To adjust volume, select Volume and select the setting you prefer. To fade in or fade out audio, change the number in the Fade Duration boxes. To trim the audio, select Trim and then use the red and green sliders to trim the audio file accordingly. Then select which options you'd like to use: Select the audio icon and then select the Audio Tools Playback tab. If you’re using more than one audio file per slide, we recommend putting the audio icon in the same spot on a slide to find it easily.
To move your clip, select and drag the audio icon to where you want it on the slide.
Select Record to re-record your clip, or select OK if you're satisfied. To review your recording, select Stop and then select Play. Note: Your device must have a microphone enabled in order to record audio.
