SignalScope v 3.8
Mar 3, 2015
MacOS X Intel
Versions 3.8 of SignalScope, SignalScope Pro, and Electroacoustics Toolbox for Mac OS now offer built-in support for USB measurement microphones from miniDSP and Dayton Audio as well as the model 333D01 USB accelerometer from Digiducer.
Each app directly supports the miniDSP UMIK-1 and Dayton UMM-6 USB measurement microphones. Sensitivity calibration data for these mics can be downloaded automatically, just by entering the mic’s serial number. Making calibrated sound level measurements is as easy as plugging in the UMIK-1 or UMM-6, typing in its serial number, and getting started with the analysis tool of your choice (the serial number only needs to be entered once, after which the app will remember the microphone sensitivity). An internet connection is required to download sensitivity information for the microphone.
Each of these apps also directly supports the Digiducer 333D01 USB digital accelerometer, and can automatically load serial number and sensitivity calibration information directly from the device. Making calibrated acceleration measurements is as easy as plugging in the 333D01 and getting started with the analysis tool of your choice.
Various bugs and potential instabilities in each app have been corrected.
These apps all require Mac OS version 10.7 or later.
SignalScope v 3.7
Dec 4, 2014
MacOS X Intel
All Faber apps for Mac OS received updates to improve their compatibility with Yosemite (Mac OS 10.10). Electroacoustics Toolbox 3.7, SignalScope Pro 3.7, SignalScope 3.7 and SignalSuite 4.7 are all 64-bit applications that have been built for Yosemite.
The Room Analyzer tool, available for in-app purchase in Electroacoustics Toolbox, now calculates room parameters in whole or 1/3-octave frequency bands from impulse response data that has been sampled at higher sample rates (88.2, 96, 176.4, and 192 kHz), in addition to sample rates of 44.1 and 48 kHz that were supported previously.
The Octave Analyzer tool, found in both Electroacoustics Toolbox and SignalScope Pro, also now supports the higher sample rates for real-time spectral analysis of input signals in whole or 1/3-octave frequency bands.
The Dual FFT Analyzer (only in Electroacoustics Toolbox) and FFT Analyzer tools now support additional dB vertical scale factors of 3, 6, 9, 12, 15, or 18 dB per division in the graphic display.
Various bugs and potential instabilities in each app have been corrected.
