Voice changes completely when I change the speed for 150

I would like to know if it is possible to change the speed of the video without changing my voice.
When I accelerate 1,5 times, the voice becomes bizarrely high, like if the lowers were cut.
Thanks in advance.


The current version of ActivePresenter (8.1) doesn’t support changing audio without changing pitch. You can use a professional audio processing software like Audacity (https://www.audacityteam.org/) to process audio before importing into ActivePresenter. In the case you just want to change video speed without changing audio, you can follow the below steps:

  • Insert an audio object by clicking Insert > Audio > Create New.
  • Go to Properties > Audio > Source and click Select an audio from the project button.
  • In the Select an audio dialog, select Video in the toolbar.
  • Select the video resource which contains the audio that you want to keep.
  • Click OK.
  • Select the video object, then select Volume tool in Timeline to set its volume to 0.


Thanks for your help!
