Ok, this is merely for fun;

Look at the description below. THD is less than 0.0001%. That is goooood for a DAC. But what does it actually say ?

The two pictures show the result (measured at the output of the DAC) of feeding the ESS Sabre DAC with a pure square wave. The first picture shows what's left of it at 3000Hz and the second shows a nice pure sine at 10000Hz. I talked about that earlier in this topic.
To me the second picture shows a 100% distortion. But hey, what I do here won't be a measurement of THD (http://en.wikipedia.org/wiki/Total_harmonic_distortion). Right, but what to do with THD if this is the real life result ?

Ok, up and running here. Can't think of why it didn't work before, other than the rather unofficial way I stacked it (see the locomotive below).
Before I disassembled that several times at trying, so it wasn't about a loose connection I think. Now both halves are loose and everything looks right at first glance.

Must test it for its merits later; today there's visitors. And Chritsmas music only of course.

Merry Christmas to you all !
And thanks everybody for nothing less than sheer coorporating !!

I am confident that we are gathered here (blahblah) ... for being the best ears on the globe. At least I don't know of any forum being more serious at the level (of detail !) we are operating here.

Have a nice time with your beloved.
Peter



PS: Not a picture of this year ... yet.

Hey, thanks Leif. I will probably working on it tomorrow or the day after (in between eating stuff ).

Yep. However, everything keeps track of where playback is. E.g. bringing up XX, wait 10 seconds, and press play will restart playback at the position you last heard the music. Of course this makes no sense, but in the mean time you may have changed another parameter (like volume, "DAC Is" etc.).

Peter

It's okay Eric. Thanks.


which I doubt a little bitty bit.

When you drag the pointer (read : when you are dragging the pointer) the music does not stop. When you "drop" hence set the position of the pointer, then the music stops at the position where it was playing, and immediately continues at the position where you set the pointer. Note that "immediately" depends on the size of the file (part as per setting in the Settings Area). At this time XXHighEnd disappears again (only with Unattanded Playback of course).


Am I correct that this is your only left problem ?
Btw, I think you are right on this, but again depending on the file (part) size plus the speed of your system, you see this happening or not (I don't).

Peter

Without pressing any button ? nah ...
or ?


And it stopped because of what ?
I'm afraid you forget something to tell here. But what, I don't know ...

If you move the cursor, afaik nothing happens. Not if playing was unattendedly and you just brought up XX and then move the cursor. You must be clicking something else in between ...

If you bring up XX, move the cursor, and press Play, music continues where you put the cursor. At least that's how its meant to be, and that is how I think it works. But that is not what you seem to do ...

Hey Eric, thanks. I did not observe this, while extexsively using it at testing other things ...
What kind of files do you experience this with (WAV, FLAC, MP3, samplerate/bitdepth) ? One example is enough.
And what happens ?

Peter

Hi Ed,

Things worked out differently from what I planned.

1.
It appeared that it is not just a matter of attaching the Buffalo to the "powerplant" because the output of the Buffalo is + and - volt while the powerplant was setup for balanced DACs with + only, hence + and - connected (I hope you can follow what I mean, but this is about 2 DACs per channel, not in parallel, but balanced).
Of course I can change this, but it means work which implies work again when it needs to be reversed (and remember, this is only testing around a bit). So ...

2.
So I deciced to build the IVY and all, which was completed Sunday morning.

3.
From then on I'm struggeling with the Buffalo DAC ...
RCA out gave hum all over (and I mean MUCH hum and a little bit of music), and I decided to setup a balanced means of output. Officially my amps are not balanced, but since I planned to make 'm like so, it was a good reason to do it now.

4.
This means of "balanced", gives some (but too much) hum by itself, thus also to the NOS1 DAC.

One very well could say that right now I am in a big knot of ground loops and 10ths of meters of shunting wires are all over, and the one setup doesn't suit the other change (and creating one acceptable setup really takes hours).

And additional problem I have, is that I play without preamp, but when such a hum is exposed as the Buffalo does so far, this is not allowed (breaking windows). So, the pre-amp has to come in again, and that by itself destroys the ground loop setup.
So I'm in circles ...

But as soon I have some result, I will post it !
Peter

PS:

Hahaha, I gave a smart answer there. Now I better ask you Leif !

Hi Eric,

About the crashing : is this with virtual memory (hence using a paging file) On or Off ?

Generally, you should now limit the file size loaded into memory. In other words :
With the versions before April 2008 this problem was similar (but a real problem only when virtual memory was shut off), and at that moment things were changed in the memory environment;
What happened with 0.9w-5 is that everything kind of went opposite and theoretically more memory is used because of that.

What happens now is that each larger track (compared to the earlier played tracks) will reserve additional memory, but it will never be freed (on purpose) besides a relatively small piece (100-200MB or so, which varies up and down). So, the longer you play for one session, the larger the chance you bump into an again larger file.

All is solved (if everything is working as intended) by limiting the file portions loaded into memory. When you set that to e.g. 200MB and have a 24 bit DAC, approx. 10 minutes of 16/44.1 will fit into memory and each track smaller than 10 minutes will not be cut in two (or more). Larger tracks will, but that goes without notice.


Yep, and as "promised" in the release notes . I have it myself once-twice per evening, but it seems kind of standard for the last track of the playlist.
Btw, what you will hear is an amount of music that fits one "buffer-size" of the DAC and it is from the 2nd second (or so) from the last track played (so, you already heard it before ).
Since this seems a bug outside my reach somewhere, it is hard to solve. But I will ...

Thanks,
Peter

Is this different from what you had before ? (when you were "able" to create a Favorites file of 370MB !)
It looks like the same problem.

Can it be that somthing took longer than you wanted, and you clicked a Favorites link again while another one was pending, and that that initiated the real problem (things get in a loop and the file grows and grows) ?

This probably will occur with MP3's (I recognize the "UnicodeTrack" from that).

Will solve it !

What I thought before seems proven here;

There are several places where " - " (space dash space) occurs, and it will be this what goes wrong. So, this is just a strange means of naming tracks I don't anticipate upon.
I will look into it now.

Peter

I did not ... I just didn't go back because of apples and oranges anyway. As I told earlier, I was lazy.

Hi Rolf,

For now the quick solution (which should work because it works here) : set the combobox at the right to TextUnder.
I will look into it of course.

What version were you using while your setting worked ? (and to be sure for me, what was your setting for that combobox ?)

Peter
