About 80% are my own CD collection. The rest is MP3 mixes by different DJs, friends, my own.MP3gain can tell you if the file has an issue (it won't be able to process it).
You're mixing things in a way that it piles up according to your expectations and without any kind of sense. "Eyes blur, the ears (...) less" has nothing to do with VBR. Why do you think that?
I was (possibly falsely) making the assumption that an audio CD would already be at least partially buffered to memory by such a player to allow tricks in real-time (you can't physically play a CD backwards... can you?) and that the MP3 data would be using the same buffer in the same way once decoded to an equivalent linear digital format and still using the same "trick" hardware/DSPs.
The encoder is "starving" bits in complex parts and "wastes" bits in easy to encode parts. VBR simply aims to maintain a constant level of quality throughout the encoding.
PS Apologies to DJRyanJ for the dig earlier. I got the impression that you weren't prepared to listen to logic or partake in reasoned debate. How wrong I was
I'd say that's true of VBR encoder settings that use the full range vs. CBR settings below 320kbps; it's NOT true of 320kbps, which is the max anyway and is what I use. While at 320 it might be "wasting bits" on the uncomplex parts, the same could be argued for an uncompressed file - do we REALLY need all those bits to describe some minutia of the sound that we probably can't distinguish anyway? Isn't the sonic quality presented by MP3 "good enough" for "most people"? I'm sure you'd say no, but then we're right back to the same argument.
320kbps is a "safe bet" but you don't need that high of a bitrate when encoding audio even for DJ purposes. The environments where DJs often play are not really optimal for music.
So go ahead and argue that 320kbps is a safe bet (or that you need it as your ABX tests have shown that). However, I wouldn't argue that that uncompressed audio uses more bits that needed and make that look bad and then come back saying that 320kbps uses more bits than needed and that is alright.
What I DO argue however is that while DJ environments are never (or rarely optimal), I don't want to be the limiting factor, so I play the highest-quality music I can given the tools I use.
Generally, you'll get no argument from me and I said as much in my first post. What I DO argue however is that while DJ environments are never (or rarely optimal), I don't want to be the limiting factor, so I play the highest-quality music I can given the tools I use.
I would never say such a thing! LOL and if I did, then that's not what I meant. I was arguing that SOME PEOPLE might say that uncompressed is pointless as it uses more bits for the same thing that people can't hear anyway. I would rather use uncompressed; but the realities of what I do make that impossible (for now).-r-
[off-topic]Happy 1000th post! [/off-topic]
On that basis, if you found out that that you couldn't tell the difference between a CD quality source and, say, the ~128Kbps LAME VBR in our listening tests, would you then reconsider your need for 320Kbps CBR?
Even if you use lower bitrate music (128kbps-160kbps), you won't be the limiting factor. There are far too many factors that degrade the perceived sound quality of music let alone in a club/dance hall/whatever. Also don't forget that you are playing music for an audience where the majority of people are fine with 128kbps WMA/AAC music from legal online stores. Just know that the quality of music that the DJ uses if often the very last limiting factor amongst thousands of other factors.
The use of uncompressed audio simply is not needed in a day where we have lossless codecs and high performing lossy codecs that can achieve transparency at such low bitrates (128kbps). ... I think that will help you further understand what we are trying to say.
I'm not ready to do that just yet, for a couple of reasons:1) I occasionally remix the tracks I use, and while I'm no pro remixer, I try to maintain quality where I can. When an uncompressed version is not available, I must use my MP3 copy, and in that respect having the highest possible original copy is best.2) I don't have a problem with the amount of space that a 320kbps CBR takes vs. a VBR. I've accepted the amount of space that a 320kbps CBR takes and I'm OK with it; if we can all agree that the point of MP3 is to save space, then likely everyone has a different level that they're willing to accept in terms of saved space. Mine is currently at 320kbps.3) I don't totally trust my ears. That sounds ridiculous given the topic at hand, but just because I can't tell the difference doesn't mean someone else can't (or won't be able to in the future - my music collection is also designed to last a long time).
Well, I'm sorry but ...
I can't work out whether this is in response to my post.
If even a single frame uses 320 kbps then the entire file must, after repacking.
MULTI READSupports playback of CD-R and CD-RW discs. (Some discs may not replay properly, however, due to certain special characteristics of some discs and recorders, as well as due to dirty or damaged discs.)
a) a full-fledged MP3 player has got to be able to work with VBR or be renamed
Since Pulse as a regular seemed to be leading the discussion on VBR over there with opinions rather than facts...
Pulse should stick to what he knows.
Unfortunately, with mods like Pulse in that forum, I don't hold out much hope for you changing anyone's opinion...
I suggest you go and take a look at the current discussion. Pulse has admitted that he has much to learn and is willing.
Lossless formats such as FLAC and Apple Lossless are able to shave off 10MB or more from the file size (when compared to uncompressed WAV) while retaining track tag information and still being bit-for-bit identical.

That's not what they were truly designed for, it's just an added feature.
The ProDJ CD-Deck combines key elements of the Pioneer CDJ-Players with a host of brandnew functions like a full-fledged MP3-Player, Hot Loop, Beat Loop und our unique Loop Cutter...
Plays MP3s* MPEG-1: Supports Audio Layer-3 sampling frequency 32kHz, 44.1 kHz, 48 kHz, Bitrate 32 Kbps ~ 320 Kbps.
However, castanets.wav exists at http://ccrma-www.stanford.edu/~bosse/ apparently.
It refers to the LAME problem samples page for castanets.wav, which no longer exists.
