SignalScope Pro 2022
Version: 12
Requirements:
iOS 14+, macOS 11+
SignalScope Pro 2022 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.
SignalScope Pro 2022 requires at least iOS 14 or macOS 11 and runs beautifully on Mac (with Intel or Apple silicon), iPhone, and iPad with a single purchase.
SignalScope Pro 2022 will receive major upgrades, consistent with those available in the SignalScope X Pro Tool Set subscription, through calendar year 2023, after which it will receive maintenance updates through 2025. It can be used indefinitely thereafter on a compatible version of macOS, iPadOS, or iOS. We cannot predict compatibility with future operating system versions.
Features
Standard Features:
Pro Features:
- Multi-channel, real-time analysis of signals coming from the Mac or iOS device’s selected audio channels
- Multi-channel, real-time analysis of AIF, CAF, or WAV audio files
- 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 input hardware.
- Save acquired measurement data to CSV, tab-delimited ASCII text, or MAT files.
- Save time domain data to AIF, CAF, or WAV audio 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).
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
- Load data from multiple data files to generate average curves in the FFT, Octave, and Dual FFT tools.
