Audio device and analyzer configurations and acquired data can be saved in project files. Each analyzer now resides in its own independent window. 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. 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 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. 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. These apps all require Mac OS version 10.7 or later.Īll Faber apps for Mac OS received updates to improve their compatibility with Yosemite (Mac OS 10.10). Various bugs and potential instabilities in each app have been corrected. Making calibrated acceleration measurements is as easy as plugging in the 333D01 and getting started with the analysis tool of your choice. An internet connection is required to download sensitivity information for the microphone.Įach 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 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). Sensitivity calibration data for these mics can be downloaded automatically, just by entering the mic’s serial number. 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.Įach app directly supports the miniDSP UMIK-1 and Dayton UMM-6 USB measurement microphones. Weighting can be applied to the time-domain input signals before spectral analysis is performed, or applied to the results of a previously computed FFT magnitude. These curves were developed to mimic human perception of loudness at low and high sound levels, respectively. This offers results superior to synthesized fractional octave band filtering using an FFT.Īlso new in SignalScope Pro is frequency weighting based on the standard A and C frequency weighting curves. The filtering is performed in real time by digital Butterworth filters, as recommended by ANSI standards. SignalScope Pro also adds octave and third-octave band spectral analysis, like a traditional RTA. View single or dual-channel output from two analyzers simultaneously, or arrange a single analyzer for viewing dual-channel output with one channel in each display. Dual signal displays can be configured independently for a variety of visualization options. SignalScope Pro provides tremendous flexibility when it comes to viewing audio signals in real time.
