1.3.6 Click Removal and Export Multiple?

I have been using Audacity 1.2.6 to rip my old LPs from a USB turntable.

Some of them have scratches, and the "Click Removal" Effect in 1.2.6 is very good at removing them.
1.2.6 has some flaws, so I tried 1.3.6 which has a better Label Track functionality.
But what happened to the "Click Removal" Effect in 1.3.6? I can't find it.

I use "Export Multiple" to save the ripped tracks to individual mp3 files.
In 1.2.6 I get prompted once for the album title, artist and year, but have to exit/restart Audacity to enter information for each new album.
In 1.3.6 I get prompted once for each track and have to reenter the title, artist and year for each track.
None of the methods are ideal, but the 1.2.6 behaviour to me is better than that of 1.3.6.

Otherwise it is a great tool!

In Audacity 1.3.6 the effects are in categories (making it easier to manage large numbers of plug-ins). Look in the categories to find the effects (Click repair is still included).

You can bring up the Metatag editor at any time from the File menu. If you enter the information that is common to all tracks before you start the Export Multiple, then you only need to add the bits that are different for each part.

You can switch off the Metatag prompt altogether from within Preferences.

Note that WAV format does not support metatag data.

Thank you for a prompt and qualified answer.

I found the "Click Removal" tool (under Effects -> Utility -> Noise Removal), and it works just as well as in 1.2.6 (cleaned my very scratched Joe Cocker, Something To Say album beautifully).

You are correct that filling in the Metatag info prior to using Export Multiple will fill in the fields, but I still have to confirm for each track.
I do not find this optimal or intuitive; if I fill in these "album general options", I would expect the program to take them as defaults and not bother me with a tedious prompt for each track.
Well, that was what 1.2.6 did, but for the duration of the program. What I really want (and find most sensible) is the program memory to be per album recording (an audio track in Audicity terms).
Put in other words; if I fill in Album info in the Metatag info, Audicity should remember it for the duration of an album recording (an audio track in Audicity terms), rather than for a track or a recording session.
But I understand that the best behaviour may depend on your working procedures, and it may be difficult to incorporate everybodies wishes.
Anyway, I still find it easier to exit/restart Audicity between each recording and have it prompt me ONCE for the album info during save than to edit Metatags and confirm for each track.

And I think this is good practice too - much better to start with a clean Audacity workbench (otherwise Audacity will still be storing the whole undo history of the orevious recording).

If you set Preferences so that Metadata editor does not pop up at export, and fill in your tags once before export multiple, then those tags will be applied to all the files without prompting you. See:
http://n2.nabble.com/Export-tedium-tp11 ... 29621.html

A few people have asked for metadata to be stored per track, so we'll add your vote for that on our Feature Requests page on the Wiki:

Thanks for the work and the explanation, Gale. It works fine.
This one has puzzled me a lot, since in 1.3.4. you could set the album title to (automatic).
However, still one remark: in [Export Multiple], you still get the option [Include audio before first label]. Isn't this a bit reduntant, because the first label is now [MR] by default?

I don't think "Include audio before first label" is redundant, in fact we have just made a fix so that it isn't disabled when choosing "numbering consecutively". Can you clarify (and I'm not sure what you mean by [MR}...

Thanks

This is getting weird... I did a test run on my laptop, and inserted some labels on the fly. When I stopped the recording and checked the labels, I saw a label right at 00:00 named [MR] which I thought didn't put there myself.
Repeating this on my home computer didn't get me the [MR] label. Then I found out! On my home computer, all keyboard shortcuts are default.
On the laptop:
P play
spacebar pause
M add label at playback position
(I find this more conveniant)

The following happens:
say, I would make labels on the fly: a,b,c etc.
I type M for the label, A and [enter]
I type M for the second label, B and [enter]
I type M for the third label, C and [enter]

output: I get the label A at the position where I typed it, and a label MB at 00:00 (!)
Label C is at the right position again.

I don't know why this happens.... but it was because of this behaviour that I wondered whether the [export audio before first label] wasn't redundant. When you have a label at 00:00 you don't need this option!

Actually, I find it quite conveniant this way. It makes the export of MP3's even more silent. Just fill in the artist and album name in [file/open metadata editor] hit [export multiple] and go! Otherwise -how it was meant to work- you have to fill in the artist and album name first in the metadata editor, and then again, in a totally different screen, you have to fill in the name for the first tag. To me this doesn't look logical neither user friendly (sorry.... ;) )
So, what I suggest is that Audacity could make its own label at 00:00 when you start adding labels while recording.... and skip the [export before first audio] option.
Does that make sense in your opinion?

You may be suffering from a fix for a problem that's been plaguing people. Labels are misnamed. They are Beginning Clip Labels, not Separator Markers. People put one Label between two songs on a single timeline and are shocked when they only get one export. You need to put a Beginning Clip Marker at the [/u]Beginning[/u] of each clip you want exported. So the above example calls for a Label at 00:00 and then another one between the two songs. That will give you two exported songs.

In your case, I bet there is new code to automatically put a Label at 00:00 no matter what you do.

Thanks Paul. It seems you've uncovered a bug there - if you change the "add label at playback position" shortcut to an unmodified character, the second time you use the shortcut when playing or recording, the label will be placed where you started the playback or recording (not necessarily at zero).

"Include audio before first label" (if used) in the export multiple dialogue determines the file name, not any metadata tag.

Labels do also function as "region markers", not just "beginning of clip markers". So when recording or playing you could drag regions out on the screen, CTRL + B (not CTRL + M) to label each one in turn, then multiple export the regions. An unmodified shortcut works OK for this.
