When I use the 24Bit Output depth in MJ, MJ cuts off
the last 3-4 sec of every track. This is not happening with
a bitdepth of 16Bit. I use the default Wave Out.
The checkbox 'Do not play ... silence' is not marked.
I use MJ 8.0.348. It also happens with 336 and 320.

Anyone else having the same problem ?

What am I doing wrong ?

Does it cut it off only when there isn't another file coming, or when the next file is a different format?

What does cross-fading do?

Thanks.

That's really a quick reply ! ! !

 -- Does it cut it off only when there isn't another file coming --

No, cuts off when there is coming another file. It's within a playlist.

 -- or when the next file is a different format? --

It doesn't matter if there comes another trackformat.
I tested it with WAV and APE files.

 -- What does cross-fading do? --

I even tested crossfading with a duration of 16 sec.
At 16Bit all is OK. At 24Bit there doesn't happen any crossfading.
It's cutting of the last 3-4 sec like in Standard mode.

Does it fade right when you manually change tracks?  How about smooth seeking?

And does Direct Sound work any better?

Finally, will you paste your system specs (MJ -> Help -> System Info) here?

Thanks.

-- Does it fade right when you manually change tracks? How about smooth seeking? --

It's fading correct when changing the position within a track.

 -- And does Direct Sound work any better? --

I can use DirectSound only with 16Bit. At 24Bit I get an error Message from MJ and the
system crashes; then I get the blue screen ( exeption) and I have to restart the computer.
For now I'm not sure if I should be able to use 24Bit DirectSound when I can use 24Bit
Wave Output.

I'm not sure what's happening.  Updating the sound card driver might help.

Do you have a 24-bit sound card?  If not, Windows is just "pretending" and downscaling anyway, so it doesn't really do anything putting MJ in 24-bit mode.

And can anybody else reproduce this?

Thanks.

I think his problem is the soundcard doesn't support 24bit and windows is doing something funky or something.

I have a sblive5.1 (no 24bit support), using wave-out 16bit, gapless...  I put on a cd (apl files) where the music continues though the songs, so there isn't any silence...  with 16bit picked it sounds correct, can't tell when song changes.

If I pick 24bit/waveout it isn't gapless.  Theres like a .25s pause...  probably not even that long... its like when you rip a live cd to mp3 and you hear that really really short pause between songs, same thing here.

Hi Matt,

My Soundcard is a Terratec EWX 24/96 and supports 24Bit.

I will explain a little bit more in detail what happens.

Let’s say for example a track has a duration of 3min 34sec. You can see the elapsed time during playback in MJ down left in the ‘Player Window’.
You see 00:01 .. 00:02 .. till 03:24
When the track comes to an end at the last 10 seconds, the display switches and MJ counts backwards from –0:09 .. –0:08 ….. –0:01 .. 0:00. Then the next track starts.
That’s what happening at 16Bit Output depth.

But, . . . at 24Bit it’s quite different.

MJ also starts counting back from –0:09 .. –0:08 .. and so on. But suddenly, at –0:04 , the backcounting stops. You see the word ‘buffering’ for let’s say ½ second and then the next track starts.

I can’t imagine that this should has something to do with my soundcard.

During testing I found out exactly one case at which the error does not appear.
If I play the last track in a list and ‘endless playing’ is set Off, the current track ends up correctly and MJ stops.
So when there is no further track to play, all seems to be OK. But as soon as there follows another track, MJ starts buffering and cuts off 4 sec from the end of the current track.

This is only happening ( like I said ) at 24Bit Output depth.

Can anyone else check this at his own system ?

How are your results ?  -  -  - Please let me know

Thanks

It sounds like you need to move the Options -> Playback -> Advanced -> Performance slider towards "More Skip Resistant". (try that, stop and restart playback, and see if the problem persists)

Hopefully it'll do the trick.  If not, we'll keep plugging...

Thanks Reiner.

-- Options -> Playback -> Advanced -> Performance slider towards "More Skip Resistant --

The more I put the slider to "More Skip Resistant", the more seconds are cutted off at the end.
The most are 6 sec. Only when I move the cursor completly to "More Responsive" I get
not one second cut off. Isn't that strange ?

I never thought that this could have an impact to the problem.

For now the problem seems to be resolved.

But I don't understand the solution. If I have the possibility, I will try this out on another
Computer with a faster CPU. Perhaps this will help. I'll see.

Matt : Thank you for your quick help.

[Matt]

I wish I had at least a little clue why that was

Let me know if you learn anything new about this.

Thanks for your help.

I see it messing up too, mine was already set all the way to more responsive.

Actually something seems messed...
16bit / more responsive / 60 second second song
it goes 50 51 52 53 54 -5 -4 -3 -2 -1 0 1 2 3 and all is well


16bit / more skip resistant / 60 second song
it goes 50 51 52 53 54 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 and blah

Thats sorta messed, it isn't -10 at 55 seconds, the reason it sounds normal is because from -10 to 0 its not ticking down 1 second at a time, its takes it only 5 seconds

So 2 wrongs make a right... its starting the countdown 5 seconds late, but counting down twice as fast.

24 bit / more responsive / 60 second song
50 51 52 53 54 -5 -4 -3 -2 -1 0 1 2 3 and all is well

24 bit / more skip resistant / 60 second song
50 51 52 53 54 -10 -9 -8 -7 -6 0 1 2

Here theres only 1 wrong and nothing to cancel it out... it starts the countdown late but doesn't count down twice as fast.

Thats what its displaying, dunno what its doing internaly because thta doesn't really explain whats happening to the sound.


Actually I'm guessing more responsive = no buffer, more skip resistant = 5 seocnd buffer...
and what its doing is at the end of a song it isn't waiting for the buffer to empty before beginning the next song, it begins the next song soon as it finishes reading the current song.

Tho I dunno whats really going on, cept I can reproduce the messed up timings easily, and it does skip the last 5 second or so with 24bit/buffered.

[Matt]

Thanks for all the details BEXX.

We'll play around tomorrow and let you know what we come up with.
