TikTok and the Rise of Sound Intelligence: What BGM Says About Your Audience?
Understanding the emotional and behavioral impact of sound on audiences.
On TikTok, silence is invisible — sound is everything.
Every scroll on TikTok begins not with what you see, but with what you hear.
The beat, the remix, the melody — that’s what drives virality, emotion, and recall.
TikTok is the first platform where sound powers the algorithm.
From trending audios to branded jingles, background music (BGM) shapes how audiences feel, interact, and remember.
And yet, most analytics tools are still deaf to it.
That’s why Tars Tech built Sound Intelligence — a part of our multi-modal AI platform that interprets sound as data, emotion, and culture.
The New Language of Sound
Music isn’t background anymore; it’s a storytelling device.
A sound trend can spread faster than any hashtag — and when paired with visuals, it becomes a shared emotional experience.
But traditional analytics tools were built for text and images, not tone or tempo.
They miss the nuance of rhythm, voice, and the emotional signals that make audiences hit replay.
What Is Sound Intelligence?
Sound Intelligence is the ability to analyze and interpret the impact of background music, voice, and audio tone across video content.
At Tars Tech, our multi-modal AI analyzes over 200M+ TikTok videos every day, processing 10,000+ data points per second across 100+ analytical dimensions — from genre and mood to emotional resonance and audience reaction.
Our Sound Intelligence engine identifies:
🎶 Mood & Genre — upbeat, emotional, nostalgic, intense.
🔊 Audio Dynamics — rhythm, volume, pitch, and tone.
📈 Behavioral Impact — replay rate, retention curve, comment sentiment.
This combination translates sound into measurable emotional data — the missing link between creativity and conversion.
Real-World Example
A beauty brand used Tars Sound Intelligence to identify upbeat BGM styles that matched their audience’s preferred emotional tone.
Within a month, their TikTok replay rates increased by 25%, and average engagement time grew by 22%.
When brands understand what their audience hears, they understand how their audience feels.
Why BGM Matters
80% of TikTok engagement happens through sound, not text.
Audio drives memory retention more effectively than visuals alone.
Music sets the emotional rhythm for every piece of content.
Sound Intelligence allows marketers to go beyond mentions and measure emotion at scale.
The Tars Advantage
Tars Sound Intelligence transforms sound into strategy — giving brands the power to listen like audiences do.
With real-time, multi-modal processing, Tars turns short-form video data into emotional insight, showing why trends resonate before they peak.
