Use a for-loop:
FOR %A IN (*.flac) DO @ffmpeg -i %A -map_channel 0.0.0 %~nAleft%~xA
-map_channel 0.0.1 %~nAright%~xA
This will process all flac-files sorted by filename. If you want to process
them sorted by date for instance, then you can do:
FOR /F "delims=" %A IN ('DIR /B /O:D *.flac') DO @ffmpeg -i %A -map_channel
0.0.0 %~nAleft%~xA -map_channel 0.0.1 %~nAright%~xA
