Check your track before you release it.
Drop in a master. In a few seconds you get what Spotify, Apple Music, YouTube and Tidal will do to its volume, whether it clips, whether it falls apart on a phone speaker, and a private link to send it to someone.
What you get
Integrated loudness in LUFS, and exactly how many dB each service will turn it up or down.
Inter-sample peaks that distort after MP3/AAC encoding, and samples stuck at full scale.
Stereo correlation — catches flipped channels and wide mixes that vanish on phones and Bluetooth speakers.
Silence at the start or end, tracks under 30 s, lossy or low-sample-rate sources distributors reject.
An unlisted page with a waveform player and the report. Send it to a collaborator, a mastering engineer, or a label.
Your original file is deleted right after analysis. Only a 128 kbps preview is kept, for 30 days, and you can delete it any time.
Fine print
Measurements follow ITU-R BS.1770 / EBU R128 as implemented by FFmpeg. Platform targets are the ones each service publishes; they change their behavior occasionally, and user settings can override them. Share links are unguessable but not password-protected — don't upload anything you can't let a stranger hear. Upload only audio you have the right to share.
