SCOPE
Free Oscilloscope Plugin for Mac and Windows
A beat-synced oscilloscope built on the same rendering engine as DeltaScope. See your signal: cleanly, accurately, in real time. Zero latency. Free to keep.

Hold the waveform while the audio keeps playing, then zoom into a transient and pan across it at your own pace.

Nothing added to your audio path, drop it on any track and monitor in real time while you mix.
Overview
See the signal
Scope gives you a clear, accurate view of your signal in real time. Beat-synced or free-running, sharp at any size. Zero latency. Minimal CPU. If you find yourself wanting to compare two signals, isolate a frequency band, or measure a waveform, DeltaScope adds those capabilities.
- Beat-sync with 22 divisions, from 1/128th note to 16 bars
- Free-run mode in ms, Hz or note: dial C0 to C8 and hold one, two or four cycles
- Freeze the waveform, then zoom and pan to study it
- Channel modes: Left, Right, Mono, Stereo
- Colour by Frequency tints the waveform by what it contains: bass red, mids green, highs blue
- Polarity-aware clip indicators, a waveform overlay and scope-border markers
- Manual sample or ms offset with a lock, to line the waveform up with the grid
- Adjustable phosphor-style glow, saved with your session
- Export the display as a PNG, and save or share your settings
Beat-synced visualisation
Lock your waveform to the tempo for repeatable, stable views.
22 beat divisions from 1/128th note to 16 bars: straight, dotted, and triplet. PPQ-snap locks transients to the same position every cycle. Free-run mode available for ms, Hz and note-based time windows. If upstream latency shifts your timing, a manual sample or ms offset nudges the waveform back onto the grid and locks once you have it set.
Tempo-locked
Your waveform stays locked to the beat, every division from 1/128th note to 16 bars.
Stable views
PPQ-snap locks transients to the same position every cycle, no jitter, no drift.
Free-run mode
Switch to ms, Hz or note-based windows when you don't need tempo sync. Dial a note from C0 to C8 and the window holds one, two or four cycles of it.
Amplitude scaling
Scale the display from -36 dB to +36 dB to focus on the detail that matters.
Clean, accurate display
Full visual quality from the DeltaScope rendering engine.
Custom waveform colours, or Colour by Frequency, which tints the trace by what it contains. Adjustable phosphor-style glow. Polarity-aware clip indicators. Resize the window to any size, the display stays sharp and responsive, up to 4K.
Colours and glow
Set your waveform colour to match your workflow, and dial in CRT-style phosphor glow from clean to full. Both are saved with your session.
Colour by Frequency
Tint the waveform by what it contains: bass reads red, mids green, highs blue, and a kick under hats shows both at once, so you can see where in the spectrum each part of the waveform lives. Toggle it in the settings cog.
Clip indicators
A clip overlay marks overs on the waveform, and clip markers light the scope border, polarity-aware, top for positive and bottom for negative. Toggle either in the settings cog.
Channel modes
Left, Right, Mono, or Stereo, switch instantly.
Freeze, zoom, pan
Hold the picture, then look as closely as you like.
Freeze holds the waveform on screen while the audio keeps playing. Scroll to zoom into a transient, drag to pan along it, double-click to come back out. Previously DeltaScope features, now in the free Scope.
Freeze holds the picture
One click and the trace stays put while playback carries on. Click again to let it run.
Scroll to zoom
Zoom in up to 64 times around the point under your pointer, so a single kick fills the display.
Drag to pan
Move along the frozen waveform at your own pace. Double-click resets to the full view.
Study it
Catch the shape of a transient, the length of a tail, the moment two sounds overlap, without chasing them.
Support
Zero fluff (no-nonsense)
Compatibility
VST3, AU, AAX and CLAP on macOS 13 Ventura or later, Intel and Apple Silicon native. VST3, AAX and CLAP on Windows 10 or later, 64-bit. One licence key covers both.
No strings
Free to keep. No trial, nothing locked; DeltaScope is a separate plugin, not an unlock. Activate with a free licence key, no dongle, no iLok.
Support
Direct email support. Feature requests welcome.
Works in
Ableton Live, Logic Pro, Pro Tools, Cubase, Bitwig Studio, REAPER, FL Studio, and any other host that takes VST3, AU, AAX or CLAP.

Need deeper analysis?
Scope shows the signal. DeltaScope analyses it.
DeltaScope is our audio analyser plugin, built on the same engine: null test any two signals, isolate and hear the difference, map phase correlation across time, and measure straight from the waveform.
