SignalScope X includes a free oscilloscope tool. SignalScope X makes additional tools available via 3 tiers of subscription-based tool sets to meet your basic, advanced, and professional needs. Each subscription works on your iPhone, iPad, and Mac. Features: - Analyze signals coming from the Mac or iOS device’s current audio input device. - Assign engineering units to your input signals and calibrate external transducers for accurate measurements. - Assign input channel units and sensitivities for individual USB Audio devices. - Connect lab-grade microphones and sensors to your Mac, iPad, or iPhone with suitable interface hardware for precise measurements. - SignalScope offers enhanced support for select hardware from Digiducer, The Modal Shop, and miniDSP. - Nominal acoustic sensitivities included for iPhone and iPad built-in microphones, voltage sensitivities for headset input (including the standard Lightning-to-headset adapter). - Manually switch between available audio input and output sources. - Load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT-based measurements. - Manually adjust audio sample rates, even up to 768 kHz, depending on hardware. - Save acquired measurement data to CSV, TXT (tab-delimited), or MAT files. - Save high-resolution analyzer display images to PDF files. - Retrieve your data files from your device via Files (iCloud Drive), iTunes File Sharing, or through a web browser on another device. Files may also be opened in other compatible apps (e.g. Mail, Notes, Numbers, Dropbox, etc). Basic Tools: - Oscilloscope - MultiTool - Powerful data monitoring and project management (Add 2-6 subtools, depending on screen size, and save configurations for easy recall at a later time.) - FFT Analyzer - Spectrum analyzer with user-settable frequency limits and input triggering - 2D Real-time Spectrogram Analyzer - XY Plotter - Create Lissajous curves or visualize your stereo mix - Stereo Signal Generator Advanced Tools: (Advanced Tool Set also includes basic tools) - 3D Real-time Spectrogram Analyzer - Stunning live visualization of incoming data - Octave-band Analyzer - Whole and 1/3-octave RTA - Level Meter - Overall signal level meter - Max Levels - Traffic-light-style monitoring - Noise Dosimeter - Data Recorder - Stream up to 8 channels to WAV, AIF, or CAF audio files - Multi-channel Audio File Player - Analyze pre-recorded data Pro Tools: (Pro Tool Set subscription includes all tools) - Dual-channel System Analyzer (Dual FFT analysis with support for Frequency Response Magnitude/Phase, Phase Delay, Group Delay, Coherence, Impulse Response and Cross-Correlation) - Sound Intensity Analyzer - With a suitable p-p probe, measure sound intensity and acoustic particle velocity spectra (narrowband and whole or 1/3-octave bands) and time waveforms. - Room Acoustics Analyzer (T20, T30, T60, nonlinearity, EDT, Early Decay Time, Center Time, Clarity, and Definition in various frequency bands, adjustable Schroeder integration limits) - Polar Plot - Generate beautiful high-resolution plots of polar data. - STI/PA Analyzer - Direct STI and STIPA measurements Additional Pro Features: - User-defined custom metadata in saved audio and data files - Data logging support in the Level Meter, Octave Analyzer, and Noise Dosimeter - Percentile exceeded sound levels in the Level Meter and Octave Analyzer - NC, RNC, and NR references curves, NC, SIL, and NR values in the Octave Analyzer - Voltage decibel levels can be displayed in dBV or dBu Subscription Terms: - https://www.faberacoustical.com/apps/subscriptions/terms.html Privacy Policy: - https://www.faberacoustical.com/about/privacy.html Terms and Conditions for FaberAcoustical.com: - https://www.faberacoustical.com/about/terms.html ## Rankings - #279,443 — Overall ## Review summary Overall, reviewers praise SignalScope X for professional-grade measurements and cross-device convenience, with a rich feature set. However, frequent complaints focus on subscription-only access for core features, the cost/value gap for legacy buyers, loss of previous licenses, and workflow/UI usability issues that hinder setup management and user experience. ### Pros - Professional-grade measurement with calibrated, trusted results. - Cross-device subscription works across iPhone, iPad, and Mac (single license). - Rich feature set for sound analysis (RTA, FFT, spectrogram, oscilloscope). - Reliable performance and responsiveness—often praised as less buggy than alternatives. - FFT-based analysis is helpful for debugging real-world audio issues (e.g., guitar pedal noise). ### Cons - Subscription gating hides key features (FFT, spectrogram) behind a recurring fee and marketing claims. - Perceived high price and ongoing subscription costs after paying upfront, viewed as overpriced. - Legacy licensing changes have disabled prior purchases or force new subscriptions (bait-and-switch perception). - Lack of presets/save-and-load for different setups; data and configurations feel scattered/incoherent. - Usability and documentation gaps (non-intuitive UI, weak manual, workflow friction, compatibility concerns with newer devices). ## Similar extensions and apps - [SignalScope Pro 2026](https://chrome-stats.com/d/id6761435064) - [SignalScope Basic 2022](https://chrome-stats.com/d/id1644734171) - [SignalScope Pro 2020](https://chrome-stats.com/d/id1509796235) - [SignalScope Basic 2020](https://chrome-stats.com/d/id1520683649) — 5.00 / 5 - [SignalScope Advanced 2022](https://chrome-stats.com/d/id1644733179) - [SoundScope: Audio Toolkit](https://chrome-stats.com/d/id6755621768) - [SoundScope: Audio Analyzer](https://chrome-stats.com/d/id6758302945) - [Oscilloscope](https://chrome-stats.com/d/id388636804) — 4.10 / 5 - [SoundScope AI - Pro Noisemeter](https://chrome-stats.com/d/id6778124546) - [Noise Level Meter: Spectroid](https://chrome-stats.com/d/id6798899899) - [Signal Scope Studio](https://chrome-stats.com/d/id6801408561) - [Audio Spectrum Analyzer Pro](https://chrome-stats.com/d/id1152352806) — 4.40 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id1304775893)
