Description Paul L 2015-06-01 16:41:19 UTC

This is a regression from 2.1.0, and likely my fault.

Comment 1 Peter Sampson 2019-06-12 12:45:15 UTC

Testing on W10 with 2.3.3 alpha audacity-2.3.3-alpha-267-f320612f10e44f212c28175a57172a5811d30608

I can see nothing wrong with the generated chirp in Spectrogram view (but I'm no spectral expert).

Is this still a bug, has it been fixed?

I tested on 2.1.0 and on 2.3.3 - and I can see no difference between the two spectrogram views

I don't see the problem either.
Which version of Audacity had the problem? Was it only in an alpha build?
