What an AI music extender does
An AI music extender uses the source audio and your written direction to create a possible continuation. The source provides musical context, but the result is a new section to review for timing, harmony, voice, instrumentation, and energy.
Describe the next section
Ask for an intro, verse, bridge, instrumental break, outro, or a longer version of the current section.
Review the join in context
Listen across the transition and check tempo, harmony, voice, instrumentation, timing, and energy before keeping the result.
From source audio to a longer version
1. Choose audio you can process
Select a completed Soundful AI song or upload an MP3 up to 100 MB that you have the right to use.
2. Direct the missing section
Name the section, mood, instruments, vocal direction, and energy you want after the selected point.
3. Judge the transition
Play before and after the join, then keep the continuation only when it serves the original track.
