Poor u8 support

[andimik]

The actual version ODR-DabMod version v2.6.0-69 ( g029e9c7 ) has a very bad u8 support. Even with very sensitive AbracaDABra I get only 4.9 dB and poor audio.

Then I went back to a former installation, ODR-DabMod version v2.6.0-1 (g12f6daf), 12f6daf

Much better, 31 dB

It's both times the same command.

$ cat ./foo.eti | odr-dabmod /dev/stdin -f /tmp/foo.raw -F u8

Interesting observation? Are you able to narrow it down to the commit that changes this behaviour?

[andimik]

Yes, but only when I find some time. In the meantime I will use the old one.

But this is the difference (I even did not know it's so easy to compare two commits):

https://github.com/opendigitalradio/ODR-DabMod/compare/029e9c7..12f6daf#diff-4634e877086bf0dad2d6bede99eb945ff1b0dd381662d8dda7b5afb56ee99dcb

check formatconverter.cpp and the for and else , but I have no idea what it means.

Thanks for notifying me about this, and for your analysis. Can you try latest 'next' ?

[andimik]

Yes, that 03bf901 fixed the issue :-)
