Audio

The Audio Player feature allows you to import audio files to an effect. You can control the volume as well as the play mode (single play or multiple loops). You can also pin the Audio Player as a visual scripting node. This will enable you to control the play status by connecting to the Audio Player Controller in real time.

Tip

Only MP3 audio files can be imported. Audio files with 44,100 Hz sampling rates are recommended. Other sample rates will get compressed. Please wait for the audio assets to be successfully imported. If the audio asset has a restriction from the music rights holder, you will receive a red warning icon on the Assets panel. This warning icon means that the audio asset cannot be uploaded to TikTok. Please click retry to upload the audio file if you receive a yellow warning status.

We’re currently not supporting audio recording by using the screen recording feature from the Preview panel

Preview on TikTok

Your audio effect will be recorded from the microphone of your phone, don’t cover your mic if you want to have a high-quality result. And if you wear earphones or headsets, the audio effect cannot be recorded.

Tip
Tip

If you don’t want to lose the details of your audio effect, don’t check on the Noise Reducer on the top right of the screen

Use VO and TikTok songs with audio effect

If you select a TikTok song before recording, the song will cover all sounds from the video. This includes the microphone speaker and the in-effect sound.

If you select the TikTok song after recording on the editing page, the sound in the video (including the microphone and sound in the effect) can play with the TikTok song together.

Adding a voiceover is totally fine, it won’t affect the embedded sound at all.

Performance Impact

Audio player and related audio features will generally not cause any frame rate reductions, but keep in mind that too many audio nodes or audio + segmentations combinations can impact your effect performance.

Visual Scripting

Types of audio nodes

There are two types of audio nodes we provided:

  • One is to control audio play.
  • One is to detect certain features of Audio that could use as a trigger.

Control audio playing

Control the Play, Stop, Pause, Resume, and get on Play, On Stop, On Finish statues of the Audio Player component in the Audio Player Controller node in visual scripting.

Add the Audio Player component that you want to control into the graph by clicking “+”> Get Audio Player, you can see the Audio Player node is in the graph now.

Connect the Audio Player node to the Audio Player Controller node on the graph panel.

You can now control the Audio Player in the graph panel. Here is an example of how to play the audio in loop one time by clicking the screen.
