Currently the version of FLAC in use is 1.2. Is it possible or even desireable to upgrade to 1.3.3? If so, what is the procedure for upgrading?
I think you're in the wrong forum thread ("Uploads" isn't about Upgrades), but Foobar was updated to FLAC 1.3.3 with version 1.5 (see Change Log here: https://www.foobar2000.org/changelog (https://www.foobar2000.org/changelog))
As far as encoding, the latest Foobar Free Encoder Pack from Case also uses FLAC 1.3.3; so, if you have that and Foobar 1.5+, you are already upgraded.
Thanks! I see where I was going wrong. If you edit the FLAC information it tells you that "FLAC Encoder 1.2.0 or newer is required> I assumed that meant that 1.2.0 was in use. A little confusing! After checking, I have the latest version and had installed the encoder pack also! Much appreciated!
