Crossfading trouble?
« on: June 02, 2002, 02:34:47 am »

I find the crossfading working a bit funny since the optimizing of buffer handling in MJ8. My standard setting is 0.5 sec crossfading with wave out. But the crossfading only works on about 1/3rd of every song shift. The other times it just clips the ending song and starts the next directly (with some variations, ie fades up but not down)

I've tried several settings, DirectSound/Wave out, different crossfading length, different crossfading types...
Oh, btw the error occurs mostly when I shift songs in the middle of playing one.

Noticed something else. It seems definitvely that it has something with buffering to do. If I skip a song directly after another (with 1-20 sec delay) like three or four times a row, the crossfading breaks and will not return to normal until I played a whole song.
Does this ring a bell to someone?

Try:

Options -> Playback -> Settings -> Performance -> Move towards "More Skip Resistant"

Media Jukebox now sets the cross-fade, but then backs it off if new data doesn't start rolling in fast enough.  More skip resistance will help that.

Hope that does the trick... (let us know if it doesn't)

I too had the same thing happen to me.  I used 8.0.289 for a DJ job Saturday.  I have crossfade set at 1.5  seconds and had several songs clip off before the end and then the next track started up normally.  The system is a VAIO notebook with a P3 750.  I'll try setting the slider toward more skip resistance.

Sorry to say, adjusting the 'More skip resistant' slider didn't work out Next Page

I just did a new test. After putting skip resistance back to almost all the way to the right (does work, no skips anywayNext Page) I tried skipping the currently playing song with working cross-fade. Then I skipped 4 songs quite rapidly (1-3 secs between 'Next' clicks). Then it stopped working.
While I was typing this I let Marvin Gaye do his thing, and now tried again, back and forth. Now it didn't work, didn't work, worked, didn't work. Quite randomly...I believe. Could it be that MJ8 waits for album images (external) to load? I don't know...And no-one on the dev team has experienced this?
I put the reminder up again: It worked flawlessly before the build with optimization of the buffering.

Thanks for putting up with whiny users! Next Page

I'd like to retract my report and offer my apology.  It turns out that the tracks that ended too soon were themselves clipped.  They've been replaced.

So, as far as my complaint on this subject, in the words of Gilda Radner, "Never mind".

Good deal LCtheDJ.

And marty3d, I can't reproduce what you're talking about.

Just a few notes:

1) MJ doesn't cross-fade if the sample rate changes from one track to the next (would require resampling)
2) Cross-fading audio CD's is tough because most CD drives are a lot slower than the hard drive (are you playing CDA files?)
3) Is it possible that there's just a little silence, so 0.5 seconds isn't enough of a fade to show up?

Hopefully we'll figure this out...

Thanks.

Hi Matt! I'm not playing cd's, only mp3 songs. And I have tried several different settings of how long the crossfade should be...
After reading your last post, I tried to only play songs with the same bitrate. But no luck, the crossfading is as wobbly as usual Next Page
But I have another suggestion for trying to solve this: It should be possible to record the phenomena and send it to you since it's kind of hard to explain how it sounds? Not being a sound guru, I have no idea how to do this, but you might know? Then I also can include every step in a textfile. How about it?

Replying to myself again...Next Page
I noticed something else yesterday. If I set crossfade to 1 sec, then it works. Too bad I think it fades and start playing the next track too slow Next Page
But really! Shouldn't you be able to set crossfading lower than 1 second? Why on earth is it possible to drag the slider lower otherwise???
