Export and download
Free MP3 stem download allowances on web and mobile, plus member-only Mix and WAV exports. Standard splitting and instrument practice stay free after a download limit.
#Stems or mix
| Type | What you get | Good for |
|---|---|---|
| Stems | Each ticked stem as its own file; several at once come as a zip | DAW sessions, remixes, sample packs |
| Mix | One file rendered from everything currently audible, respecting solo, mute and faders. Members only | Karaoke (mute vocals), backing tracks (mute your instrument), acapellas (solo vocals) |
| Loop | Appears when a loop is selected: just that region, as stems or as a mix | Practice clips, drum loops, samples |
#Formats
- MP3 at 320 kbps. Stems are rendered as MP3 by the splitter, so this is the native format.
- HD WAV is a lossless conversion for members. Use it when the stems go into a session or a release.
- Drum elements from drum separation export exactly like stems.
#Apply your changes
An Apply Changes section appears when you have changed something: tick Tempo, Pitch, Volume or Pan to bake the current Studio settings into the download. Leave them off for clean originals; turn them on when you want the slowed-down, transposed practice version as a file. Mix exports always respect solo and mute.
#Free MP3 stem download limits
On the web, MP3 stem downloads are free for the first started project in a rolling 24-hour window. The second shows membership options with an option to continue for free; the third and later require membership. The window counts started projects, not the number of stems or files downloaded. Mix downloads and WAV in any form require membership. Standard splitting and instrument practice stay free throughout.
| Where | MP3 stem downloads without membership |
|---|---|
| Web (studio.soundboost.ai and the free landing pages) | Rolling 24 hours: first started project free; second shows membership options with an option to continue for free; third and later need membership |
| SoundBoost app (iOS and Android) | Rolling 24 hours: first started project free; second and later need membership |
| Vocal Remover - Stem Splitter app | Downloads need a membership |
Members download without limits everywhere, in both formats. Voice Clean projects have their own separate window, so cleaning a recording does not use up your stem downloads.
Can I keep practicing when a download requires membership?
Yes. Download limits affect saving audio files. Standard splits, listening, solo and mute, loops, tempo, pitch, chords, lyrics and the metronome remain free, and you can upload more songs without a daily or monthly quota.
Where do the files go?
On the web, to your browser downloads (a zip when you pick several stems). On mobile, through the share sheet on iOS and into Downloads/SoundBoost on Android.
Are the stems the same sample rate as my upload?
Stems are encoded to 320 kbps MP3; HD WAV is the lossless version of the same render. For mastering-grade stems, upload lossless and use Hi-Fi.
Can guests download?
Yes, MP3 stems only, within the same 24-hour window, tied to the browser that made the split. Log in to keep projects and to lift the limits with a membership.
What file names do I get?
A single stem downloads as "Project - Vocals.mp3"; several stems come as "Project - Stems (MP3).zip".
