SignalScope Pro 2026

SignalScope Pro 2026 offers a professional tool set to meet your measurement and analysis needs as an engineer, consultant, educator, student, researcher, or savvy hobbyist in areas such as acoustics (sound and vibration), audio, electronics, and electroacoustics.

Features:

• Analyze signals coming from available audio input hardware connected to your Mac or iOS/iPadOS 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 manufacturers including Digiducer, The Modal Shop, miniDSP, Dayton Audio, MOTU, and RME.
• Nominal acoustic sensitivities included for iPhone and iPad built-in microphones.
• 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 input hardware.
• Save acquired measurement data to CSV, tab-delimited ASCII text, 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:

• MultiTool - Powerful data monitoring and project management (Add up to 2 subtools on iPhone, 4-6 subtools on larger iPad and Mac screens, and save an arbitrary number of different configurations for easy recall at a later time.)
• Oscilloscope
• FFT Analyzer - Spectrum analyzer with user-settable frequency limits and signal triggering
• 2D Real-time Spectrogram Analyzer
• XY Scope - Create Lissajous curves on your Mac, iPhone, or iPad.
• Stereo Signal Generator

Advanced Tools:

• 3D Real-time Spectrogram Analyzer - Stunning live visualization of incoming data
• Octave-band Analyzer - Whole and 1/3-octave RTA
• Level Meter
• Max Levels
• 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:

• 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 FFT 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, manual or automatic adjustment of Schroeder integration limits)
• Polar Plot - Generate beautiful high-resolution plots of polar data loaded from properly formatted data in a text or csv file.
• 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

SignalScope Pro 2026 will receive major upgrades, consistent with those available in the SignalScope X Pro Tool Set subscription, through calendar year 2027, after which it will receive maintenance updates through 2029. It can be used indefinitely thereafter on a compatible version of macOS or iOS.
