When To Speed Up The Audio

Speeding up the audio is a good idea when you want to add energy and excitement to your content. For instance, in videos where you need to show a lot of action or movement, faster audio can match the pace and make things feel dynamic. Speeding up music can also make it more lively and engaging, which is great for upbeat scenes. Additionally, if you have longer recordings that you want to make shorter without losing important information, increasing the audio speed can help maintain the content while saving time.
