If you want vocal continuity, provide only original lyrics or lyrics you have permission to use.
Compare the handoff, groove, instrumentation, and vocal continuity. Regenerate when the result does not fit.
Choose Music Extender for new musical material, not noise cleanup, time stretching, remixing, or audio repair.
Preview a rights-cleared MP3 locally before it is uploaded for extension.
Choose the extension direction supported by the current workflow: add generated music before the source or after it.
Provide lyrics you own for a vocal continuation, or leave the field empty for an instrumental direction.
Compare both players and judge continuity yourself before downloading the generated audio.
Generate an intro or outro for a rights-cleared background track, then review whether the transition works with your edit.

Choose Song Analysis, Lyrics Recognition, or Basic Chords for a rights-cleared audio source.
Separate songs into vocals, drums, bass, and instrument stems for remixes, samples, karaoke tracks, and DAW sessions.
Master songs online with AI analysis for EQ balance, LUFS loudness, dynamics, stereo width, and release-ready WAV or MP3 exports.
Turn Dark Ambient ideas into ambient music tracks that leave room for meditation apps.
Control orchestral strings, dynamics, and loop length so cinematic music fits artist sketches.
Start from piano and Lofi Hip Hop references, then shape lofi music tracks for course modules.
MeloLab Music Extender is a focused music-continuation workflow for creators who have a short demo, loop, instrumental, or song draft that needs a new beginning or ending. Upload a rights-cleared MP3, choose whether to add an intro or outro, optionally provide original lyrics for vocal continuity, and submit a real extension job. The result is newly generated musical material, so it is different from repeating a loop, stretching time, remixing the source, or repairing noisy audio. Continuity is not guaranteed: compare the source and result for transition quality, groove, instrumentation, and vocal consistency before publishing.
Listen to the source and generated result together. Check the transition, groove, instrumentation, vocal continuity, and ending before deciding whether the extension belongs in your final edit.
A song extender AI generates new musical material before or after the source. It does not simply repeat the same bars, stretch the recording, remix the song, or act as an audio enhancer for repair and cleanup.
Useful when a hook, loop, or intro works but the edit needs more runway for a CTA, transition, stream bed, or game scene.
