What's new in 1.9.6

  • Waveform overview — an optional waveform strip above the spectrogram for quick navigation of the file's amplitude envelope.
  • Harmonic cursor — overlays overtone guides on the hover cursor so you can line up a fundamental with its harmonics.
  • Measure region — drag to select a rectangle and read out Δ time, Δ frequency, the musical interval and 1/Δt rate, plus the region's peak frequency/level, RMS, peak, true peak, and integrated loudness (LUFS).
  • Spectrum slice — double-click a time point to open a frequency-vs-level slice for that instant.
  • Updated localizations across all supported languages.
