If the results sound good, you don’t need to take any action. Use them to Preview your music and compare with suitable reference material. Streaming services apply loudness normalization so we don’t have to. 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.įor example, a Loudness Penalty of -2.4 on YouTube means your song will be played back 2.4 dB quieter than its original loudness. Online streaming services measure loudness, and turn down loud music to avoid 'blasting' listeners with sudden changes in loudness. Your file will not be uploaded, meaning this process is secure and anonymous. 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 many of the most popular music streaming services, and allow you to preview how it will sound for easy comparison with your favorite reference material. 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. We call this reduction the 'Loudness Penalty' - the higher the level your music is mastered at, the bigger the penalty could be. To avoid this and save us from being 'blasted' unexpectedly, online streaming services measure loudness, and turn down music recorded at higher levels. We all hate sudden changes in loudness - they're the #1 source of user complaints. Online streaming services are turning down loud songs.
