That's extremely interesting -- and quite esoteric!  But (pun intended) it's upsetting my basic system for quantifying things!

Nobody checked the graphs: > check out this website http://src.infinitewave.ca/.... and especially the r8brain PRO minimal phase against ALL of the others ? ???

Allow me to slide a bit OT here, but will the iZotope 64-bit SRC be available for the PC-platform anytime soon?

Also, is the r8brain PRO processing in 64-bit, like several of the other Voxengo plugs. Didn't see that mentioned on the website.

Bob Boyd wrote on Mon, 02 April 2007 11:26 The current SRC in sB is not iZotope's nor is it evidently the classic SRC that so many people refer to liking from the older system.  While it has gotten some positive feedback, I find the current "built-in" SRC as utilitarian in nature.  As mentioned before, Sonic has licensed iZotope's for implementation at some point. I'm watching iZotope and trying the Sample Manager demo but at this point in time, I'm using Weiss Saracon.  Great SRC. It's funny Bob, I used to like soundBlade's current SRC (which isn't the iZotope at the moment). I still think that despite the aliasing it can sound great on certain material, can't explain the affect I hear but it kind of has a smooth soft sound which is great on some stuff. The iZotope SRC on it's high setting in WaveEditor can be a touch on the bright side but is likely the steepness of the default filter setting. See the attached image of the 'high quality' default setting in the current WE 1.2 version. With these being adjustable in 1.3, I bet we will get an amazing sounding SRC suitable for any style of music. With iZotope products it's all about high quality but giving the consumer all the options to create just what you need. MBIT+ is another example of having many options. Matt

I'll be interested to see how the iZotope SRC sounds once the parameters are adjustable.  It felt bright to me initially too.

Any idea what Sample Manager is using to dither the output file back to 24 bits?  Is it MBit+?  

I've been using pow-r on any SRC in Saracon.

What I also like about the company is that they are open about forthcoming releases and features. At Apple, you would already have been sacked for posting a screenshot to a forum...

He'll be hearing from our lawyers.  (Just kidding)

I hope I am not out of place responding on this forum.  If so, my apologies.

Wave Editor 1.3 will bring a couple of other improvements with regard to iZotope's 64-bit SRC:

1)  it will be multichannel (>2)
2)  it will have 64-bit input

Ahhh! good to have you here Matt

Just to clarify what Matt has said further, at the moment the iZotope SRC implementation in 1.2 has 32bit input & 64bit internal DSP within the SRC. Whereas 1.3 will accept 64bit on the input as well.

I had this happen when I first tried Saracon too.  You need to increase the buffers in the Preferences panel.  The manual mentions this but may not stress it's importance. The optimal settings will vary from computer to computer but try opening the first buffer all the way and the second one about 3/4. (I'm away from my studio computer so I don't remember what the faders are labeled.) On my Dual 2.7 G5, a STEREO file going from 88.2k to 44.1/24 with pow-r will (at it slowest!) be over 2x realtime.  Expect much faster results on the whole.

Hey Bob:

I tried your suggestion and Saracon is lightning fast now. Thanks for the tip.

I'm sure this doesn't affect the quality of conversion or does it? Do you know?

[Bob Boyd]

Nope.  Just optimizes the processing.  Better, huh?

Ah...sooo much better
