What tempo and key?
Tunebat
Estimate tempo and key to compare versions, plan vocals, or start a remix.
Basic analysis works without signing in and processes audio in your browser. Mood metrics, saved results, and report downloads are paid features.
How to use it
Select an audio file and wait for the BPM and key results. Write down the values if needed.
Estimates can be wrong, including half- or double-tempo readings. Check them against the song.

Loudness Penalty
Estimate playback level adjustments on Spotify, YouTube, and other services, then compare the sound.
Basic analysis needs no account or email and does not upload audio. Skip the optional email report and paid plug-in.
How to use it
Choose an MP3 or WAV, check each platform’s dB adjustment, then preview the adjusted playback.
A negative value is not a quality score or mastering target. Listen before deciding to change anything.
