Faber Acoustical SignalScope XM Tool Set - Advanced — Free Download

Purpose and Scope

SignalScope XM is a professional-grade dynamic signal analysis and data acquisition application for Mac, built on two decades of Apple platform development. The Advanced Tool Set expands the basic package with specialized analysis and hardware support, designed for engineers and researchers in acoustics, audio, and electroacoustics. It turns a Mac into a versatile measurement system capable of handling complex signals.

The tool set includes a broad array of instruments: oscilloscope, FFT analyzer, spectrogram (2D and 3D), XY scope, stereo signal generator, octave analyzer, level meter, max levels, noise dosimeter, data recorder, and file player. This suite covers time-domain, frequency-domain, and statistical analysis, making it suitable for tasks ranging from simple signal viewing to detailed noise exposure assessment.

Key Capabilities

The Advanced Tool Set enhances measurement accuracy through automatic calibration. It auto-loads factory-supplied microphone sensitivities for select USB microphones, updates nominal voltage sensitivities for certain audio input devices, and performs automatic calibration when built-in sensitivity data is available. This reduces setup errors and improves reliability of absolute measurements.

For flexible input configuration, users can assign engineering units to input signals, calibrate external transducers, and set individual channel units and sensitivities for USB devices. The app supports connecting lab-grade microphones and sensors with suitable interfaces, and offers enhanced support for specific hardware from Digiducer, The Modal Shop, Dayton Audio, and miniDSP. Users can also manually switch between audio input and output sources.

Workflow and Data Handling

SignalScope XM supports loading microphone frequency response data (FRD) and applying frequency response correction (FRC) to FFT-based measurements. This is essential for accurate spectral analysis when using microphones with non-flat responses. Users can manually adjust audio sample rates up to a high limit depending on the input hardware, allowing for fine control over measurement bandwidth.

Acquired data can be saved in CSV, tab-delimited ASCII text, or MAT files, facilitating export to external analysis tools like MATLAB or Excel. High-resolution analyzer display images can be saved as PDF files, useful for documentation or reporting. The combination of these export options streamlines the path from measurement to analysis and presentation.

Practical Applications

The Advanced Tool Set is well-suited for acoustic measurements, such as room acoustics, noise monitoring, and sound quality evaluation. The octave analyzer and noise dosimeter are valuable for occupational noise assessments. The data recorder enables long-term logging for environmental or equipment monitoring. The signal generator paired with the oscilloscope can be used for impulse response testing or frequency response measurements.

For electroacoustic testing, the FFT analyzer with frequency response correction supports loudspeaker and microphone characterization. The XY scope can display Lissajous patterns for phase analysis. The file player allows playback of test signals or recorded data for auralization. These capabilities make the tool set a practical choice for development, troubleshooting, and field measurements in professional settings.
