occularScope offers a clear, beat-synced view of your audio waveforms, letting you see how sounds move in real time. You can overlay a sidechain signal, freeze the view, and switch between line or filled displays to compare channels with precision.

It includes stereo and mono modes, manual or automatic gain, and delay correction for waveform alignment. The interface can be fully resized and customized with color themes, supporting both dark and light setups on Windows, macOS, and Linux systems.

Oscarizor offers clear and detailed real-time audio visualization for mixing, mastering, and sound design. It shows 2D and 3D views of your tracks, allowing comparison of up to 10 channels at once. Color customization, zooming, and adjustable display settings help make frequencies and waveforms easy to understand.

This plugin supports spectrum and waveform analysis, stereo and phase monitoring, and synchronization with your DAW. Its tools help identify frequency balance, phase issues, and loudness levels across multiple tracks. Oscarizor is available for Windows and macOS in VST, AU, and AAX formats.

MOscilloscope offers a clear view of your audio in real time, helping you see the shape, pitch, and movement of sounds as you work. It includes features like zoom, normalization, and pause controls, making it easy to study waveforms and sonic details.

You can use MOscilloscope as a waveform display, spectrum analyzer, or sonogram generator. It supports stereo, mid/side, and surround views, giving you a flexible way to check phase alignment and tonal balance. It’s a free tool available for both Windows and Mac.

s(M)exoscope offers a clear way to view and study your audio signals in real time. It shows detailed waveforms, helping you understand timing, frequency, and signal behavior. Designed for accuracy and speed, it keeps the original plugin’s look while working smoothly on modern systems.

You can adjust timing, amplitude, trigger speed, and sync options to analyze sounds more closely. Useful for mixing, sound design, and learning synthesis, s(M)exoscope makes it easier to see how changes affect your audio. It supports both Windows and macOS in VST and AU formats.

Signalizer offers real-time audio visualization with smooth 3D graphics that help you clearly see the shape, balance, and detail of your sound. It combines an oscilloscope, spectrum analyzer, and phase scope into one flexible tool for easy monitoring during music production.

With adjustable views, zoom, and color settings, Signalizer lets you customize how your audio looks as it plays. Its precise visual feedback helps you track tone, stereo image, and rhythm across any mix, giving clear insight into your sound’s behavior.

J-Scope Oscilloscope offers a clear visual view of your audio signals inside your DAW. It works like a traditional hardware scope, making it easy to study both fast and slow waveform changes. The adjustable phosphor decay lets you track fine details in dynamics and modulation.

It supports stereo input with multiple display modes, such as left/right split, sum, difference, and X/Y plots. With tools for trigger control, time and gain adjustments, freeze display, and precise waveform measurements, J-Scope helps producers and developers inspect sound with clarity and precision.

Open Scope offers a clear way to see sound in motion. It works as an oscilloscope, spectrum analyzer, and signal generator, showing both time and frequency views. With real-time visuals, it helps users understand how their audio behaves as it passes through each stage.

Useful controls like Gain, Atten, and Time let you adjust the view and signal strength to study your mix more closely. Open Scope’s simple layout makes it easy to track left and right levels, view frequencies, and spot changes while shaping sound in your projects.

Oscilloscope offers a clear view of your stereo audio signals, letting you see how sound moves and changes over time. It displays left and right channel waveforms side by side, helping you check balance, phase, and timing in your mixes or sound design work.

You can adjust trigger levels, zoom in for detail, and shift each channel’s offset to line them up accurately. With simple controls for edge triggers and channel selection, Oscilloscope makes signal monitoring quick and visual during recording, mixing, or troubleshooting sessions.

Signal Analyzer offers a clear way to view and measure audio signals in real time. It combines an oscilloscope and a spectrum analyzer, letting you see sound both as a waveform and as frequency data. You can pause the display, zoom in, and even export images for reference.

This plugin helps you spot level issues, frequency peaks, or unwanted noise. The oscilloscope can sync to the input signal for stable visuals, and it supports high spectral resolution up to 32,768 bands. Signal Analyzer works in most major DAWs on Windows in 32-bit VST format.

VS-1 offers a classic analog feel in a digital form, combining three oscillators, two filters, four envelopes, and four LFOs for flexible sound shaping. Its X/Y oscilloscope display gives real-time visual feedback, linking sound movement to the retro look of 1960s–1980s hardware.

The built-in effects, including phaser, delay, EQ, and unison, help add depth and character to patches. With both mono and poly modes, VS-1 is well suited for smooth pads, vintage strings, or expressive leads with an old-school tone that fits modern mixes.
