which are the two kind of sound effects files in Microsoft PowerPoint that can be added to the presentation ?
Answer: A
Correct answer: .wav files and .mid files
PowerPoint takes two kinds of sound: .wav files, which hold a digitised recording of an actual sound, and .mid (MIDI) files, which hold instructions telling the sound card which notes to play. The .gif and .jpg extensions belong to still images and carry no audio.
