SignalScope X’s Pro Tool Set Subscription includes access to a suite of basic, advanced, and professional analysis tools, plus ongoing hardware support, such as periodically updated nominal microphone sensitivities for built-in microphones on Apple devices, updated nominal voltage sensitivities for select audio input devices, and automatic calibration for audio input devices that include built-in sensitivity information. An active Pro subscription will also grant access to any additional basic, advanced, or pro analysis tools added to new versions of SignalScope X.

The Pro Tool Set Subscription includes:

Standard 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 input hardware.
  • Save acquired measurement data to CSV, tab-delimited ASCII text, 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).
Pro Features:
  • In order for this subscription to be activated in SoundMeter X, you need to be sure that you are signed into your iCloud account when the subscription is active in SignalScope X. Then, SoundMeter X will be able to recognize and apply the subscription.
  • If you then use SoundMeter X on another device, please be sure that you are signed into the same iCloud account on that device in order to synchronize your subscription status between apps and devices.
  • If you have already purchased the Pro Tool Set subscription in SoundMeter X, then SignalScope X should recognize it and apply it. If SignalScope X does not recognize the Pro Tool Set purchased in SoundMeter X, please ensure that you are signed into your iCloud account, as indicated above. Depending on your network connection status and the behavior of iCloud, it may take some time to synchronize the subscription data between apps and devices, although synchronization should typically occur within a few seconds.

Regarding your subscription:

  • Payment will be charged to your iTunes Account at the end of the free trial period, unless you have turned off automatic renewal. If the free trial has already expired, payment will be charged at confirmation of subscription purchase.
  • Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
  • Your account will be charged for renewal within 24 hours prior to the end of the current period for the same price as the current period (shown above).
  • You may manage your subscriptions and auto-renewal may be turned off by going to your iTunes Account Settings after purchase (Account Settings may be accessed in the App Store app on your iOS device).
  • Any unused portion of the free trial period will be forfeited when you purchase a subscription, where applicable.
Perpetual License Option: The same tools and features found in the Pro Tool Set Subscription are also available in SignalScope Pro 2022.
