[Abcde-users] need help with a gap of silence in a flac encoded file near the beginning of a piece

[Bodnar, Jason]

I think the only encoder the abcde uses for flac is the flac command line
encoder. I'm not familiar with the command line options for it but you can
read about them here:

https://xiph.org/flac/documentation_tools_flac.html

In your .abcde.conf file there is a FLACOPTS setting. I imagine you can add
any flac-specific options there.
