StereoWeak signal
Phase coherence
Whether the two channels of a stereo file relate to each other in a physically plausible way.
Phase relationships encode a great deal about how audio was captured — a pair of microphones at a distance produces predictable inter-channel delays. Reconstructed or synthesised audio does not necessarily obey those constraints.
In practice this is a weak signal for detection, because the vast majority of released music is not a raw microphone capture. Multitrack production, virtual instruments and stereo effects break the physical assumptions long before any AI is involved.
How this tool uses it
Observed only indirectly through mid/side behaviour. No standalone phase claim appears in the report.
What else produces the same reading
- Virtually all modern multitrack production.
- Software instruments and synthesised sources.
- Reverb and delay plug-ins.
