Terms

SampLab Pro provides free, browser-based musical utility tools including Audio to MIDI, BPM & Key Finder, Chord Recognition, Stem Splitter (frequency band separation, not vocal, drum, or bass source separation), MIDI to Audio, and Lead Sheet Generator. On the free browser path, Audio to MIDI processing is limited to the first 30 seconds of an audio file.

You retain ownership of your content, but you represent and warrant that you own or have obtained all necessary rights, licenses, and permissions for any audio or MIDI files you import. You are solely responsible for ensuring your source material and its use comply with applicable copyright and intellectual property laws.

All tools, analyses, and generated outputs are provided on an "as-is" and "as-available" basis without warranties of any kind and with no service level agreement (SLA). We make no guarantee of uninterrupted availability, transcription accuracy, or that converted output files are suitable or cleared for commercial use.

SampLab Pro is an independent service with no paid tiers, subscriptions, or payment processors such as Stripe. SampLab Pro is entirely unaffiliated with the discontinued Samplab VST (samplab.com), ByteDance, or seedaud.io. The service is currently offered in English only.
