e vs Scope AUv3 Visualizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
e
This app combines an oscilloscope, FFT analyzer, and signal generator. It allows real-time observation of audio device frequency characteristics and waveform analysis. Features include multiple oscilloscope modes, detailed FFT spectrum analysis, and various signal generation options.
- Oscilloscope with Normal, Trigger, and Single modes
- FFT analyzer with peak level, frequency, and THD display
- Signal generator for sine waves, white noise, and sweeps
- Real-time FFT synchronization sweep mode
- Screen capture and save functionality
- Adjustable sensitivity and time span

Three tools (oscilloscope, FFT analyzer (spectrum analyzer), signal generator) are included in the e-scope 3-in-1. Please take a look at this video. Basic functions: http://youtu.be/WPm4Dbz0WAo Automatic measurement add-on: http://youtu.be/K6_stq_t2zQ It can observe the frequency characteristics of audio devices using an FFT analyzer and a signal generator. Observation of frequency characteristics in real time is possible by using the FFT synchronization sweep mode. inputs are acquired via the built-in microphone or headset connector. -Oscilloscope The oscilloscope has three modes. * Normal mode: It is suited to observe music waveforms. * Trigger mode: This mode is suitable for repeated waveforms such as sine wave. You can observe waveforms in stationary condition. * Single mode: This mode is suitable for observing one-time waveform such as impact sound. You can change the sensitivity and time span by pinch out and pinch in. -FFT analyzer It is possible to analyze the frequency spectrum of an input signal. The peak level and the frequency are displayed at the top of the screen. The display can also be used as a simple frequency counter when you enter a single signal. In addition, the THD (Total Harmonic Distortion) value is displayed at the bottom left of the screen. By pressing the resolution button, you can select the frequency resolution free three types. When you press the peak hold button, the maximum value of the signal that you are currently viewing is displayed in a red line. -Signal generator The signal generator can be used to generate a signal of four types: Sine wave of 1Hz to 20kHz, White noise, Linear sweep and Log sweep ranging from 20Hz to 20KHz. When you tap the area that displays the frequency or sweep time range, a picker will appear. Please set the appropriate numbers in it. By using the mode [optimized for FFT], it can automatically change to a frequency with highest FFT accuracy. Please use the feature if you want to accurately measure the THD. While the frequency is displayed, it will be ignored when you enter 0000. During the FFT synchronization sweep mode, when you enter 000 as the display start time for the sweep time display, the FFT synchronization sweep mode will be activated. It will change the frequency at high speed in FFT analysis unit time (less than 0.1 seconds) . It is possible to observe the frequency characteristic in real time in this mode. When you press the Copy button at any mode, you can capture screen and save it to a camera roll.

Get professional audio visualization with your AUv3 host or the standalone app. Scope transforms your audio into stunning visual displays using GPU-accelerated graphics with classic phosphor glow effects reminiscent of vintage CRT oscilloscopes and more. Featuring Scope Linear, Scope Circular, Flurry particle, Spectrum, Spectrogram, Spectrum Equalizer, 3D Spectrum, Semaphore, Sliding Scope, Loudness and Polar Level visualization modes with single and multi-channel split view, plus an Overlap option that draws both channels on one canvas in Scope Linear. Multiple color schemes (including classic phosphor green, vibrant 80s Red and Rainbow) with smooth transitions. Flurry mode renders mesmerizing smoke-textured particles with audio-reactive dynamics, inspired by the classic screensaver. Loudness is an ITU-R BS.1770 / EBU R128 meter with integrated, short-term and momentary loudness, true peak per channel, loudness range and a three-minute history against streaming, podcast and broadcast targets. Polar Level is a stereo vectorscope that plots pan position against level in dB, shows out-of-phase content in red and includes a correlation meter. All visualization modes are fully automatable parameters in your DAW. Optimized for HiDPI Retina displays with dynamic line width scaling, Scope delivers smooth 60fps+ performance for live performances, creative sound design and professional audio monitoring. Whether you are analyzing dynamics during mixing, assisting with sound synthesis or adding visual interest to your sessions, Scope provides the precision and aesthetic flexibility you need. Place it anywhere in your signal chain to visualize audio at any point, though it is typically used last to analyze the cumulative effects of your processing chain.

Verdict
The clearest difference is rating: Scope AUv3 Visualizer at 4.2 against e's 3.0. Scope AUv3 Visualizer also leads on in-app purchases (none vs 1) and update cadence (every 9 days vs every 8 months). e's advantage is review sentiment (80% vs 67%) and price ($1.99 vs $3.99). On ads, monetization model and device support there is nothing between them.

e costs $1.99 and Scope AUv3 Visualizer $3.99 up front. e sells 1 one-off in-app purchase. Scope AUv3 Visualizer asks for nothing beyond the download.
Scope AUv3 Visualizer holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Scope AUv3 Visualizer has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of e's written reviews are positive against 67% of Scope AUv3 Visualizer's, so the app with the better star average is not the one people write more warmly about.
e ships an update every 8 months, Scope AUv3 Visualizer every 9 days. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
