Dither

Postby Perfect Record » Tue Aug 25, 2009 19:18

Yup, I know this belongs in the suggestion board, and I did post it there, but didn't see any response.

I'd like to see Pyramix offer MBit dither from Izotope.

I'm exporting CD mixes to my Mac, where I have a utility that has MBit, then re-importing back onto Pyramix.

Anyone else had experience with this very nice dither?

Yeah it's great. If you happen to have the izotope ozone plugin (which is great btw) - you can just slap that on the mix bus and add the dither within pyramix that way. Obviously it would be ideal for it to be an option in pyramix, but.... this works :)

The only thing is the mixdown is very slow with version 4 of Ozone, at least on my mass-core system. It's somewhat faster with version 3 though...

Workaround - mixdown CD to one long 32-bit BWF file, open it with any program that has MegaBit option (I use IzotopeRX), make conversion to 16 and re-open this new file in the same project with "place at original time code". This remain all CD marks in your project intact. Takes some minutes.

Just out of curiosity, do you find the MBit dither superior to POW-r? How so?

Thanks,
Silas

Material dependent... Sometimes TPDF better. And I prefer old pyramix "acoustic" most of the time for pop and rock. Just IMO.

I've used Pow-R for years, and like it very much for classical music- choral music. With business slow, I'm not going to buy Pow-r right now. Better places for my money. I have Pow-r on my Sonic, and used to have it on a Z-Sys EQ box.

I'm very happy with Mbit, and it's in Sample Manager for Mac, for less than $80.

There is a website where you can take a blind test of dither:

http://www.24-96.net/dither/blind_shootout.htm

They compare 20 or so dithers. I took the blind test. I voted for Mbit 1. Pow-R was my second choice.

Also worth checking this link out:

Pyramix Acoustic NS is relatively close to POW-r 3 judging by these graphs.

The "mistake" of some Dither/NS implementation has been the misinterpretation of the Fletcher-Munson curves. They were once measured for frontal incidence of sound only. But speakers are 30 deg and earphones 90 deg lateral. So Fletcher-Munson does not apply there. Head related transfer function, no linear relation...

That is probably why my ears have a problem with the 9 kHz bump of many "sophisticated" NS algorithms (POW-r 3, MT Acoustic), which IMHO were designed only by looking at the (wrong) graph, the graph of the competition, or by drummers. :)

The best way to design good sounding dither/NS is to forget about F-M and concentrate on listening.
