Exact-length background music for your finished edit
Start with your finished voiceover, ad, or short video. Enter the number of seconds the music needs to cover, from 5 to 120, then describe the sound. Your instrumental MP3 matches that length, ready to place beneath the edit.
A 30-second ad can use a 30-second cue; a 42-second explainer can use a 42-second bed. Set the runtime in the duration control and describe the music in the prompt. Keep the story timing you have already chosen.
Set 15, 30, 60, or your own seconds
Choose a preset for a short ad, a social clip, or a narrated product demo, or enter your own whole-second length. Include any title card or closing shot that needs music. If the section runs 17, 42, or 73 seconds, use that number instead of stretching the picture to reach a round duration.
For a new cut with a different length, generate a separate cue. Separate generations can produce different music; these are not guaranteed versions of the same melody or arrangement. The range is 5–120 seconds per track, with guest previews limited to 30 seconds.
Background music for voiceover, with room for speech
For an exact-duration instrumental bed, describe what belongs beneath your narration: a gentle pulse, a few instruments, and a simple melody. Try “soft piano, warm pads, light percussion, calm instrumental background for a spoken product demo.” Bring your own recorded voiceover; the generated track supplies the music underneath it.
Even an instrumental can distract from words. Listen with your voice track and lower the music where speech needs more room. If the cue feels too busy, try fewer instruments or less energy in another generation. Mixing and volume changes happen in your editor.
Check how the ending sounds
Exact-length music means the audio file matches your selected seconds. Music may be shortened or repeated to reach that length, so it does not guarantee a resolved musical ending or a seamless loop. Listen through the whole cue, especially repeated sections, joins, and the final few seconds.
Add a fade in your editor if it suits the scene, then check it with the picture and narration. Ending at 30 seconds does not promise a musical accent on your final frame. The timing placeholders above contain beeps and silence; they demonstrate file length, not generated music or musical endings.
Take the MP3 into your edit
Download your track and import it into a video or audio editor that accepts MP3. Place it beneath the section it was made for, then balance it against dialogue and sound effects. Listen to the complete mix before publishing.
For Reels, Shorts, or a short promotional video, use the actual cut length as your starting point. For a video longer than two minutes, work with individual sections within the supported range. Each section needs its own check for timing, musical fit, and transitions.
See the cost before you generate
Use one-time credit packs, with no subscription required. The tool shows the credit cost for the duration you select before a paid generation. Check it as you change the seconds: a credit balance is not a fixed number of tracks.
A limited guest preview is available for a track up to 30 seconds without signing in. Longer tracks require sign-in and credits. Check your current preview allowance in the tool, and review the available credit packs when you are ready to make more music.

Can I get exactly 15, 30, or 60 seconds of music?
Yes. Choose the number of seconds you need, from 5 to 120, and the tool delivers an instrumental MP3 at that length. Use the duration control to set the runtime.
My voiceover is 42 seconds. Can I use that length?
Yes. You can enter any whole number from 5 to 120, including 17, 42, or 73. Measure the section that needs music, including any opening or closing space you want to cover.
Should I put “30 seconds” in the prompt?
Set the seconds in the duration control. Use the prompt for the sound: mood, pace, style, and instruments. For example: “Warm piano, soft percussion, a restrained melody under a product voiceover.”
Can I use it as background music under a voiceover?
Yes. Generate an instrumental bed for the length of your narration or scene, then add the MP3 beneath your voice track in your editor. Listen to both together and lower the music wherever speech needs more space.
Does it generate singing or the voiceover itself?
This tool creates instrumental background music without lyrics. Bring your own recorded voiceover; the generated track supplies the music underneath it.
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.
Will I still need to edit the audio?
The MP3 comes at your selected length. You may still want to adjust its volume, add a fade, or change where it starts in your scene. Make those choices while listening with your narration and picture.
Can I make 15-, 30-, and 60-second versions of the same song?
You can generate separate tracks at those lengths. Separate generations can produce different music, so do not expect the same melody or arrangement to carry across every version.
What do I download, and how do I add it to my video?
You download an MP3. Import it into a video or audio editor that supports MP3, place it on the timeline, and balance it with your other audio.
Can I make a track longer than two minutes?
The supported range is 5–120 seconds per track. For a longer video, use the tool for individual sections within that range; it does not create a complete longer soundtrack in one generation.
Do I need a subscription?
No. The tool uses one-time credit packs. The credit cost depends on the track's duration and is shown in the music tool before you generate. A credit balance is not a fixed number of tracks.
Can I hear a track before buying credits?
A limited guest preview is available for a track up to 30 seconds without signing in. Longer tracks require sign-in and credits. Check the music tool for your current preview allowance.
