Multiple export without changing metadata

Hello :smiley:,
I wanted to know if it was possible to do multiple export without changing metadata.
I would not change the title and the artists participating in the details.

Sorry for my poor English :unamused:

Enter the Artist Name metadata before exporting, at File > Edit Metadata Tags…, then that field will be filled with the same Artist name when each metadata window appears during export.

The Track Title metadata is automatically filled in each metadata window according to the labels (if you export multiple by labels) or the names of the Audacity tracks (if you export multiple by tracks). The only way to make the Track Title metadata of each song the same is to make it the same in the labels or track names.

If you do that and you don’t want any other metadata fields to be filled, there is no need to show the separate metadata windows when you export because each window will already be filled with the information you want. So in that case you can turn off Metadata Editor in the Import / Export Preferences.

If by title you mean Artist Title, you can enter that once before you export instead of entering it in each window.

Perhaps he did not understand me well. :cry:
I speak of the metadata editing. As seen from the attached file, when I make multiple export, automatically, in the " Artist name " ends the artist’s name last loaded audio file and instead the " Title Track" it all ends the song name. :nerd:
I would avoid this so as not to modify any data of my music files. :exclamation:

That is exactly what I replied about. You did not mention the problem was about already existing metadata, so I assumed your question was about writing metadata when there was none.

Audacity only stores one set of metadata for each project, which is the metadata for the last file that you imported. There is no solution, other than to change the metadata by hand when exporting, or import one file per project window using File > Open… .

You can request a feature for Audacity to store separate metadata for each track if you want, but it is not likely to be implemented unless a developer is interested in doing it.

Unfortunately many files and then I find it difficult to edit them in turn. :open_mouth: :astonished:

Where can I apply?

Is metadata the only thing you are changing, and are these MP3 files? If so, you should use a tag editor such as http://www.mp3tag.de/en/ - this will avoid you re-encoding the MP3 just to change the metadata. Re-encoding an MP3 is always lossy.

If you are changing tags and the only other edits are changing the volume or cutting pieces out, you can make all those changes using a direct MP3 editor like MP3DirectCut which can edit directly without re-encoding.


I added your “vote” at http://wiki.audacityteam.org/wiki/Feature_Requests#Other_Import.2FExports.

They are mp3 files.
I’ll explain, I want to improve the sound of my music passing from 128 kbps to 320 kbps.

If that’s all you are doing, sorry, I don’t know why your metadata is getting changed…

But if you’re not editing the audio, you might try [u]TAudiConverter[/u]. It’s easier to use because once you’ve got the output location & format set up you can just drag-in the files and click “Start” and you can convert a batch of files.

That won’t automatically improve the sound. In fact, it can make it worse because you are going through another generation of lossy compression. It’s sort-of like copying a DVD or VHS tape to Blu-Ray and expecting Bl-Ray quality, or like changing a low-resolution photo to a higher resolution format.

MP3 is lossy compression. 128kbps files are smaller than 320kbps because more data is thrown-away. That information is permanently lost. Re-encoding to 320kbps (or to WAV) makes a bigger file but it doesn’t bring-back the lost data. (If that’s confusing, think about a silent 320kbps file that contains no useful audio data, but is the same size as a 320kbps music file.)

If you want to edit the MP3 or “improve” the sound by applying some effects (noise reduction, EQ, reverb, etc.), then if you want to save-again as MP3, a higher bitrate might help to minimize the damage done by re-compressing. But whenever possible, you should work with lossless formats and compress once to MP3/AAC, etc.

The metadata is being changed in Audacity’s metadata editor because the project only holds metadata from the last imported file.

As Doug says, merely re-encoding the MP3 at 320 kbps, if that is all you are doing, will by definition make the files worse, even if you can’t hear the degradation. Don’t do that.

Regardless of what he is trying to, I thought he might get more help here as his question was pretty straight-forward. I also need to be able to export multiple tracks WITHOUT touching the existing metadata of each and every track. I have a Cadillac CTS Coupe that has the ability to play music via a usb stick. It’s cool but the only thing is that it’s PICKY AS HELL! It will not play any track that is not 320kbps. I have used Audacity to make all tracks work in the car’s mp3 player but each and every song says it’s by the same artist and same album… because Audacity FORCES the changes of metadata. There has GOT to be a way to simply disable metadata overwriting. Is there a way to or will I have to ditch Audacity?
