SpectroFlac 1.1.0 — interactive spectrogram, per-channel spectra and stereo analysis.

New

  • Interactive spectrogram: pinch to zoom (horizontal = time, vertical = frequency, diagonal = both), drag to pan, double-tap to zoom, a frequency/time/level cursor, Mid / Left / Right / Side views and a measured-cutoff overlay.
  • Spectrum chart with per-channel peak-hold and average curves.
  • Stereo analysis: left/right correlation (with a timeline), balance, width, out-of-phase passages, silent-channel and near-mono detection.
  • Joint-stereo artifact detection (supporting evidence only; never changes the verdict by itself).
  • Encoder fingerprints rebuilt from measured MP3 (CBR/VBR), AAC, Vorbis and Opus round trips.
  • Stereo values added to the text, CSV and JSON exports.

Important: this release is signed with a NEW key. Android will not update an existing 1.0.0 install over it — uninstall 1.0.0 first (the local history is not kept).

Limits: very high bitrate encodes (AAC 256+, LAME V0, Vorbis q6+) leave no spectral cut and cannot be detected; fingerprints were calibrated on synthetic noise through FFmpeg encoders.
