Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput

[onlyconnect]

Just to clarify, the way it works is: connect DAC, download kernel #11 (or is it 12?), let it reboot and it sees the DAC?

Thanks

You have probably done some of this already. I used Kernel #11.

Just got my Aurilac Vega DAC today, and the async USB works great with EDO. I did have to use the large buffer setting to get 24/192 to work with the Vega's "exact" clock setting. For DSD64, I used Sonore's command-line dsf2flac program to convert a sample DFF file from 2L Records to a DSD-over-PCM (DoP) FLAC, and it worked fine. I haven't tried DXD or DSD128 yet.

Daverz,
Doesn't converting the file kind of defeat the purpose of DSD? Just curious.

No, DoP just uses PCM as the delivery format to the DAC. It's treated as DSD at the DAC end.

Edit: Now as to how the ESS chipset handles DSD, that's a different controversy...

DoP is a "packaging" format rather than a true conversion - the actual DSD data doesn't change.

Thanks, onlyconnect.

Gave it another try today. Don't see any major difference as to how I tried it (except perhaps starting with a cheap USB cable rather than going with the Supra USB cable via the iFi iUSB) but lo and behold, it worked (after the second try or so, switch to digital output first and then going back to USB). Both Kernel #11 and #12 made sound with my Esoteric's K-03 USB input. #11 showed adaptive mode, so I tried #12 and I was in async (Haven't gone back to #11 to try again). Putting the iUSB back into the chain presented no problem, as for switching in and out of the Esoteric's USB mode. Tried 44, 88, 96, 176, and 192 and they all worked. May have heard a glitch few and far between but it was so slight that I wasn't sure if it was a glitch or if it was part of the music. As for sound (can I mention it here?), initially it seems slightly more midrange heavy than when I was using the iFi iLink and feeding Esoteric's SPDIF in, but I haven't really used the Esoteric's USB input in ages so I will be giving it a little time to settle in and see how it goes (sound seems to have opened up a bit in the hour since I started playing music over it)

I continue to be amazed by the adaptability and possibilties presented by the SBT and am truly thankful that heroes like Triode are making things even more fun! Thanks!

I spoke too soon. The Vega stutters when switching between sample rates with the exact clock setting whatever buffer setting I use on the Touch. I have to back off to the clock setting to "auto" if I'm doing a lot of switching between sample rates. If I'm just playing one sample rate, the exact setting is OK. Not a huge deal, as the clock accuracy probably still beats most DACs out there.

Just a little more update regarding My SBT EDO kernel #12 Esoteric K-03 combo experiment.

So far, operation seems ok, with the exception that the glitch I think I heard before is not a hallucination. Regardless of what sample rate material I was playing, every now and then I would hear for fractions of a second what seems like a variation in pitch. It is short, it is subtle, it is not what I would call a tick, and it sounds somewhat like the fingers on your left hand slipped a touch when you play guitar. Anyone else experience something like this before? It is not a life and death issue but I am just curious. Also, is it normal for the sample rate (when I check the status of the USB output) to show something like 959998 rather than 960000 every now and then? I didn't check for other sample rates but it was shown momentarily now and then when I was playing some 96K material.

Thanks.

That means the async protocol is working. It checks the average rate of the data coming in and the rate at which it is being pulled out by the DAC and every so often tells the computer to slow down or speed up to keep the average data rates in sync. So those slight changes in sample rate are the system doing it's job correctly. If it never changes that means the async protocol is not working.
