    Re: Cransong Dither cd

    It\'s a nice fantasy, and a good way to separate you from $30. But it\'s a CD of hiss, perhaps expensively shaped hiss, but all the same...

    ssssssssssssssssssssssssssssssssssssssssssssssssss ssssssssssssssssssssssssssssssssssssssssssssssssss ssssssssssssssssssssss-that will be $30 pleasssssssssssssssssssssssssssssssssse.

    The problem is that you\'re inserting shaped dither noise at a place in the chain where you won\'t get its benefit. Your mix engine will take that \"dither track,\" mix it with everything else, and re-quantize it.

    The only reason you use dither in the first place is to cover quantizing noise (jaggies) with more pleasant noise. If everything stayed 32-bit from the mix engine forward, or even 24-bit, we\'d never use it at all.

    But by following the directions for this CD, you\'re taking your nice clean expensive Cranesong-approved noise you just bought, gakking it all up again by requantizing it (therefore giving its formerly smoothing effect the same \"jaggies\" it\'s supposed to be masking), and now you will once again \"shape\" that noise.

    Noise shaping takes the dither noise that\'s been added (to cover quantizing jaggies), and EQs it out into the nether-regions of hearing. It\'s \"there,\" it fills acoustic space, so it\'s perceived as taking the same edge off quantization error, but in frequencies where your ear doesn\'t respond as well--at a certain level. In fact, all the pro-grade limiter/dither/shaper plugins boast highly optimized noise shaping...the holy grail being the most noise you can add without the human ear really perceiving it, so that the quantizing noise (which is as extreme in its harshness as the shaped noise in its smoothness) gets masked as much as possible.

    Whew. Everybody with me?

    Sorry to lay out so much in response to such a seemingly simple thing, but people don\'t generally understand the whole quantize (reduce bit depth), dither (add noise to cover the \"jaggies\"), and noise shaping (EQ the dither noise to less sensitive frequency ranges). And it\'s necessary for someone to fully comprehend that process in order to realize this product is, in fact, high-class snake oil. It may represent a high quality dither and noise shaping \"hiss track,\" and may fool your ears in the same way that ANY pleasing noise sneaked in behind a track will impart a fake \"warmth.\" But I\'d say skip it and enjoy a nice bottle of wine instead.
