Mix Analyzer

What is a mix analyzer?

A mix analyzer reads your audio file and measures the key technical parameters that determine whether your mix will translate well across playback systems and streaming platforms. Our free mix analyzer checks loudness (LUFS), true peak (dBTP), stereo width, phase correlation, and frequency balance across five bands — giving you a comprehensive overview of your mix's health in 30 seconds. No signup, no download, no plugin installation required. Just upload your file and get instant results.

What a mix analysis tells you

A proper mix analysis covers several dimensions that work together to determine how your track sounds:

• Loudness (LUFS): Whether your track meets streaming platform targets (−14 LUFS for Spotify/YouTube, −16 for Apple Music).
• True Peak (dBTP): Whether inter-sample peaks exceed the −1 dBTP safe limit, preventing clipping on playback.
• Stereo Width: How wide your stereo image is, and whether it's too narrow (mono-ish) or too wide (phase issues).
• Phase Correlation: Whether your left and right channels are in phase — critical for mono compatibility on phone speakers and club systems.
• Frequency Balance: Whether your mix has too much or too little energy in sub-bass, bass, mids, high-mids, or highs.

Why you should test your mix before release

Mixing on monitors in a treated room gives you one perspective — but your listeners will hear your track on phone speakers, earbuds, car stereos, club systems, and Bluetooth speakers, each of which reveals different problems. A mix analysis catches issues you might miss: excessive low-end that sounds fine on your sub but muddy everywhere else, phase cancellation that makes your bass disappear in mono, or a true peak that clips on certain DACs. Testing your mix with an analyzer before release is the cheapest insurance you can get — it takes 30 seconds and costs nothing.

How to use this mix tester

Upload your final mix bounce (WAV, MP3, FLAC, M4A, or AIFF, up to 50MB). The analyzer reads the file and reports each metric with a color-coded rating: green means good, amber means borderline, red means you should fix it before release. Each metric includes an interpretation and recommendation. For a deeper dive with severity-graded fixes and specific EQ/compression suggestions, get the full analysis at mixdiagnose.com.

Common mix problems an analyzer catches

The most common issues we see are: tracks mastered too loud (above −10 LUFS, which get turned down by streaming platforms), true peak overshoots (no true peak limiter on the master bus), excessive low-end buildup (too much sub-bass energy relative to mids), and stereo width issues (too wide with poor phase correlation, or too narrow). A 30-second mix analysis catches all of these before you release — saving you from re-uploading, re-mastering, or living with a mix that doesn't translate.
