Editing a pre recorded .key

Question

ALot has changed since I was in Keynote last, I have a keynote done by someone else and I need to do the following/
make the audio.mov file louder ( I have an audio editing tool was able to do but I cannot get the audio to playback the same way.
I see no audio settings like in older Keynotes nor do I see anything else as the original keynote plays back as a timed file with slides changing different times for each slide. I do not see where this is in each slide nor do I see anywhere to adjust the audio.
Any help?
I'm in 10.9.5 Keynote 6.2.2

Answer 1

make the audio.mov file louder
As there is no function in Keynote to increase sound levels you should use a sound editing application that has the ability to increase gain, then save as an mp3 or AIF file.   Audacity, Compressor, Final Cut, Sound Recorder are examples.
Sound levels can be reduced using the volume slider in the Audio Inspector
I see no audio settings like in older Keynotes
Select the sound file on the slide, and make changes in:     Inspector > Format > Audio
the same audio functions available in Keynote 5 are available in Keynote 6:
reduce sound volume
change the in point or outpoint
set to loop
as a timed file with slides changing different times for each slide
select the slide in the navigator panel and change settings in:     Inspector > Animate > Start Transition
then change the option in the drop down menu to:   Automatically then set a delay time
