A "pop" in the beginning of an audio clip even with fade in

Hello Rui!

Did not notice this before or else this did not happen before, but lately what happens is that when an audio clip begins playing and if it has sound right from the beginning, it has an audible "pop" (and if there is Delay in the track, this "pop" gets multiplied). But what is bad is that even if you do a fade in and so the beginning should be dead quiet, a pop still occurs.

Anything I am doing wrong or is this expected behavior?

probably not your fault. i'll have to look (hear) at it as soon as i get my hands on a reproducible sample of this behavior ;)

cheers

Fade it in almost to the end. You will hear a pop. If you do not fade in - there is no pop.

confirmed. there's a glitch/pop on the start of the audio clip and seems to only occur when a long fade-in is set; having a shorter or no fade-in at all doesn't expose any glitch, afaics...

it also only seems to happen on quadratic and cubic fade-ins; linear is ok.

i'll investigate and dig deeper...

cheers

[UPDATE] i guess i've nailed it :) svn trunk rev.2678 (aka. qtractor 0.5.3.11)

Thank you, Rui!

Oh, my usual confusion. I get qtractor from KXStudio updates (I don't run KXStudio, just use their repo). If I want to instead use daily builds, should I first uninstall the qtractor I have or can I just install over it?

Re: Oh, my usual confusion.

it depends... what are those "daily builds" ?

however, you can build yourself from source (eg. from my snapshotsand most importantly run it from the building place (src/qtractor)--you don't need to run make install at the end, if you only want to test whether a couple of things work better (or not :))

cheers
