![]() Level calibrationįull-scale output on the UA-25EX is 4.6V RMS. These are Mac programs but there are Windows equivalents. The measurement programs that I am using are FuzzMeasure Pro and the Electroacoustics Toolbox. Since I’m hoping to get a review out of the newer soundcards, I thought the older one would be a good example to use for this, as it also provides a reference to demonstrate how dramatically technology (for a given cost) has improved in a few short years. I’m using this one as an example because I’m replacing it. What's New in Version 3.9.10 This version fixes a bug in the display of vertical log scale axis values in the Spectrogram.This is an example of the measurement protocol described in A simple test protocol for USB/Firewire soundcards. AppleScript support for measurement automation and remote control No arbitrary limits on how many devices or channels are used, or on sample rates or signal formats-these are limited only by your hardware ![]() Work with multiple independent audio devices simultaneously Exporting data to ascii text or MAT-files for easy import into other applications Saving complete configurations and data in project files Support for units, including Volts, Amps, pascals, and Engineering Units Whole device and individual channel sensitivity (level) calibration Advanced control over input and output devices Quartz-based graphics for high-resolution still images and prints Hardware-accelerated OpenGL graphics for fast real-time plotting The Toolbox also offers advanced capabilities for configuring input and output device parameters and assigning labels, units, and transducer sensitivities to individual input and output channels. However, there is no requirement that all tools must work with the same device. The oscilloscope and FFT analyzers may each simultaneously analyze multiple input channels of a single device. For example, a project may contain an oscilloscope, two FFT analyzers, and two signal generators. Electroacoustics Toolbox allows for the creation of an arbitrary number of tools of a certain type, or tools of different types. Projects may contain one or more tools available in the toolbox, along with any captured data associated with those tools. Noise Dosimeter tool for measuring noise dose with various threshold and criterion levels, with 3, 4, and 5 dB exchange rates.Įlectroacoustics Toolbox is a project-based application, which allows you to configure and save project files. Room Analyzer tool for estimating room acoustics parameters from impulse response data (T20, T30, T60, EDT, Clarity, Definition, Center Time). Flat, A, and C-weighted equivalent (Leq), time-weighted (Lp), and percentile-exceeded (Lx) sound levels Signal mean, variance, and standard deviation values Crest factor and rms, peak, and peak-to-peak signal levels The software is designed to work with any Mac-compatible audio hardware and supports multiple channels of 8, 16, 24, or 32-bit data with sample rates as high as the hardware will support. It enables precise measurements of acoustic quantities, such as equivalent and time-weighted sound levels, as well as acoustic and electroacoustic systems, such as listening rooms and loudspeakers. It brings powerful new tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform.
