Converting FLAC to MP3 on Ubuntu 8.10

By the way, for some reason, when I right-click on the track, go to Properties>Audio...it only shows it as 318kbps. Not a full 320kbps. Not like it's a big deal or anything, it's still a great bitrate. I just don't see why it would show it as a 318. The commandline previously suggested is actually based on VBR (the --vbr-new switch chooses the improved and faster VBR psymodel), but it is forced to a minimum bitrate of 320 kbps (which is also the maximum). The only exception allowed by that commandline is that complete frames of total digital silence (e.g. at start or end of track) can be encoded using 32 kbps frames. I'm not sure which VBR profile would be used, but it might be the default of -V 4, if an alternative like -V 0 isn't specified! One of the tabs in Foobar2000's Properties dialog (right click on track) might tell you the VBR profile that was actually used when none was specified. You might also try mp3repacker or winmp3repacker to see how much blank padding (unused space) can be losslessly removed from the file. If you want true Constant Bit Rate (CBR) even for digital silence (e.g. because you have a non-compliant decoder that dislikes VBR) the commandline parameters for 320 kbps CBR (also known as --preset cbr 320 or as --preset-insane or --alt-preset insane or most simply -b 320 )would be: Parameters: -S --noreplaygain -b 320 - %d If you had another parameter that turns on VBR or ABR mode, such as --vbr-new, you can supposedly enforce CBR mode by using --cbr in conjunction with -b 320, though I'm not absolutely sure that CBR wins, nor do I really care as we ought to use the correct commandline rather than a conflicting one for normal encoding unless testing something.
