Cross fade, pitch, Playback issue

[ruben12345]

I had this playback problem before. I'm using the latest build on ipod photo 60 GB. When you increase the pitch, crossfade fails to work properly. You get a mighty glitch as cross fade begins and then later the track plays alright, and in some cases the ipod hangs. When you crossfade without pitch shift the crossfade is proper. Any help on this issue. Or could it be resolved in the forthcoming builds ?

Please state your revision number, rather than saying "the latest build" since "the latest build" changes very, very frequently.

revision no. 17150 and all the builds over the last 2 months or so. Things were fine just before the metatag project.

[Llorean]

There is no such thing called the "metatag project." What exactly are you referring to?

[karashata]

I -think- he's referring to the Metadata on Buffer project that NicoP had been working on which has long since been commited to SVN and polished up...

[Llorean]

I would suggest that he probably isn't, since that was committed LONG over 2 months ago, so couldn't possibly be what he's referring to if he's saying the problem is only over the last 2 months or so. As well, I'd really like to know where he got the name "metatag project" from, because I've seen other people referring to such a thing.

[karashata]

Oh, my bad...  Perhaps I'll see if I can't find out what people are talking about.

The mention of '2 months' seems to be inaccurate, if a previous topic from the same poster can be relied upon:

I use crossfade a lot with pitch range 105-110 without problems. Helps to play songs faster especially for techno kind-o-stuff. But...... all builds upto sometime around end september were fine. ...... Unfortunately, there's some problem in all the builds thereafter i.e. the entire "november" builds.

EDIT:
I've tried crossfading with pitch in the range 105-110 on a number of mp3s of varying bitrates (80-320kbps) and have not encountered any problems with r17196.

Yeh, Sorry ! I was talking about the metadata on Buffer project. I guess I got the phrase wrong. But as I said, all builds after around 2007-11-27 to be accurate (after the MDB project was initiated) have a problem with crossfade if you use any pitchshift above 100%.

By the way, there's no build r17196.

I tried even yester day's build r17164 - has a problem

I've tried resetting all the settings, no equi, no extra bass, treble settings nothing. When you crossfade into the second track with any pitch shift the 2nd track begins playing erractically, with ugly gaps then starts playing normally. I'm an avid user of rockbox over 2 yrs now - I cannot go wrong on this one. Besides if  I use my 2007-11-27 build its perfect with or without pitch shift.

Any feedback

Rockbox is up to r17203 now, and there was a 17196 at the time of his posting. You are aware of the "Current Build" page, correct? The most up to date build comes from there, not the Daily Build page, which is for archived builds.

Seriously though, if this is the same problem you reported in the other thread, why did you start a new thread? You got an answer there.
