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.

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.
REFERENCE
What this tool returns, and where it stops
Technical meters
Peak level (dBFS), average level (RMS), crest factor, level range, clipping percentage, silence share, DC offset and stereo correlation.
Plain-language findings
Each check is marked pass, notice or warning, for example “Clipping detected”, “Very little peak headroom” or “Possible phase conflict”, with a suggested next step.
Input, handling and cost
- Input
- An audio file chosen from your device
- File handling
- Not uploaded; analysis runs locally in your browser
- Cost
- 1 credit. The file is decoded in your browser and is not uploaded.
Known limitations
- It measures the decoded file. It is not a replacement for a loudness-standard meter or a calibrated listening room.
- Clipping is counted where samples reach digital full scale; inter-sample peaks after lossy encoding are not simulated.
- A negative stereo correlation flags a possible phase problem, but some wide stereo effects are intentional.
- Thresholds are general rules of thumb, not delivery requirements for any specific platform.
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.
