Record audio for a specific location in a presentation
At
times, you may need to record and add some audio to a specific location within
a presentation. (To record audio, you must have a microphone or recording
device plugged into your computer.)
In PowerPoint, open a presentation (PPT file).
From the Adobe Presenter menu, select Audio Editor.
Click the location within the waveform to which you want
to add new, recorded audio. For example, if you have an audio file
playing on slide 1 and you need to add audio at the start,
click the beginning of the audio file on slide 1. You can
add audio to any location on the waveform, even a location that
does not currently have audio.
From the Insert menu, select Recording.
Set the type of recording device you are using by clicking
the drop-down menu under Input Source and selecting either microphone
or line in.
Set the Volume level at which the recording should be
made. The default setting is 100%. To change the setting,
slide the volume slider bar to the left or right.
To set the optimal recording level and sensitivity for
your input source (microphone or line in), click Calibrate.
To begin recording, click the Start Recording button and
begin talking.
