How to you edit how high or low someone s voice befor putting it on youtube.

 Filmora (originally Wondershare Video Editor) allows you to change voice of video/audio and recorded voiceover. You can either click "Import" on the primary windows to import video/audio files to the User's Album, or click the voiceover button above Timeline to record your own voice. The imported video/audio files could then be added to the Timeline for editing, while the recorded audio would automatically appear on Audio track.

You can use an voice over app , such as Filmora or Viva video these apps & sites / tools can help you because you simply insert / import a video or audio track to edit and the rest will become clear once installed .

Saying once you import a video or audio transmission you will see what to do next , it goes off of your choices.

I really hope that my opinions / answers have helps you a lot with your question , have a nice day.

This isn’t even a question it’s just instructions for a question. can you elaborate???
