Mp3 metadata only saved to first track when using export multiple based on track names

marcelloromani · September 29, 2024, 12:12pm

How to reproduce:

Create multiple stereo tracks
Ensure all of them are unmuted
Export Audio → to Computer → Format: Mp3 → Export range → Multiple Files → Spilt files based on: Tracks
Edit Metadata → Fill in Artist Name, Albun Title, Year, Genre, leave all other fields blank → OK
Click “export”
Result: all tracks are exported as separate mp3 files, but the metadata is only set in the first track
Expected: Metadata should be set in ALL tracks

bug P3 Design / UX regression Metadata import-export

### Bug description With new Multiple Files Export dialog (introduced in 3.4.x)… user supplied Metadata applies only to the first exported file - it does not carry through to any further files exported as part of the multiple export. This is a regression on 3.3.3 and earlier ### Steps to reproduce 1. generate a chirp 2. add three point labels: A, B and C 3. File > Export Audio 4. Choose **Multiple Files** for the **Export Range** 5. Click on the **Edit Metadata** button 6. Add user data for the blank: Artist Name, Album Title, Year, Genre and Comments 7. Click OK button - returns you to the Export dialog 8. Click the Export button 9. Observe: the first exported file has the full set of metadata 10. Observe: the second and third files only have: a) **Title** - _the B and C derived from the labels_ b) **#** or **Number** - **2 and 3derived from their export order** 11. Import the A, B and C files into iTunes 12. Observe: the only metadata is the **Song** name: the A, B and C ### Expected behavior The user's metadata should propagate to the second and subsequent files in a multiple export sequence ### Actual behavior The user's metadata does **_NOT_** propagate to the second and subsequent files in a multiple export sequence ### Audacity Version All 3.4.x and latest 3.5.0 alpha ### Operating system Windows 10 but assume all OS ### Additional context Reported more than once on the Forum: 1, https://forum.audacityteam.org/t/metadata-for-multiple-tracks-not-working-as-before/88607 2.https://forum.audacityteam.org/t/i-no-longer-see-the-export-multiple-files-option/94274/3 See also: **v3.4.0 Meta data set default not working on audio export #5494** ### WORKAROUND Before exporting, go to Edit > Metadata and click "Set Default" button.
