Hi ya all I would like to know about digital processing and how much the sound can be degraded by the use of DSP's.I read a scary artical on the net (i forget where and when ) and it was on about the more in the box processing you do the more the sound degrades. I'm using a vs1880 (roland)and it has alot of nice tricky bits and pieces(to many for me)but the article was saying using a few of them (quite a few I think)will make your end product lose definition and stereo seperation.I'm not useing much as I subscribe to the make it sound good at the mic school .But I'm concerned about compressing things in the mix and how far to go with verb and delay.I say less is more but can any one enlighten me further as to just what it will do to my tracks and does one highly processed track bring down the other tracks or is their sound quality independant of the rest . I know this is a very long winded question but I'm concerned with recording dead lines aproaching and me needing to get it right ????????
p.s. I dont want to go out of my box once Im in there(less a/d conversions)as I will endevour to make all the sounds good to start with(and please tell me if I'm making any sense).
 
Greeting rock,
Here is a link to a site that covers the mathmatic reasoning to what is going on.

Even though the article is about dithering, the process that your digital equipment does mathmatically is the same. Calculate, round off, recalculate, round off again...

Hope the link is useful.

Peace,

I just ordered the Yamaha AW2816 24 bit recorder with CD mixdown.

I hope I don't have to worry too much about using its 32 bit DSP?

I just read the article you suggested regarding dithering and mix down, etc.

The 2816 is a smaller brother of the 4416 by Yam. It's all done in the digital domain. So, what's your read on this new product from NAMM or NAAM? [can never remember the acronym.]

I was pretty disappointed when I saw the 4416 come out after I had spent all my money on the md8.
I just needed something for writing and composing that was affordable for a single income family of 4.
As far as I can see from the advertisements for the 2816 is that is a scaled back version of the 4416. Its has 28 channels instead of 44, and some of the functions have been relocated to other buttons. My only question would be whether or not the down conversion to CD uses truncation or re-dithering. The only reason I havent pursued giving up the md8 is that I like its analog mixing section, call it a fetish for being able to turn an EQ knob, I like being able to add a little verb without navigating 14 levels of software submenus on a screen a little larger than a pocket bible. More than likely Ill either get an ADAT or a Mackie HD24 with a console for driving it when the time and money comes in on that ship...

Peace,

According to the documentation at Yamaha, the aw4416 and aw2816 both truncate the 8 LSB during the down conversion to CD mastering function. Might wanna try a 24 bit sound card on a PC with something like T-Racks Mastering suite for re-dithering. If its going to truncate 8 LSB, why put such an
emphasis on the built in CD burner, other than for data back-up that is.

Peace,

That is scary!!! It don't even dither internally when burning a disk? Are you sure? That would be a VERY big overlook on Yamaha's part...:(

But they are very good at overlooking things! Better then at making any good sounding consoles - ehhhhhhhh I can't really say that, they've never made a good sounding console
 
Im pretty sure it truncates. Go to Yamaha.com, then after finding the ae4416 product page, open the PDF file for the users manual, it says it plain and clear about dropping the lower 8 bits. The article on dithering at digido warned that alot of the new fangled all in one DAW's didn't have a proper vehicle for down converting for burning CD-R's. The good new is I suppose is you can still get software and use one of the many different types of digital outs to a PC with some decent programs that dither.


Peace,

Good ol' Yamaha....

I am glad to not be mixing on the O2R anymore....:) That was a very low point in audio for me...LOL....
