Is higher better or lower?? Most are 128 but some are quite a bit higher and others are lower. Whats the best audio quality for burning to CD's, higher or lower??
Higher is better. 128kbs is usually considered to be the minimum to be CD quality for MP3s, tho' personally I don't think anything under 192k sounds as good as a CD.
There's no best per se -- well, actually the best would be a lossless compression rip to a .wav file or similar format. The penalty, of course, is file size. Personally, I use a variable bit rate setting with the min at 160k and the max at 320k.
I'm surprised you're seeing a lot of 128kbps out there. Pretty much everyone agrees that's not high enough to sound good. 192kbps is a good minimum, preferably VBR.
See my reply to the same thread you posted in the Audio/Video Sources forum. FYI, it's generally frowned upon the post the same question in multiple forums here.
