Problem
Musicians and producers often lack accessible, web‑based tools for quickly analyzing tracks, separating stems, mastering audio, and creating visual content, forcing them to rely on multiple desktop applications or expensive software suites.
Solution
Key & BPM offers an online platform that consolidates essential audio utilities into a single cloud service. Users can upload any track to automatically detect its key and BPM, separate vocals, drums, bass, or other instruments using AI‑driven source separation, and apply reference‑based mastering to match professional sound quality. The suite also includes practical tools such as a BPM tapper, web metronome, key/tempo changer, and a music video maker that generates visualizers in minutes. All processing occurs in the cloud, eliminating the need for local installations and enabling fast results on any device. A searchable database of over 70 million songs provides harmonic data and recommendations to aid remixing, DJing, and songwriting. The platform operates on a freemium model, with a Pro subscription unlocking higher‑quality outputs, longer file limits, and priority processing.
