Unable to import song at correct tempo if wrong tempo detected #6425
Comments
Even worse - if I change the Preference setting "Import / Export > Music Imports" to "Do Nothing", the track is imported at double speed without any indication that Audacity has changed the tempo. |
The behaviour for automatic tempo detection can be found in the pull request: In the steps to reproduce, in step 5, instead of clicking No, if you click Yes, and then press Ctrl+Z to undo, this will result in the desired outcome. Note that if you're importing into a non-empty project, with the timeline view set to beats and measures, and the automatic tempo detection is incorrect, then the speed adjustment of the clip will be incorrect. If the timeline view is set to beat and measures, then there is no way of turning automatic tempo detection off, despite what is stated in the current documentation for automatic tempo detection: |
FWIW I believe this is the exact same issue as #6285 |
That issue was that automatic tempo detection was failing in an apparently simple case. |
No, it's a different issue. #6285 is about the accuracy of tempo detection. This issue is about the problem caused when tempo detection gets it wrong (as it inevitably will on occasion).
Thanks David. A useful, though counterintuitive workaround for some cases. |
@DavidBailes if you answer "No" or have settings saying "never", the auto-stretch happens only in Beats and Measures view. (Confusing probably is that if you're already in B&M view, the dialog will still says "enable music view and ...") |
I assume that by that you mean that the preference is only about reconfiguring the view and the temp of the project? |
I think that users will typically expect import behavior to be consistent regardless of the display mode of the timeline. |
I have a different experience. My timeline is B&M, I import the previously exported 200bpm rhythm track, and this gets the clip stretched. Consistently with the preference, nothing happened with respect to project view or tempo.
That's another problem, isn't it? |
The preference is "When audacity detects music in file imported on empty project: I guess our takes on this are different.
It probably is. |
Schrödinger would be proud. |
Bug description
I have a music track with a tempo of 200 BPM. When I try to import it, the tempo is incorrectly detected as 100 BPM.
It seems to be impossible to import the track at the correct tempo.
Steps to reproduce
Expected behavior
The file will be imported into the project without changing the tempo or time signature.
Actual behavior
The file is imported at double speed.
