Noise Removal Tool layers tracks?

[shackmaster]

Hello, I am recording from vinyl and have put each side of a double LP on separate tracks (well audacity did it for me when I started recording the new side). As you can see, I have labelled all the tracks and then normalized them. My problem starts when I then apply the Noise removal effect.......

As you can see, each track is now on top of the other with the resulting jumbled playback.
Is this a bug or am I doing something wrong?

Exact Audacity version and which Windows?

Sorry, new I should've included:-
XP SP2 and 1.3.9

Audacity 1.3.9 has some very amusing instabilities. Can you back up to an earlier version?

I would also invite you to download the 1.3.10 nightly build, but I don't know how to get to that on the PC.

I think that's a bug. None of the other built-in effects behave that way. I have confirmed that it occurs on 1.3.10-Nov20 on Mac. So upgrading to 1.3.10 won't help.

I hope you were able to Undo the effect and get all your tracks lined up with the labels again.

I'm afraid you'll have to apply the Noise Removal effect to each track separately.

In the future, use the Time Shift tool to drag the contents of tracks 2, 3 and 4 onto track one. I will make your life easier.

Thanks guys, at least I know it's not me.
I was able to undo and apply NR to each individual track, although it produced an interesting effect on track 4....

I'll try Bill's suggestion in future.

thanks again.

Or you can get Audacity to continue recording for you after stopping. Just click SHIFT+Record or SHIFT+R - this will cause Audacity to continue recording at the end of the Audacity track.

(Don't try it if you have multiple tracks though - it will give an error message.)

Really? Which version of Audacity and what error message?

V1.3.9

and it gives what seems to be a somewhat unrelated error message: "Error while opening sound device. Please check the input device settings and the project sample rate."

IIRC this error message is normally seen when the no. of channels on the input device doesn't match your settings in Audacity.

Do you think this is a bug Steve?

If no tracks are selected Audacity appears to try to record to all tracks. If the number of channels to be recorded doesn't match the input settings then that error message is technically correct if a bit unhelpful.

If you select one track then press SHIFT + R then it works.

So, should SHIFT + R throw up an error message telling the user to select a track for append-recording rather than throw up that unhelpful error message?
