I've narrated an entire lecture in powerpoint 2010. Playback sounded fine during my initial testing but apparently midway through recording the real presentation, I bumped the gain knob on my mic and the level dropped significantly for the remainder of the lecture. So, my question is: is there a way to increase the volume of an audio narration in powerpoint 2010 without re-recording it?
I'm thinking how you (in the olden days) could open a wav in sound recording and increase or decrease the volume then save it.
