Actionable checks
The report turns measurements into plain-language passes, notices, and warnings instead of presenting a wall of unexplained numbers.
MIX CHECKER
Run a private mix quality check
Catch technical warning signs before release. Review clipping, peak headroom, average level, dynamics, stereo phase, silence, and DC offset without uploading your mix.
USE THE TOOL
Upload your mix for a technical preflight
Use the same rendered file you plan to distribute. WAV is best for final checks.
Private by design · 1 creditGoogle sign-in is required, but your audio is analyzed in this browser and never uploaded.
WHY USE THIS TOOL
Useful answers without hiding the uncertainty
Stereo and dynamics included
Review correlation, peak-to-average crest factor, level range, clipping, and headroom from one local pass.
No upload risk
Unreleased music remains on your device. Nothing is stored, transmitted to AWS, or sent to a third-party analyzer.
HOW IT WORKS
From input to answer
- 01
Export the real delivery mix
Analyze the same sample rate, bit depth, and limiter output you intend to upload to the distributor.
- 02
Review warnings in context
Clipping, very low crest factor, negative stereo correlation, or DC offset deserve investigation, but every genre has different norms.
- 03
Verify on meters and speakers
Use a calibrated LUFS meter, mono check, headphones, and several playback systems before making final mastering decisions.
QUESTIONS, ANSWERED
Frequently asked questions
Does this replace a mastering engineer?
No. It is a technical preflight that can flag measurable risks, not an artistic or release-ready mastering verdict.
Is average level the same as LUFS?
No. This page reports decoded RMS level in dBFS. It does not label that measurement as gated, K-weighted LUFS.
What stereo correlation is risky?
Sustained negative correlation can indicate cancellation in mono. Brief negative moments may be intentional, so listen and inspect a dedicated phase meter.
