Lalal.ai's job is separation, not generation: bring an existing recording — a song, an interview, a voiceover recorded somewhere noisy — and get clean stems back. Versely's isolate_audio does the same underlying job, and works on any audio_url, not only tracks Versely itself generated — it's the general-purpose tool for pulling a usable voice out of noisy source audio, explicitly distinct from the Suno-only stem splitter used elsewhere in the app.
What that separation actually does, and where a dedicated specialist still has a real edge, is below.
Any recording, not just a Versely one
isolate_audio works on any audio_url — a phone-recorded voiceover, an old interview, a downloaded clip — removing background music and instrumentation and returning a clean vocal track. That's a deliberately different tool from split-a-song-into-stems, which only works on a track Versely's own generate_music already produced.
Rescuing a take, not just remixing a song
The most common real use isn't music separation at all — it's pulling clean dialogue out of a recording with a loud environment underneath it, prepping a voice for dubbing or translation, or salvaging a good performance that was recorded somewhere it shouldn't have been. attach_audio_to_video puts the cleaned track back onto a video once it's isolated.
Where a dedicated separator still wins
Lalal.ai has iterated on separation models for exactly this one job for years, with dedicated stem types for drums, bass, guitar and more beyond a simple vocal/instrumental split. Versely's own documentation for isolate_audio is direct about the trade-off: separation quality depends on how the source was originally mixed, and heavily layered or low-quality audio isolates less cleanly on a general-purpose tool than it might on a specialist one.
Same session as the rest of the edit
Because isolate_audio runs in the same app as everything else, a cleaned vocal track can go straight into a dub, a caption pass, or back onto the original footage without exporting to a separate service and re-uploading the result.
How it works
1. Supply the mixed recording
Any audio_url with unwanted background music or noise under the voice.
2. Run isolate_audio
It separates out the background and returns a clean vocal track.
3. Reuse the clean track
For narration, dubbing prep, a cleaner mix, or just a usable voice out of a bad recording.
4. Reattach if needed
attach_audio_to_video puts the isolated voice back onto the original footage.

Frequently asked questions
Does this only work on music Versely generated?+
No — isolate_audio works on any audio_url, unlike split-a-song-into-stems, which only works on a track generate_music already produced. It's the general-purpose one.
How clean is the separation compared to a dedicated tool?+
It depends on the source mix. Versely's own documentation says heavily layered or low-quality audio isolates less cleanly — a dedicated separator like Lalal.ai, built and iterated on for exactly this one job, can still be the better call for a difficult or dense mix.
Can the cleaned track go back onto the original video?+
Yes — attach_audio_to_video lays the isolated vocal track back onto footage once it's cleaned up.
Is this for music, or can it rescue a bad voice recording too?+
Both — the most common use is rescuing a voiceover or interview that has background noise or music underneath it, not just splitting a song into stems.
