hi m new here
i have a hifi system marantz mcr 502 with speakers
on whom i listen to music via usb stick(mp3 320kbps cbr)
all of my music is in flac
i convert the music from flac to mp3 320kbps cbr with foobar2000
i wanted to ask is in my case better to convert the music to mp3 320 kbps cbr or 320kbps vbr?
what s the difference?
if its better to convert it to mp3 320 vbr, can you tell me a few softwares which are good for converting in mp3 320 vbr
is it possible that if i convert an album in mp3 320kbps vbr, that i will get a smaller bitrate than 320kbps??
that s why i thoguht its better to have 320 kbps cbr because thats always 320kbps the same, i thought that if i convert it in vbr 320kbps ,that i could get than a smaller bitrate like 256kbps or ....
and also i don t have in the foobar converting options(converter setup) the ability to convert my music in mp3 320kbps vbr
i just can download the music in mp3 320 cbr

Assuming “320kbps vbr” (which doesn’t exist) means -V0, then yes; that’s the point! Because…

…this saves bits from being wasted on regions of audio that are not complex enough to demand 320 kbps; it may also enable regions that demand more than 320 kbps to receive the extra bits via the bit reservoir. The overall quality of -V0 is likely to be on a par with or better than -b320.

Anyway, both settings might be more than you need; the way to check this is to, as suggested, perform ABX tests on these and lower settings across a representative set of tracks from your library.

There have been several past discussions on the two settings, on which LAME settings are generally transparent, on ABXing, etc.; you may be able to get more information by searching for those (using the built-in Google bar) than by waiting for users who feel like retreading the same ground again.
