I used the sf2convert tool and converted the SF2 soundfont to SF3 and SF4
and compared the file sizes to the original SF2 file.
Only for the SF3 file I was able to check the sound quality with our
software which uses the libfluidsynth library. The sound quality of the SF4
file I did not check. Sorry, in case my comment was misleading. 

Best regards,

Reinhold

Very interesting, thanks for explaining your use-case. How did you
test the converted SF4 files? Did you patch fluidsynth to allow FLAC
decompression? Or did you use a different synth?

It is not about removing ogg support in favour of flac, but rather
adding flac as an additional compression choice next to ogg vorbis. So
don't worry, SF3 is here to stay.

Cheers
Marcus
