SignalScope

This app, SignalScope 3, is no longer recommended for purchase. It has been replaced by SignalScope X and SignalScope Basic 2022, which run on newer versions of macOS, iPadOS, and iOS.

SignalScope 3 builds on SignalScope's tradition of award-winning design and precision measurement capabilities by building on advanced technology developed for Faber Acoustical's flagship product, Electroacoustics Toolbox.



SignalScope is a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac. It brings powerful tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. The software is designed to work with any Mac-compatible audio hardware and supports multiple channels of 8, 16, 24, or 32-bit data with sample rates as high as the hardware will support.

Built-in Tools:
- FFT Analyzer
- Oscilloscope
- Spectrogram
- X/Y Plotter

Additional Measurements:
- Signal-to-noise ratio (SNR)
- Total harmonic distortion (THD, THD+N)
- Crest factor and rms, peak, and peak-to-peak signal levels
- Signal mean, variance, and standard deviation values
- And more!

SignalScope is a project-based application, which allows you to configure and save project files. Projects may contain one or more tools available in the toolbox, along with any captured data associated with those tools. SignalScope allows for the creation of up to two tools of a each type. For example, a project may contain an oscilloscope, two FFT analyzers, and two spectrograms. The oscilloscope and FFT analyzers may each simultaneously analyze multiple input channels of a single device. SignalScope also offers advanced capabilities for configuring input device parameters and assigning labels, units, and transducer sensitivities to individual input channels.
