You can download some DXD for free from 2L - the Nordic Sound - follow the link to 'Test Bench' and scroll down for special resolutions. Dunno if they count as an experimental studio setup though

<edit> - ah, I see UnixMan already mentioned them

yup. What I did not mention is they those files appears to be band-limited (to about 20-22KHz) and with plenty of noise-shaping applied.

Looks like they are likely master files prepared for standard CDDA production...

Nevertheless, they sound terrific. (even after the sox downsampling to 24/192 which was required to be able to listen to them on my system).

Glad I didn't waste my HDD space trying to download them then. What's the point of having a heavily processed file in such a format? I have downloaded some of their lower res files and found them to sound impressive though.

Sweet. I didn't know that.

Anyway. If possible supporting these super-high-res formats is desirable, however my point was that there isn't really any material out there, is there?

Relatively speaking, no there isn't. I tend to spend my time getting better sound from all the 44/16 material I have rather than chasing hi-res. Wasn't it Holt's law that goes 'the better the recording quality, the poorer the music' ?

Now that SACD backups are possible, DSD playback will become increasingly popular.

Oh! that would be a big news! How is that possible? what hardware+software is required?

For hardware a SACD compatible PS3 with firmware 3.55 or earlier is required. The software can be found here.

Just curious.

1. Anybody out there who tried the impact - -- if there's any -- of earlier discussed PC optimizations?

Let's assume there are differences:

2. What do you guys think of the two stage jitter supression (widget + FIFO) +
the isolation (as done on exau2i) in between.

Not to forget:

All that should be able to run up2 8 channels of course. Over here we're still talking stereo - correct?
8*192khz might be considered a kind of challenge. Though the exau2i guys are setting the pace. That product IMO should
be considered reference for now.

Cheers

Default Hardware available now

Hi guys,

the full batch of AB-1.1 boards just arrived with me. That means I'll start shipping out complete units very soon, probably Monday. Here are some pictures.

I'll install a firmware image which is performing well with UAC1 (44.1 and 48) on Windows. UAC2 (44.1-192 on Linux and Mac) is in the image, but you'll need drivers and the WidgetConfig program to set it. Join the sdr-widget and audio-widget mailing lists for details.

The price is still $120 plus shipping ($31 international, $18 Europe)


Cheers,
BÝrge
