Transcoded from lossy sources. Detected from the audio — not the tags.

Bought as WAV. Still fake.

Verify your masters

Full-file analysis. One verdict.

  • Integrated loudness (LUFS) — EBU R128
  • True peak measurement (dBFS)
  • Clipping detection + dynamic range
  • Phase correlation — will it collapse on mono PA?
  • Spectral ceiling — where does the audio actually end?
  • Bit-depth verification — is your 24-bit file really 24-bit?
