Problemas con el audio al renderizar

Hola,
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?
Gracias!!
Juan.

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.
