Precision waveform item editor for REAPER - a native C++ extension that gives you a detailed, dockable waveform view for any media item. Click an item in REAPER's arrange view, and SneakPeak instantly shows you a full-featured waveform editor with dynamics processing, volume envelope editing, spectral analysis and repair, game-audio tools (seamless loop authoring, one-shot batch export, true-peak limiting), multi-item layering, real-time metering, and full interface scaling (80-200%). Available for macOS (arm64/x86_64), Windows (x64), and Linux (x86_64/aarch64).
Select any audio item in REAPER and get an instant, detailed waveform with dynamics processing, volume envelope editing, spectral analysis, multi-item layering, and real-time metering - all in a dockable window.
The gate taming breaths between dialogue phrases (v2.2) - threshold/gate lines, envelope automation and detector curves drawn live on the waveform.
The Dynamics panel (compressor tab) and the Settings panel - UI scale 80-200%, density presets, view preferences.
Spectral view - async FFT spectrogram with frequency band selection.

REAPER is the most powerful DAW on the market, but a detailed waveform item editor has always been the one thing missing. SneakPeak fills that gap - a dedicated editor that lives inside REAPER as a native extension.
I looked everywhere for a solution - scripts, extensions, workarounds - but nothing delivered what I needed. So I built it. After months of development, I'm releasing SneakPeak as a free, open-source extension for the REAPER community. I considered making it paid, but ultimately decided that the community deserves access to tools like this without barriers.
If you find SneakPeak valuable, please consider supporting its development. Every contribution helps keep this project alive and growing.
SneakPeak has five viewing modes: ITEM (default - click any item), Timeline View (after cutting), Multi-Item (select 2+ items), SET (working set, press T), and Standalone (drag & drop files). All non-destructive editing goes through the REAPER API with full undo.
- Global UI scale (80-200%) - the entire interface scales from one slider: fonts, toolbar, ruler, meters, panels, and every click target. First run auto-detects your system DPI (Windows display scaling, Linux GDK scale).
- Settings panel - gear icon in the mode bar: UI scale with live preview, density presets (Compact / Comfortable / Spacious), Fit to Window, and the Ruler / Meters / View preferences - including hide-ruler and the Detailed/Simple waveform style (new in v2.4).
- Premium rendering - anti-aliased, DPI-crisp Dynamics panel, Settings panel, gain knob, L/R meters and toasts.
- Precision waveform rendering - Peak + RMS display with dB scale and zero-crossing line.
- Waveform style: Detailed / Simple (new in v2.4) - Detailed keeps the darker RMS band inside the peak waveform; Simple draws single-colour peaks only. Clip marking is drawn in both styles.
- Truthful clip display - red marks real clipping (source flat-tops, or over-0dB in destructive Standalone mode); amber marks over-0dB warnings in REAPER's float contexts where nothing has clipped yet. A dark-red 0dB reference line appears when zoomed out vertically.
- Deep zoom - Horizontal and vertical zoom with scroll wheel, toolbar buttons, and keyboard. Zoom to fit, zoom to selection. Zoom anchors on the mouse position or the edit cursor (Settings > View).
- Minimap - Resizable overview bar showing the full item waveform. Click to navigate, drag to scroll.
- Time ruler - Dynamic tick intervals from milliseconds to minutes with position readout.
- Channel solo (L/R) - per-channel monitoring that keeps the soloed channel on its own side (take pan balance under the hood; your pan is saved and restored).
- Precision selection - Click and drag to select audio regions. Shift+click to extend. Double-click to select all.
- Cut / Copy / Paste - Full clipboard support with sample-accurate editing.
- Normalize - Peak normalization to 0 dB, plus LUFS normalization (-14 / -16 LUFS).
- Fades - Drag fade handles with continuous curvature control (horizontal = length, vertical = curve shape). 7 base shapes with smooth curvature matching REAPER's native D_FADEINDIR. Scroll on a handle to nudge the length (Cmd = 1 ms steps), Shift+drag for a 1/4-speed fine trim (new in v2.4).
- Slip content (new in v2.4) - Alt+drag outside the selection in ITEM mode slides the take's source under the item (live arrange update, source-bound clamp, one undo point per slip).
- Reverse - Reverse selection or full item.
- Gain adjustment - Interactive gain knob (+24 to -60 dB) with fine-adjust mode (Cmd+drag). Scroll wheel on knob for +/-0.5 dB. Quick +3/-3 dB from context menu.
- DC offset removal - One-click DC bias correction.
- Silence / Insert silence - Zero out selection or insert silence at cursor.
- Snap to zero-crossing - Intelligent selection boundaries at zero-crossing points.
- Undo / Redo - Full REAPER undo integration, with redo (Ctrl+Shift+Z / Ctrl+Y, new in v2.4). Independent 20-level undo + redo stacks in standalone mode; bounded edits snapshot only the touched range, so long files stay light.
- Bindable toolbar actions (new in v2.4) - every toolbar command is a named REAPER action: assign any shortcut in the Action List.
Right-click > Process > Dynamics Panel. SneakPeak auto-activates the take volume envelope if it isn't already enabled (no manual setup). Analyzes audio and writes volume envelope automation - zero CPU cost during playback. In Standalone mode (new in v2.4) the same panel applies destructively instead - the gain curve (comp + gate + de-ess) is multiplied into the audio with one undo step, completing the standalone podcast chain (Dynamics > Hard Limiter > Save).
- Built-in compressor - Industry-standard gain-smoothing architecture (ratio, threshold, soft knee, attack, release, auto makeup gain). Matches FabFilter Pro-C / Waves / ReaComp.
- Upward compression + BOTH mode (new in v2.4) - a DOWN/UP/BOTH switch: lift quiet material toward the threshold (with an M.Boost cap and a gate-coupled floor), or run the single-pass leveler that tames loud and lifts quiet at once, with the knee acting as a leave-alone band.
- Extended ratio (new in v2.4) - 1:1 through Inf:1 (true limiting, with a detent) and into over-compression (negative ratios).
- Noise gate - a full downward expander (reworked in v2.4): ratio 1-10:1, hysteresis band against chatter, exposed attack/release, floors down to -90 dB threshold / -80 dB range, an Off detent.
- Wideband de-esser (new in v2.4) - DE-ESS tab with a band-pass / high-pass detector driving a third gain-reduction stage, a hard reduction cap, and a LISTEN lane that paints every span the de-esser bites.
- Per-stage bypass (new in v2.4) - power dots on the COMP and GATE tabs audition each stage in real time, alongside the whole-chain A/B.
- Lookahead - 0-20ms transient detection without latency cost.
- Tabbed control panel - anti-aliased COMP / GATE / DE-ESS / View tabs with knobs, transfer plot and GR meter; every change updates the curves on the waveform in real time, and double-clicking a knob lets you type an exact value.
- Live mode - Real-time envelope writing as you drag knobs. Waveform updates instantly, no Apply needed.
- 8 built-in presets - Default, Gentle Leveling, Voice/Podcast, Broadcast, De-breath, Music Bus, Upward Leveling, De-Ess Vocal.
- Per-item persistence - Settings auto-saved via P_EXT, auto-loaded when reopening.
- GR meter + shading - Gain reduction visualization in panel and on waveform.
- A/B bypass - Instant before/after comparison (audio + visual).
