We all hate sudden changes in loudness - they're the #1 source of user complaints.
To avoid this and save us from being "blasted" unexpectedly, online streaming services measure loudness, and turn down music recorded at higher levels. We call this reduction the "Loudness Penalty" - the higher the level your music is mastered at, the bigger the penalty could be. But all the streaming services achieve this in different ways, and give different values, which makes it really hard to know how big the Loudness Penalty will be for your music...
Simply select any WAV, MP3 or AAC file above, and within seconds we'll provide you with an accurate measurement of the Loudness Penalty for your music on four of the most popular music streaming services, plus a "ballpark" estimate for Apple Sound Check, which is used by Apple's radio streaming service.

We call this level reduction the "Loudness Penalty" - the lower the LP numbers, the more your music will be turned down to match other songs.
For example, a Loudness Penalty of -2.4 on YouTube means your song will be played back 2.4 dB quieter than its original loudness.
Each streaming service chooses their own method of measuring loudness, and how loud the loudest songs should be played (the reference level). This means there is a slightly different Loudness Penalty for each service.
