I am looking for a video editor app on both Iphone and Android phone, better if free and accessible on both platform. I have tried several, the problem is that I cannot see audio track with most popular editor, such as Inshot. By visible I mean that one can actually see the audio wave intensity to determine which part has sound or not. Now I have to listen, mark and clip manually, which is time consuming. Is there any editor app with visible audio track? Like the picture below, so I can quickly locate and edit parts of people talking. Thank you!
