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...
Until now.
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.

The Ericsson Alex documentation system is a paradigmatic example of domain-specific technical communication. It successfully transforms a potentially chaotic information space—thousands of parameters, hundreds of features, dozens of product variants—into a navigable, actionable knowledge base. While not without usability flaws, Alex’s structured approach has directly reduced network downtime and enabled higher levels of automation. As telecom embraces AI and intent-driven management, Alex’s evolution will likely serve as a blueprint for how industrial documentation must adapt: from static text to a fluid, machine-and-human-readable knowledge plane.
