# Read a TikTok sound scan

A TikTok sound scan shows how many videos use a sound, whether that number is growing, who is posting and what kind of videos they make. This article explains each section, including the stage badges like **Emerging** and **Peaking**.

## The sound card

* **Sound Intelligence** shows the sound's title and artist, the label and distributor of the linked song when TikTok links it to a release, and a **Spotify** button.
* **The big number** is how many videos use the sound.
  * **Posts on this sound only** counts videos on this one sound.
  * Some songs have several sounds on TikTok, for example the official sound, a sped-up version and re-uploads. When Pulse knows about those, you can switch between **Merged** (videos across the linked sounds) and **This sound**.
* **Count details** shows where the number comes from, including how many videos were sampled for the rest of the scan. The sample is not the total.
* **Spotify streams** is the linked song's Spotify play count, when there is one.
* Below that you'll find the ISRC, UPC, release date and copyright of the linked song, and a strip of the top videos.

## Trend Trajectory and stage badges

Pulse checks the video count of sounds it knows about every day. **Trend Trajectory** charts that count over time, next to the linked song's Spotify streams per day, so you can see whether a TikTok rise is followed by streams. Use the menu above the chart to switch between the individual sound and the combined total. Viewing it doesn't use a scan credit.

The badge in the corner shows the sound's stage:

| Badge | What it means |
|---|---|
| **Emerging** | Early growth. New videos are starting to appear. |
| **Accelerating** | New videos are being made faster each day. |
| **Peaking** | Still a lot of new videos, but the pace has levelled off. |
| **Declining** | Fewer new videos each day than before. |
| **Dormant** | Few or no new videos. |
| **Unknown** | Not enough history yet to say. |

The marker under the title (**high**, **medium** or **low confidence**) shows how much history the stage is based on. A sound Pulse has only just started tracking will have low confidence.

Below the chart:

* **Group net growth / 24h**: new videos across the sound's group in the last day.
* **Group velocity / day**: the average number of new videos per day.
* **Last group count**: the latest total.

If the sound is new to Pulse, Trend Trajectory may not appear yet. It fills in as daily checks build up.

## The other sections

* **Videos using this recording**: a list of videos you can search by creator, caption or video ID. Click **Load merged feed** to include videos from the song's other sounds when they're available.
* **Genre & Trend Signal**: hashtags used with the sound, weighted by reach. Bigger tags carry more of the sound's views.
* **Spotify Streaming**: the linked song's typical streams per day and its trend.
* **Who's Posting**: how many sampled videos come from creators of each size, from **Nano** (under 10K followers) to **Mega** (10M+).
* **Engagement Quality**: the median likes, comments and shares per view in the sample, plus the top 10%.
* **AI Video Analysis**: what the top videos show and why they work, if your plan includes it. See "AI video analysis".
* **Top Videos** and **Top Creators**: the most-viewed videos and the creators behind them.
* **Markets** and **Credits**: where the linked song can be played and who's credited.
* **Where It Lives**: the languages of the videos in the sample.

## Common questions

### Why is the number lower than TikTok shows?

TikTok's app can add up videos across all versions of a song. **Posts on this sound only** counts one sound. Switch to **Merged** when it's offered, or open **Count details** to see what's included.

### Does reopening a TikTok scan use a credit?

No. Opening a saved scan is free. Clicking **Run fresh scan** uses a TikTok scan.
