What is Bpmkeyfinder ?
BPMKeyFinder is a privacy-first browser-based BPM and key analysis tool that allows users to upload local audio files and perform tempo (BPM), key, Camelot coding, and confidence score detection locally on their device without the need to upload to the cloud or wait in line. It uses Essentia.js (the WebAssembly version of the MTG music information retrieval toolkit) for professional audio analysis, providing practical regularized results from 60 to 180 BPM while retaining original estimates. It is suitable for touring DJs, producers, editors, educators, and choreographers for pre-performance library preparation, harmony mixing planning, sampling alignment, and course arrangement. The professional version supports unlimited analysis, batch uploads, CSV export, and history, helping to establish an efficient library workflow.

FAQ from Bpmkeyfinder
What is BPMKeyFinder? Who is it for?
BPMKeyFinder is a browser-based BPM/key/Camelot analysis tool designed for touring DJs, club DJs, producers, editors, educators, and choreographers to quickly obtain reliable tempo and harmony data.
How accurate is the analyzer?
The tool leverages Essentia.js for audio analysis, cross-checking tempo estimates and providing regularized outputs; for complex mixes, it is advisable to combine confidence score evaluations with auditory review.
Will my audio files be uploaded to a server?
No. All analyses run completely in the local browser; your tracks do not leave the device and are not uploaded, stored, or queued for processing.
What audio formats and durations are supported?
Common formats such as MP3, WAV, FLAC, AIFF, AAC, OGG are supported; track duration is mainly limited by device memory, with typical computers being able to analyze mixes of 20–30 minutes easily.
Can I analyze YouTube or streaming links?
Currently not supported. To protect privacy, BPMKeyFinder only supports local audio files and does not directly process streaming or YouTube links.
Can the analysis results be shared with others? Will it leak audio?
Yes, they can be shared. The links generated by the system contain only metadata such as BPM, key, Camelot, etc., and do not include audio files, so the original track will not be leaked, but the recipient can view the analysis data.
