About

Browser utilities such as Audio Cutter, MIDI Editor, and BPM Finder run on the user's device, and files are only uploaded when a result is saved. AI tasks use credits that are refunded automatically if a task fails. Outputs can be passed straight to the next tool, such as trimming a clip and sending it to the stem splitter, without downloading and re-uploading.

Key Features

Generate songs from a text description or your own lyrics
Split songs into vocal and instrumental stems with AI
Convert audio recordings into editable MIDI notes
Detect tempo, key, and chords from any audio file
Trim clips in the browser and export audio to sheet music

Use Cases

Trim a clip for a video, podcast, or stream with Audio Cutter, then build a backing track with the AI Music Generator
Mute vocals with the AI Stem Splitter and read tempo and chords with BPM Finder and Chord Finder to learn a song by ear
Convert a clear melody to notes with WAV to MIDI, tweak it in MIDI Editor, and draft a readable chart with MIDI to Sheet Music

From the founder

Who it's for

“Music producers, songwriters, and hobbyist musicians who need stems, MIDI, chords or lyrics fast without buying heavy studio software. SampLab Pro runs all twelve tools in the browser.”

About me

“I build small browser-first music tools and wanted the messy part of production, splitting stems and reading chords, to take seconds instead of a studio session. SampLab Pro is that toolbox, free to start with 50 credits plus 10 daily credits at https://samplab.pro/”

FAQ

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.
