Frequently asked questions

Which tools need a SampLab Pro account?

Browser tools open without signing in. AI tools need a SampLab Pro account because they use credits and keep results private. Saving to the library also needs an account.

How do credits work in SampLab Pro?

Browser tools do not use credits. AI tasks do: 6 credits for lyrics, 28 credits for a song from your own lyrics or an instrumental, 66 credits for a song from a description alone, 36 credits for stem separation. Credits are charged only when a task succeeds. See Pricing.

Are files uploaded to SampLab Pro?

Browser tools such as Audio Cutter, WAV to MIDI and MIDI Editor process files on the device. Saving a result uploads that result. AI tasks upload the input they need. Details are in Privacy Policy.

What formats and lengths does SampLab Pro accept?

Browser audio tools accept formats the browser can decode, such as MP3, WAV, FLAC, OGG, M4A, AAC or WebM, up to 50 MB and from 1 second to 10 minutes. MIDI files must be .mid or .midi, up to 50 MB, 20,000 notes and 10 minutes. AI Stem Splitter takes common audio from 1 second to 6 minutes and up to 50 MB on Free, and up to 15 minutes and 200 MB on paid plans.

Is the frequency band splitter the same as stem separation?

No. Frequency Band Splitter only filters low, body and high ranges. AI Stem Splitter uses AI for vocal, accompaniment, bass and drum tracks.

Can I use SampLab Pro results commercially?

Check Terms of Service before you publish or sell. You must own or have permission to use what you upload. Results are provided as is, with no guarantee they are cleared for commercial use.

How long are works kept?

Results are private. Saving to the library is separate. Free files are kept for 180 days. Eligible paid memberships keep them longer. You can delete a saved file, or delete the account and saved files in account settings.
