What is your operating system?
macOS Catalina (10.15.7)
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
Certain combinations of splits cause deformations in the exported audio. No movement or other editing required. Just splits in certain places will trigger the issue. Most of the time this doesn’t happen, so it takes some tries to intentionally reproduce the bug. In the attached example I made random cuts in the audio until the bug was triggered. The distortion happens about 8-10 frames in (around the beginning of the audio) and 1 second and 4 frames in (around the first cut). Along with the project I’m attaching the audio before and after splitting and logs.
