AUDIO TOOLS / ANALYSIS STUDIO
Audio Phase Analyzer
See the relationship between left and right channels, catch mono cancellation, and understand stereo width — without uploading your audio.
Choose your source
Use a file for full-track analysis, or a mic for live monitoring.
Uses permission-based microphone capture. Input is analyzed locally and never recorded or played through your speakers.
A mono microphone shows identical channels and near +1 correlation; true stereo input requires a stereo microphone or interface exposed as two channels by your browser.
No audio loaded. Your files never leave this tab.
Phase intelligence
Load a file or start a microphone to see measurements.
Measurements appear after analysis or while an input is active.

Vectorscope and phase correlation over time.
Vertical = mono (Mid). Horizontal = opposing channels (Side). Dense areas indicate frequently occurring signal values.
Full-file scans reveal brief problematic passages. Negative values suggest possible cancellation on mono playback.
Export your findings
Share measurements, not your source audio.
Full-file scan reports are available after successful analysis. Live microphone data is not saved.
Frequently asked questions
Why does a very wide mix sometimes lose volume in mono?
When channels differ in polarity or timing, averaging left and right can cancel some content. Mono level change estimates the loss from that arithmetic mean.
Does width percentage mean my mix is good or bad?
No. It measures the proportion of energy in the Side signal compared with Mid plus Side. Different productions and instruments call for different balances.
Will the analyzer upload or modify my file?
No. It reads and analyzes the file locally; listening modes modify only the preview signal. Exports contain measured values or a vectorscope image.
Why is microphone input unavailable?
The browser needs a secure context and explicit microphone permission. A mono microphone cannot reveal independent stereo channels.
