Audio plays a significant role in how viewers connect with video content. With PosterMyWall’s new Timeline editor feature, you can easily add, edit, and enhance your audio tracks, making your videos more immersive and engaging.
Key features of the Timeline editor

1. Add multiple audio tracks
You can easily add and layer multiple types of audio, including voiceovers, background music, and sound effects (SFX) in your design. Background music sets the mood, voiceovers help with the storytelling, and sound effects (SFX) can highlight specific moments, such as text animations/transitions or on-screen actions, in a video. With PosterMyWall’s Timeline editor, you can seamlessly combine these audio elements to add depth and the right emotions to your videos.
2. Trim, stack, and arrange audio
The flexible timeline allows you to drag, trim, and arrange audio tracks with precision. This way you can align the audio tracks precisely with your video’s visuals.
3. Apply audio effects
Enhance your videos with professional audio effects, such as fade-ins and fade-outs. These effects help create smooth audio transitions and add a polished, cinematic feel to your content.
4. Integrated audio library
Don’t have any audio to upload to a video? No worries! Browse through PosterMyWall’s extensive audio library to find the perfect sound for your project. You can access a variety of free music tracks of different genres, instruments, moods, and effects.
