SignalScope X
Version: 12
Requirements:
iOS 14+, macOS 11+
Price: Free
Faber Acoustical introduces SignalScope X as its flagship dynamic signal analysis, data acquisition, and acoustics app for iOS, iPadOS, and macOS. The culmination of 20+ years of development experience on Apple platforms, SignalScope X offers in-app subscriptions to replace and exceed the functionality previously found in other apps from Faber Acoustical, including SignalScope, which was available in the iPhone App Store on its opening day in 2008. SignalScope X is now available on the App Store as a free download.
SignalScope X 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.
