. I added this issue to the card.
In Slovenija, some stations use 32 kHz 24 kBit mono, but it is shown as stereo.
Tested with b68d488 .

Dablin shows mono (and I know it as well)
