I'm working on a school project and we're given audio clips to use for lip syncing practice but one of the requirements is that the audio clips need to start at the bare minimum after 6 frames. At the moment, when I import the audio it begins to play immediately. Is there a way I can move the audio clip to where I need it? I know Krita doesn't show a visible waveform for audio, so I don't know what to do.

Sorry, that's not possible. Please use a dedicated video editor like kdenlive to combine audio and video if the requirements are more complex.
