Hi-Res Audio Verifier
Inspect source metadata and spectral evidence for possible upsampling or lossy ancestry. Results are heuristic, not proof of provenance.
What this tool tells you
What it does
Use this when you want to inspect whether a high-resolution file contains signal evidence consistent with its reported format. TrueRes separates container claims from decoded-signal evidence.
How to use it
Drop one file for deep analysis, or add a collection for a header-first audit and deep-analyze selected tracks.
How to interpret it
The evidence score combines effective bit-depth estimates, bandwidth behavior, possible lossy-ancestry signatures, and dynamic-range information. It is not a probability, certification, or proof of provenance.
Frequently Asked Questions
- How does the Hi-Res Audio Verifier work?
- It combines reported metadata, an effective bit-depth estimate, bandwidth evidence, possible lossy-ancestry signatures, and dynamic-range information into a heuristic composite. It reports evidence, not proof of a file’s provenance.
- What file formats are supported?
- WAV, FLAC, AIFF, MP3, OGG, AAC, and M4A files are supported. For best results, test lossless files (WAV, FLAC, AIFF).
- Is my file uploaded to a server?
- Selected files are processed locally in the browser and are not uploaded to TrueRes for processing.
