Title: 0.9y-4 - Crack Detect tripped when Arc Prediction enabled
Post by: Calibrator on October 12, 2009, 04:41:34 am
Hi Peter,

While listening to Yellow's new album "Touch Yellow" earlier, tracks 11 & 13 tripped the "crack detect" coding when using AP with either Double or Quad resampling. Disabling Arc Prediction allowed those two tracks to play fine, even with plain Double or Quad. Perhaps your crack detect code needs different trigger criteria for when AP is used.

See attached screen grabs for when doubling and AP was used.

Cheers,

Russ

BTW ... I'd rate the new Yellow album at about 3 1/2 stars out of 5. There's the typical Yellow sound and instruments, but the whole album only has a couple of standout tracks. The bass is nice and tight though as you expect from them. They need a new trumpeter too !!

G'day there Russ,

I guess I will be having the album myself soon, so I will look what is special about those tripping tracks.

Thanks for mentioning it !
Peter

Well, let me start with telling I like the album very much. Maybe somewhat less Yello (for synths) than before, but still. One small problem, here nothing trips. BUT :

I use the digital volume, and I think this can matter. Now, since I don't like it much to reorganize my cabling an everything (the first thing what would happen is that movies won't produce sound at a next attempt :swoon:), would you care to attenuate the digital volume to -9dB and try again ?

I tried all the combinations of Double/Quad and Invert, but no trips for me. :)

Thanks very much !
Peter

Hi Russ,

After a good night of sleep, I came to the conslusion that I asked a ridiculeous question; I switch off the amps several times per day for testing something in the danger zone, and I can do that in this case just the same !
So I will.

Peter

Well that appears to have masked the issue and both tracks played OK.

I then tried again with Vol set at -1.5dB and track 11 started up fine, however track 13 still brought up the error. Dropping the Vol to -3dB saw track 13 also playing OK after that.

So we have a solution, but not the reason, why this album ( so far ) is unique in its data structure.

I'll leave the ball in your court on this one now  :scratching:

Cheers,

Russ
