Stereo or Joint Stereo for mp3 320 CBR using foobar2000 and LAME 3.99. Options

[AlexanderMKD]

Hi all, im new here and im new to converting and decoding so i have one question...

I was wondering which is better for mp3 320 CBR, Stereo or Joint Stereo?

Im using foobar 2000 v1.1.10 and LAME 3.99.3 (stable release) for converting .flac or .waw to mp3 320 cbr, mostly i download a remastered flac discographys from rock and metal bands and convert them into mp3 320.

Also i like to ask for a explanation of a few options in foobar2000?

- Encoder: i use mp3 320 CBR, than i go to custom, choose lame for encoder and there is one more option... Bit Depht Control, in Format is: it haves option lossy and option losseless (or hybrid)... which one to choose? Highest BPS mode suported i have to default, on 24.

also i like to ask for explanation for these options in Processing circled in red?



Can Mono be converted to Stereo?


Thanks

Is really Stereo Lossy and Joint Stereo Losseless?

Stereo and joint-stereo are mathematically equivalent. We call joint-stereo "lossless" only to indicate this relationship and hence ease fear. It does not mean that one is lossy and the other is lossless.

why Force Stereo and not just Stereo whats the difference?

The other option is forced joint-stereo, not forced stereo. This forces all frames to be mid-side, while regular joint-stereo can use either mid-side frames or left-right frames, depending on which is more efficient.
