SpectroMark v2.0.0

SpectroMark 2.0 — Sync mode

A second mode for lining up many takes of the same piece.

New: Sync mode

• Open many clips as lanes, drag lanes to rough-align, play the auto-normalised mix.
• Ctrl+click one marker per lane: they snap to the robust centre of the group, recomputed on every click. Ctrl+click a synced marker to re-open its group.
• Ctrl+drag a box over several lanes for batch sync (1st markers form group 1, 2nd form group 2, ...).
• Drag a cyan marker to move its whole group earlier or later in time. Alt+click removes a sync point.
• Pitch-preserving stretch between sync points (SoundTouch) with Balanced / Tonal / Transient / Smooth presets.
• Export 24-bit synced WAVs plus a MIX file.
• Sessions saved as .spectrosync.json (Ctrl+S / Ctrl+Shift+S) including zoom, playhead, lane height and window placement. Older session files still load.
• Navigator strip, Page/Scroll playhead follow modes, lane selection, hold Shift to solo the selected lane, Ctrl+wheel lane height.
• M adds a marker to the selected lane; Delete removes the hovered marker; markers are written into the WAVs on save.

Marker mode

• AutoMark: detects word starts, consonants and pitch changes (replaces existing markers, breath rejection).
• Pitch-preserving playback speed 1.0x–2.0x.
• Click selects a marker; drag moves it. Undo/redo, multi-file panel, unsaved-change stars.

Both modes

• Space stops and returns the playhead to where playback started. Enter pauses in place.
• Full dark theme, glowing playhead, markers fade as you zoom out.
• Rebuilt low-latency WASAPI playback engine.

SpectroMark v1.3.0

• New Speed slider in the toolbar: play back from 1.0x up to 2.0x in 0.1 steps with pitch preserved (SoundTouch time-stretch, tuned for natural-sounding voices). Markers still land at the true position in the file.

SpectroMark v1.2.1

• Markers can now be moved by simply clicking and dragging them with the left mouse button (right-drag still works too). Clicking elsewhere still scrubs.

SpectroMark v1.2.0

• Spectrogram frequency axis now matches Adobe Audition's logarithmic display: the curve was measured from Audition and reproduced, so the low end is compressed and the 500 Hz to 15 kHz range is spread the same way.

SpectroMark v1.1.0

• New app icon and project logo.
