GNOME Gingerblue 2.0.1 is Free Recording Software for GNOME.
In the 2.0.1 release I have added support for XSPF 1.0 from Xiph.org.
If you launch the software, a immediate recording is stored into the
$HOME/Music folder along with the playlist in $HOME/Music/GNOME.xspf
You can download the source code from download.gnome.org/sources/gingerblue/2.0/gingerblue-2.0.1.tar.xz for the software and read more about the free playlist standard at www.xspf.org.
Distribution packages are available from
Fedora Core 34
