SignalScope X offers a range of powerful measurement and analysis tools to enhance your productivity in areas such as acoustics (sound and vibration), audio, electronics, and electroacoustics.

SignalScope X includes a free oscilloscope tool. SignalScope X makes additional tools available via 3 tiers of subscription-based tool sets to meet your basic, advanced, and professional needs. Each subscription works on your iPhone, iPad, and Mac.

Features:
- Analyze signals coming from the Mac or iOS device’s current audio input 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 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 hardware.
- Save acquired measurement data to CSV, TXT (tab-delimited), 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).

Release notes:
- The Spectrogram now supports user-selected min and max frequencies.
- The Spectrogram now supports graphing with time on the vertical axis (consistent with a typical LOFARgram).
- The Spectrogram includes an Auto Stop function for stopping after a user-defined period of time.
- When exporting Spectrogram data to a file, the magnitude data will be stored as decibel values when the dB scale is selected for magnitude values in the display settings.
- Support added for the latest Digiducer USB Digital Accelerometer models.
- Other cosmetic and minor improvements.
