terrible feeling, I know exactly what you mean ^^

sounds great, I will! now all I need is a gapless DirectShow player

PS: damn, it really seems to sound different from foobar! cleaner and clearer, and 192kHz is great too, James I think a proper gapless audio part in SlyPlayer would be in good order

so far, perfect! and same for movies...I'm trying to see w/ Casimir666(MPC-HC coder) if he could possibly allow gapless FLAC/APE(he already allows it for BD .m2ts)

BTW, there's more and more audio interfaces that only support KS on W7, and not WASAPI...I know some ppl who use an old beta of Reclock(before it did WASAPI), if at some point you could allow choosing between the two this would be really handy!

for instance, this thing only does KS on W7(no DS, no WASAPI...it's an elite interface): http://www.head-fi.org/forums/f46/us...ml#post6242551

and apparently the VIA generic drivers(for all the AudioTrak/Onkyo and their OEM customers) only do DS and KS, just like on XP.

and about SQ? this guy says that foobar uses some boring "pattern" in bit-perfect: http://www.phasure.com/index.php?topic=692.0;all

and this other guy can identify FLAC/WAV/MP3 320kb/MP3 VBR 192kb blindly in foobar: http://www.head-fi.org/forums/f46/bl...0-kbps-461878/

let's just say that I prefer to put my ears between your hands(many ppl confirmed that your WASAPI implementation sounds better than foobar's, and even xmplay in WASAPI would sound very different...so much for bit-perfect huh ), madshi for madflac and the ffdshow/MPC communities(MPC's MP3 decoder works in 32fp and sounds very good).

and 192kHz upsampling sounds really amazing, it might be just that it does improve the DAC post-filtering or whatever: http://photos.imageevent.com/cics/v0...rts%20v0.3.pdf



strangely, the best external DAC's are those that reclock at 24/192(to kill jitter and increase filtering accuracy): http://www.camerahobby.com/Misc_DAC1.htm

apparently 44.1 is far more prone to jitter than frequencies w/o a coma?!

Hmm, that is weird. First, I thought KS isn't supported anymore - at least not by Microsoft. Second, my impression was, that if there is a WDM driver present, WASAPI will work.

EDIT: To put it in other words: If you hear Windows sounds with the audio interface, WASAPI should work. Maybe bad, maybe with really weird sampling frequencies, but it should work.

I never got KS to work with Vista & up.

However, if you want to try it ... start ReClock config and the player software (MPC, etc.) with XP compatibility mode. If this works ...

[leeperry]

KS definitely worked for me on Vista SP1 w/ an M-Audio Audiophile USB, it's still very much active in the new OS: http://code.google.com/p/cmediadrivers/wiki/Bitperfect

In Vista, the kernel streaming interface has been marked "deprecated", and it doesn't work with WaveRT versions of the driver, but it can be used with non-WaveRT versions.

oh well, I don't plan on moving to W7 anytime soon, just wanted to point out that many cards do support KS but not WASAPI

anyway, I've A/B'ed foobar against Reclock many times...I'd say that the stereo imaging is much better in Reclock...foobar is actually a good name

now if you could explain me(us) how bit-perfect can differ from player to player?!?!?! especially considering that DAC's are supposed to be immune to slight jitter

the XXHighEnd coder says that there's a truckload of jitter happening in the windows audio kernel....not that I'm surprised

the cMP coder advises to kill the windows shell.

I'm glad you like it. So, you'll say the new "audio only" mode is a success? I personally haven't tested it so much. In fact I'm a little concerned what might happen at the end of a song. Is the buffer properly flushed? Or are some samples missing? To test it, set the pre-buffer size to max (1 sec), and if I'm unlucky, 500 ms will be cut at the end of the song...

Apart from "snake oil" my guess is that I'm using a real-time priority thread to process a separate small WASAPI ring buffer, this implementation might just be the right thing to do. Dunno. Maybe I'm just lucky.

When James thinks that he's done with you, you always find a way to come with just one more request...

I am surprised. It should be easy to allow KS, but I have no way to test it, making things a little difficult. I could add a little secret registry key simply telling ReClock not to do "Vista things", so it will behave exactly like it does under XP. Only the automatic speaker configuration will not work.

The people with this "KS only" hardware can try the "compatibility mode" trick first. If this doesn't work, there isn't much sense for me to waste time.

ouh, realtime on HPET...no kidding

all the guys who bought the uber-low jitter interface I linked above said that the stereo imaging was just SO much better than anything they had heard before

I did compare the Asus STX/ST many times, and the lower jitter clock of the ST was *very* audible..much wider SS and clearer stereo image, the STX was unbearable in comparison...hah

as burson says on their page: http://www.bursonaudio.com/burson_clock.htm

The effect of the clock is instant; you don’t need to “Burn In” to hear the difference. [..] By reducing the jitter error, you will hear clearer positioning, also details are further refined vocally and instrumentally. Sound stage and positioning will improve noticeably and that includes deeper sound stage and darker background. Some said it also improves the control on the bass.

and how is KS handled on XP? realtime too

BTW, yes...you don't allow to set any latency like foobar?...when I had some strongly fragmented 24/96 5.1 FLAC files, foobar was struggling to put them back in once piece...MPC simply failed.

yes, 192kHz in KS sounds really great! on my few Bjork gapless albums, I get a nasty small gap between the songs but that's all...I will try what you said and report back.

and movies are just as smooth as before, it's getting odd....even CoreAVC CUDA 2.0 works fine in mVR+KMP apparently

No, I don't think so. I can't look at the source right now, but KS is exactly the way it was implemented by Ogo. I never touched it, and I really don't intend to. KS is dead. Erm, deprecated.
