Background music for voiceovers, ads and short videos
Start with your finished edit’s length. Adapt these example prompts to the scene and the space you need beneath speech.
Voiceovers and narrated explainers
Measure your finished narration and create an instrumental bed at that length. Start with sparse instruments and a steady pace. Listen with your voice track, lowering the music wherever the words need more room.
Example prompt
Soft piano and warm ambient pads, slow steady pulse, restrained melody, instrumental background for a calm explainer.
Short ads and product promotions
Set 15 or 30 seconds for the whole ad, including the final product shot or call to action. Describe the energy and mood, then preview against the picture. File length does not guarantee beats will match each transition.
Example prompt
Bright electronic percussion, clean synth chords, upbeat and confident, instrumental backing for a short product ad.
Short videos and social clips
Match the music to your finished recipe, travel clip, Reel or Short. Choose a lighter arrangement if the video includes dialogue or location sound. Download the MP3 and check the mix on speakers your audience might use.
Example prompt
Light acoustic guitar, hand percussion, relaxed sunny mood, a simple instrumental rhythm for a short travel video.
Podcast intros, outros, and transitions
Try 5–15 seconds for a short transition, then adjust to your actual intro. For an outro beneath closing remarks, leave room for speech and add a fade in your editor if needed.
Example prompt
Mellow electric piano and soft bass, warm conversational mood, simple instrumental cue for a podcast introduction.
Product demos and screen recordings
Use a restrained instrumental bed beneath cursor movements, captions and narration. Set up to 120 seconds for your segment. Listen through repeated sections and lower the music around key instructions.
Example prompt
Minimal synth pads, subtle electronic pulse, calm focused mood, instrumental background beneath a software walkthrough.
Choose a duration from your timeline
You can enter any whole-second length from 5 to 120; the examples below are starting points, not separate generation modes. Measure the section that needs music after your main cuts are in place. Include a title card or closing shot if the track should cover it.
| Track length | A useful starting point | What to check in your edit |
|---|---|---|
| 5–10 seconds | Quick intros and scene transitions | Keep the musical idea simple. Check whether the opening and ending feel comfortable over such a short section. |
| 15 seconds | Compact ads and product reveals | Include the final product frame in your timing. Leave room for the spoken message to remain clear. |
| 30 seconds | Short voiceovers and social clips | A useful length for a first guest preview (free preview covers up through 60s). Listen with your narration before deciding on the sound. |
| 45–60 seconds | Narrated explainers and tutorials | Use a steady arrangement and check the full track for sections that distract from the explanation. |
| 90 seconds | Walkthroughs and longer product scenes | Listen for repeated musical phrases and decide if they suit the pacing of the footage. |
| 120 seconds | Extended demos and background segments | Check transitions and the final ending in your editor. Fade or rebalance the track around spoken instructions. |
Audio may be trimmed or repeated to match the selected file length; a longer track does not promise new musical development throughout. Guest free previews cover up through 60 seconds (15/30/60), limited by preview count. Longer tracks need sign-in and credits.

Frequently asked questions
Set the length, leave room for your voiceover, and know what to check before using the MP3.
Can I use it as background music under a voiceover?
Yes. Generate an instrumental bed for the length of your narration or scene, then mix the MP3 with your voice track. Optional AI narration is available in Horror TTS for signed-in users, in English or Mandarin. TTS narration is synthetic, AI-generated audio. Listen to voice and music together and lower the music wherever speech needs more space.
How much does it cost? Do I need a subscription?
Optional Creator ($9.90/month, 150 credits) and Pro ($19.90/month, 350 credits) subscriptions include a 1-day, $0 trial with 10 credits and a card on file. One-time packs remain available when you prefer to buy credits as needed. Music credit cost depends on duration and is shown before generation. Horror TTS costs 1 credit per successful synthesis and requires sign-in.
Can I get 15, 30, or 60 seconds—or the 42 seconds my edit needs?
Yes. Enter any whole number from 5 to 120 in the duration control, including 15, 30, 42, or 60. Measure the section that needs music, including opening or closing shots. Use the prompt to describe the sound. Audio may be trimmed or repeated to match the file length; separate generations can produce different music.
Can I hear a track before buying credits?
Yes. Guest free preview covers up through 60 seconds (15/30/60 presets and custom lengths in that range), limited by the number of free previews and rate limits. Longer tracks need sign-in and credits, up to 120 seconds per track. Demo samples are also free to hear on the site.
Will the music end naturally? Will there be repeated parts?
The selected duration sets the file length. Audio may be shortened or repeated to reach it, so a precise runtime does not guarantee a resolved musical ending or a seamless loop. Listen through the track, especially joins and the final seconds. You may still want to adjust the volume or add a fade in your editor while listening with your narration and picture.
Your video has a length. Your music should match.
