Problemas con el audio al renderizar

Escribo porque me he dado cuenta de que, al renderizar un proyecto, en el archivo generado el audio tiene a autonivelarse y se sube y se baja el volumen automáticamente según la intensidad de la música.
¿Cómo puede corregirse esto?

Google Translate:

I am writing because I have noticed that, when rendering a project, in the generated file the audio tends to self-level and the volume is raised and lowered automatically depending on the intensity of the music.
How can this be corrected?
Thank you!!

Maybe you have a filter on your track or on the master output. The effect you are describing can be caused by the Normalize: One Pass Audio Filter. Maybe you have applied that? If you can share a screenshot of Shotcut with your project open, we might see a clue.
