Audacity Forum

Hi rhkrhk and anyone else interested in this subject, Started just a few weeks ago with the conversion of my old vinyls using Audacity and had the same idea as you: Audacity should have a way to create track separators on the fly, while listening the LP. After downloading the Audacity source code, I...

Thanks Edgar for showing me the way to this code fragment which I could copy to and use in SelectionBar.cpp without any compiler problems: AudacityProject *p = GetActiveProject(); if (p) { p->SkipEnd(true); double playRegionStart, playRegionEnd; p->GetPlayRegion(&playRegionStart, &playRegionEnd); } ...

In SelectionBar.cpp I need the length of the current track, thus the 'Audio Position' resulting from the 'Skip to End' knob being pressed.
Where can I find that info and how can I make that info available in the SelectionBar class?

Thanks for any suggestions!

How long you have to wait for my output, Steve, I don't know.
But a bit of patience will be necessary, I am afraid!
Thanks anyhow for your remarks!

Any patches have to be submitted to audacity-devel mailing list as per http://wiki.audacityteam.org/wiki/SubmittingPatches until you become an established developer. No developers read this Forum. Gale Thanks for the link Gale, didn't know. Contributing to open software appears much more complex th...

In order to become familiar with the code and structure of Audacity and of wxWidgets, I started simply and added a small modification to Repair.cpp, of which the main purpose was to clarify about that unnecessary 128 sample restriction. I widend it to 150 as to remove any suggestion that a power of ...

In repair.cpp -> EffectRepair::Process() the repairLen is restricted to a maximum of 128 samples. Change it to for example 512 samples and see how long Repair takes then. Gale OK, Gale, so there is an almost cubic relation between repairlen and processing time, due to the use of matrices. However t...

In repair.cpp -> EffectRepair::Process() the repairLen is restricted to a maximum of 128 samples.

The applied Least Squares AutoRegressive Interpolation method imposes no theoretical maximum.

So does anybody know where else this maximum stems from and why a power of 2?

Thanks, jerome42

it must be possible to write software that automatically does what my eyes can do: detect and draw-repair those cracks without introducing new impairments. I assume you found Effect > Repair (limited to 128 samples). What Audacity lacks at the moment is high quality click detection (and of course a...

Yes, I dropped my own two-years old win32 C++ project to automatically remove clicks and cracks from my old vinyls after finding Brian Davies' ClickRepair. In the last 2 years I tried numerous methods for automatic crack detection, in the time- as well as in the freq. domain (FFT), but couldn't find...
