You can make awesome animated PowerPoint templates and presentations but powerpoint let you move beyond that and assign a sound every time a slide is changed or advanced. To add a sound to the powerpoint slide transition you will need to go to Transitions tab and then look for the Timing section where Sound combo is displayed.
To add a sound to the transition, select the sound effect that you want to assign from the Sound combo like in the picture above. You can choose between a preset of sound effects to choose every time you move to the next slide. You can for example choose a Breeze sound effect, a Coin effect for financial powerpoint presentations, a Drum Roll for the last slide with Questions or any other sound effect like Hammer, Laser, Push, Suction, Typewriter effect for powerpoint, Voltage, Explosion, Chime or Cash register sound effect.
Many other effects may be available in your powerpoint version but you can also configure to Loop the sound until next sound which will start playing the sound until any other new sound is played in the presentation.
If you click Apply to All, then the sound and duration for the slide will be applied to all the Slides at once. This is very good if you want to apply the same sound to all the transitions for every slide.
How to add a custom sound effect to the powerpoint Slide Transition
Instead, if you don’t want to use a preset sound from the list but a custom sound then you can do that by choosing the option Other Sound… from the list. This option let you choose a .wav or sound file from the local computer to be used for the transition sound effect.
At any time you can remove the sound for the transition by selecting No Sound instead from the list.
