Audio Delta Lab
Align two audio files and measure where they differ. Detect timing, gain, polarity, channel mapping, drift, and residual level.
What this tool tells you
What it does
Use this when you want to understand whether two versions of audio differ and where those differences begin.
How to use it
Add the two files, then let TrueRes align them before reviewing timing offset, gain, polarity, channel mapping, drift, and the residual signal.
How to interpret it
Alignment makes comparisons more meaningful, but it cannot erase every format, edit, or decode difference. The residual is the remaining difference after the selected alignment and gain adjustments.
Selected files are processed locally in the browser and are not uploaded to TrueRes for processing. Open this page in a modern browser to use the interactive tool.
