How can I dither samples to 12 bit for EMAX?

2012-02-10 by zrennaya

Hello to all,

I'm trying to convert my WAV files for the Emax but keep running into the same issue. I have a mac running Logic which would allow me to bounce either 8 bit or 16 bit wav but not 12 bit. The Waves L1 plugin does 12 bit quantize with dither and noise shaping but it's useless, since I can only bounce the results in either 8 or 16 bits. The problem with this is that the 8 bit renders are way too lo-fi and the 16 bit ones will automatically reduce with no dithering in EMXP when I transfer them to EM1 floppys on my PC and the no-dither artifacts are audible again. This is very audible in percussive samples. Simply recording them through the Emax input won't help either..

 So I read it on a site about s900 samplers using 12 bit samples that mixing white noise into the audio at very low levels can actually do the same as dithering (don't quite understand why), tried that, same results except I had slightly noisier samples then :) 

I'm starting to wonder if Emax uses 12 bit samples at all. It' a little confusing that it it uses 12 bit audio "stored" in 8 bits, or as I read somewhere else, it uses 8 bit samples with 12 bit converters?! 

If 8 bit is the case, how come I cannot convert premium quality samples, using great quality dithering and noise shaping to 8 bit and still not get the cleanness of the factory Emax samples? Or if it's 12 bit, how can I render my samples to 12 bit and not let EMXP mess up my 16 bit samples? I've tried some of the Sound Designer installs available here, but couldn't get them to work on either the mac classic emulator for windows, or emulators for OSX. It seems like I must have been a programmer to be able to get them running so I gave up. Does anyone know of alternatives?

Thank you for your attention!
