Faber Acoustical SignalScope XM Tool Set - Pro — Free Download

Purpose and Scope

SignalScope XM is a dynamic signal analysis, data acquisition, and acoustics application for Mac, developed by Faber Acoustical over more than two decades. The Pro Tool Set is an in-app expansion that unlocks a comprehensive suite of basic, advanced, and professional measurement tools, making the app suitable for acoustics, audio, and electroacoustics work. It is designed for engineers, researchers, and technicians who need precise analysis capabilities on a Mac.

The Pro Tool Set augments the standard version with specialized hardware support: auto-loading factory microphone sensitivities for select USB microphones, updated nominal voltage sensitivities for some audio input devices, and automatic calibration when connected audio inputs include built-in sensitivity data. This allows for more accurate measurements with compatible external microphones and sensors.

Core Capabilities

The tool set includes a wide array of analyzers and instruments: oscilloscope, FFT analyzer, 2D and 3D spectrograms, XY scope, stereo signal generator, octave analyzer, level meter, max levels, noise dosimeter, data recorder, file player, dual FFT analyzer, sound intensity analyzer, room acoustics analyzer, MultiTool, and polar plot. These cover time-domain, frequency-domain, and statistical analyses for diverse measurement tasks.

Users can assign engineering units to input signals and calibrate external transducers. The app supports per-channel unit and sensitivity settings for individual USB audio devices, enabling direct connection of lab-grade microphones and sensors via suitable interface hardware. Enhanced support exists for select hardware from Digiducer, The Modal Shop, Dayton Audio, and miniDSP.

Workflow and Data Handling

SignalScope XM allows manual switching between available audio input and output sources, which is useful for comparing different sensors or monitoring systems. Users can load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT-based measurements, improving accuracy across the frequency range. Sample rates can be manually adjusted, up to 768 kHz depending on the connected input hardware.

Acquired measurement data can be saved to CSV, tab-delimited ASCII text, or MAT files for further analysis in external software. High-resolution analyzer display images can be saved as PDF files for documentation and reporting. These data export options facilitate integration with existing workflows in engineering and scientific settings.

Practical Applications

Typical use cases include room acoustics analysis, sound intensity mapping, noise dosimetry for workplace exposure assessment, and electroacoustic testing of speakers or transducers. The dual FFT analyzer supports transfer function measurements, useful for characterizing system frequency responses. The polar plot helps visualize directivity patterns of microphones or loudspeakers.

The data recorder and file player allow for offline analysis of recorded signals, while the MultiTool combines several measurements into one interface for efficient data collection. The Pro Tool Set is best suited for professionals who require high-precision, calibrated measurements and are willing to configure hardware to achieve them. It integrates with lab setups that already include acoustic sensors and interfaces.
