Auto Tune Wav Files
The key and BPM values in the database are provided by Spotify who use their own estimation algorithms to find key and BPM. The analysis results you get from uploading audio files to this page come from different algorithms that are run on Tunebat servers. Due to the algorithms being different, sometimes the results are different. Also, it's possible that there are differences between the file you upload, and the file Spotify analyzes for a specific song.
How accurate is the finder?
The results you see on this page are estimates. The accuracy of these estimates has been measured across multiple large data sets and compared to several prominent commercial key and BPM detection algorithms. For some datasets this finder proved more accurate than existing commercial key and BPM detection tools. But for other data sets this finder was less accurate. Overall you can expect results from this finder to be as accurate as key and BPM finders found in other commercial softwares, more or less.
What happens to the audio files I upload?
They are uploaded to Tunebat's analysis server where they are analyzed using audio processing algorithms. These algorithms output key and BPM which is reported back to you. Then the audio file is deleted from the Tunebat server. No audio files are kept by Tunebat longer than they are needed to complete the analysis.
What file types can I upload?
MP3, WAV, FLAC, AAC, OGG, and M4A.
