In Reply to: sounds like i missed out on a great pillow fight :-) posted by Christine Tham on June 26, 2004 at 16:43:28:
Hi Christine, I inquired in 'good faith', whether or not Racer had a definitive and up-to-date MLP client list to back up his assertion. I was genuinely interested and intrigued, as I am sure others here were too.Indeed, I assumed that Racer must have a definitive source regarding his refuting of Wilkes (re. the issue of Philips Electronics' license of MLP compression). As you know, the issue of Philips’ exclusive loyalty to SACD (or otherwise) has been an subject of contention on the AA in recent weeks, and that examining this latest statement from Wilkes, with the help of Racer, could shed some useful light on the matter for readers here.
b.t.w. The fact that Wilkes (who seems like a sincere & reputable chap, as far as I can tell) mentions the issue of Philips in the way he has, to me, signals that something has indeed happened, aside from the fact that the company -- as you state -- already produces universal transports.
However, Racer (who conveniently dismisses the credibility of Wilkes in a few words), instead of kindly sharing his claimed information with all of us here on this forum, would rather engage in a both stupid pissing contest and a pointless game of internet ‘hide-and-seek’.
As for the thread in general (the one which I linked to), it also shows how newcomers to hirez have indeed lapped-up the DSD misleading marketing hype with all that nonsense of the ‘high sample rate’ of one-bit SACD and using that big-number to compare directly with that of multi-bit PCM. And then it is amusing to see how that same poster has subsequently realised the error of his ways.
FWIW, The other aspect I found interesting was the mention of the internal 32bit mixing & DSP resolution of the system which Wilkes uses. This shows that what I have repeatedly said was theoretically possible with hirez LPCM, is indeed being put into practice.
Finally, like you, I did find the detailed description of his system components for hirez & surround-sound production quite fascinating.
cheers, Martin.
Follow Ups:
even my old copy of Cool Edit does all processing internally at 32 bits floating point.So does your Denon DVD-A11.
Other packages will also do 32-bit integer, but i prefer 32-bit floating.
The new Intel HD Audio specification (in their latest generation 915/925 chipsets) will process up to 8 channels of audio at 192/32.
Unfortunately, none of the first generation motherboards implement the spec very well, using either the C-Media 9880 codec (SNR only 92 dB - less than 16 bits resolution!) or the RealTek ALC880 (100dB SNR DACs, but ADC hobbled to 20 bit at 85 dB SNR)
I was hoping to upgrade my HTPC to the latest chipset, but now it looks like i will need to wait a bit longer.
Sure, apart from Cool Edit, I was aware of those other examples which you mention (esp the Denon's own internal DSPs which are 32bit, and also the Intel spec).The Wilkes example is an interesting case study (for an industry outsider like me) which shows how 32-bit is also being used directly in the studio. Now, especially with the new Intel spec, I reckon we will see a lot more of this (32bit) resolution throughout more of the audio chain.
