Some days ago i released an updated version of my MHWaveEdit port (now in sync with the original author
at version 1.4.23).
In this release i changed params to enable the program to start in a more large window and made Pandora params default at start so no need to change much (but you still need to enable the mic on XFCE mixer panel).
I have tested it recording for more than 60 min and didn’t crashed.
As usual the download is at Pandora repo
