For creators whose music runs out before the video does
More music, same sound
Choose how many seconds to add, run it, and download the longer file.
Add seconds to a track
Pick any length from 5 to 60 seconds and the track keeps going in the same style.
Fit the music to the video
When a 30-second song sits under a 45-second Reel, add the missing seconds instead of looping the same bar.
Steer it with a prompt
Add a short note, such as calm piano ending or a bigger drum build, and the new part follows it as closely as it can.
Trim and speed are free
Cut the result to the exact length, or change its speed, in the same Edit tab. Those two edits cost nothing.
Listen before you download
The longer file plays in the result card. If it is not right, change the prompt or the length and run again.
Pay for finished files only
The extend price shows before you run. A run that fails is refunded automatically.

AI Audio Extender FAQ
How does the audio extender work?+
The model listens to the end of your track and writes new music that continues from it in the same style, tempo and instruments. The result is your original followed by the new part, saved as one MP3 file. The new part is generated, so it is similar to your track and not a copy of an earlier bar.
How much can I add?+
Between 5 and 60 seconds in one run. You can run the tool again on the longer file to keep going, though quality is best when each step is short. The source file for extending can be up to 2 minutes long, and a longer file can be trimmed first at no cost.
Will the join be noticeable?+
Often the continuation flows naturally, but there is no guarantee that the join is invisible. Tracks with a clear steady beat extend best. Tracks with a strong ending, a spoken voice or a sudden change are harder. Listen around the join, and trim the result if you need to cut out a rough spot.
Does it work on speech?+
The extender is designed for music and sound beds, not for voices. If you extend speech, the new part will not contain meaningful words. To make new speech use Text to Speech, and to make new music from scratch use the Music Generator.
How much does it cost?+
Extending is one price per run, shown on the run button before you spend anything, whatever length you choose. Trim and speed are free. Credit packs are listed on the pricing page.
Do I need a subscription?+
Pay once with credit packs, or go monthly. Pack credits never expire. Failed runs are refunded. You can open an account for free and look at the tool before you buy credits.
