Sound: Your Secret Growth Engine While Why It’s So Challenging to Master

In today’s scroll-driven world, sound isn’t just background—it’s what makes people stop and feel. According to Markopolo.ai, 88% of TikTok users say sound is essential to the TikTok experience, showing how deeply audio shapes engagement. Vidico reports that videos using trending sounds see 66% higher engagement, and TikTok’s algorithm favors sound-based content (Influencer Marketing Hub).

What’s more, 71% of users decide whether to keep watching within the first 3 seconds (Influencer Marketing Hub), making emotionally aligned audio a critical factor in grabbing attention.

Yet, while capturing footage may be straightforward, perfecting the audio layer presents its own set of challenges.

• Recording synchronized voiceovers is a meticulous and time-consuming process.

• Choosing the right sound design requires a nuanced understanding of what works for your content and platform.
