Features & Capabilities

SignalScope X offers a range of powerful measurement and analysis tools to enhance your productivity in areas such as acoustics (sound and vibration), audio, electronics, and electroacoustics.

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

User Reviews

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).

I have used this app for years, primarily as a teaching tool with my iPhone microphone. For some reason, it is no longer working. It will either start to record, then stop. Or it won’t work at all. The Faber SLM app seems to be working fine, so I’m not sure why the oscilloscope and FFT have stopped functioning. Very disappointing especially considering the price we pay for the subscription.

I've been kicking the tires to decide whether to subscribe. Right off the bat I was mystified by the apparent lack of the ability to store and retrieve various setups (after setting up a tool and its parameters) for making different measurements and/or setting up different displays. Since there is no manual, and the meager help file doesn't address this, as best as I could determine the software just retains the setup that exists when the program is quit. That limitation seems very odd. In general, a manual would help.
