Keep getting an error with "crossfade clips"

I closely read this topic and I have the exact same problem, but since the topic is very old and I am on Windows (Audacity v3.4.2) , I thought I’d rather open a new topic.
No matter what I do, I can’t get “Crossfade clips” to work:

  1. open a new project
  2. import a sample audio (here applause from a live recording, stereo, sample rate 44,1kHz)
  3. create a DTMF signal and append without a visible gap to 2) for crossfading
  4. select a range across the clip boundaries (a few seconds on each side)
  5. Apply “Effect → Steve Daulton → Crossfade clips”
  6. get an error: “…More than 2 clips selected”
    Zooming in into the boundary just shows the expected gap of one sample interval - no extra clip.

Experiments on the following variants (select range, apply effect) all resulted in the same error:

  • Joining the two clips and splitting them again
  • trying on splits inside clip 2 (applause) or clip 3 (DTMF)
  • trying even on joined clips (well, this IS definitely les than 2 clips selected …)

What am I doing wrong?

It’s a bug: Crossfade Clips fails when Audacity is set to Deutsch (German) · Issue #5848 · audacity/audacity · GitHub

I posted the fix here but unless you are familiar with editing Audacity’s translations your best option will be to work around the issue.


  1. Change the Audacity language settings. (English should work)
  2. Downgrade Audacity to an older version.

If you make two separate tracks you can make a “manual” crossfade.

oops - UI language setting was about the last culprit I would have thought of, Thanks a lot for sharing, @steve!

Thanks for the reference to Crossfade tracks @DVDdoug . I tried this already but it would have been quite some effort to pull out the to-be-faded clips into a separate track, so I thought I’d stick with Crossfade Clips.
