As already mentinend in this thread some fanboy over at the offical Pioneer forums is making claims that VBR sucks (here and here) in that it needs more processing power compared to CBR and for various other reasons.
I would like to have a well written rebuttal of that statment based on facts so Pioneer might reconsider putting VBR support into their upcoming DJ equipment. I've ripped all my 1000+ CDs to VBR and I wouldn't want to reencode them just because Pioneer doesn't get it right. Thanks! |

QUOTE (Canar @ Oct 21 2008, 13:16)  However, castanets.wav exists at http://ccrma-www.stanford.edu/~bosse/ apparently. Actually, castanets.wav is listed there but when I try to download it I get a 345 byte file. Definitely NOT the proper file  .@halb27: Thanks for the link. I'll search out those other tracks; I haven't heard them personally but that's alright. I'm going to search my collection for some other "problem tracks" as well and see what I can come up with. I'm planning a rather epic post over at the Pioneer forums with my own sets of data, samples, and trials to try to clear up any FUD that has been spread, as well as to (hopefully) kick Pioneer's ass a little bit in terms of fixing their VBR support (if that's what the data shows, which I'm sure it will). Once it's posted I'll link to it here. This may be a stupid question, but since it's relevant I'll ask it anyway: if I zip (or rar) the samples purely for the purposes of having a single file to download for the members (which I'm sure will include whatever mild amount of compression WinRAR can achieve), will this affect the quality of the unzipped/rared samples? I assume no, because encoding something like a binary would necessitate lossless compression. However, I just want to make sure I don't shoot myself in the foot before I start. Thanks. -r- |

Zipping/unzipping (resp. using WinRAR) is a lossless process no matter what contents is zipped.
