JvanKatwijk commented 7 years ago

Yes, file is written

OK

It would be really helpful if you can send a link to a file where there is a noticeable difference in the behaviour using the januari version vs the recent version of the eti-frontend. Running here - with an airspy as input device - does not show mch difference (note that the january version contains the error with handling protection level 4, and incomplete versions of pad handling, so it need some updating before promoting it to the "current" version).

Again, I am not very satisfied with the eti-frontend as it is, it needs a redesign on its input. If we would accept that running the frontend on the raspberry 2 is not an option, internal operation could be simplified a lot

I just had 2.5 hours music using the eti-commandline + eti-backend combination working fine. I suggest further development of the commandline handler - i.e. adding file input, better defining the parameters - and withdrawing the Qt based version. The latter needs too much work before all issues

I cannot test eti-cmdline because it seems not to be configured for file input.

What happens when you pipe eti-frontend to eti-backend?

eti-frontend -O - | eti-backend -s -

Newer versions (later than January) have lots of dropouts, but it could be just a break between the audio frames. Because when I record it through the "audio" button, the sound is ok and the audio is playing normally.

See https://github.com/JvanKatwijk/qt-dab/issues/22

The soundcard output is indeed that

I would suggest to go back to this January version and fix the 4A issue, the file extension issue, and the ETI file handling issue for Windows.

Thanks for your PM (I also have replied personally as well, ;-) ).

The eti-cmdline now looks pretty good and is very simple to install (not compared to that one on github).

My aim is just to record DAB muxes wherever I am (on vacation, etc) and replay them later and to minimize filesizes (-> eti is the best way).

JvanKatwijk commented 7 years ago

I assume(d) your preference was to record 8 bit streams. I intend to add the 16 bit sdr files as well (and add some testing stuff)

One of the advantages of the command line version is that all parameters are fixed at program startup time. If you have special issues on this eti-cmdline thing, pls let me know

Closed as not more necessary due to the new eti-cmdline implementations
