Electroacoustics Toolbox 3.2 k\'d 电声工具箱MAC版(间频分析采样)

流云高飞

电声工具箱是一个模块化，多通道动态信号分析仪和数据采集平台的Mac。它带来了强大的新工具，Macintosh平台的多通道，音频数据采集和实时分析电，声，和电声信号与系统。它能够精确测量的声学量，如等效时间加权声级，以及声学和电声系统，如听力室和扬声器。软件的设计工作与Mac兼容的音频硬件和支持8，16，24多个频道，或与采样率为硬件高32位数据将支持。

费伯声已经更新了电声工具箱的Mac OS X版本3.2，它现在提供两个额外的工具销售在应用程序通过应用程序购买。这些新的工具包括一个室内声学分析仪和噪声剂量计（类似于在早期版本的工具箱提供的剂量计的工具）。3.2版还将各种虫子。

房间分析仪

你一直在找的工具来测量混响时间，早期衰减时间，一个听音室，清晰度和定义的礼堂，在您的Mac或音乐厅？3.2版本的电声工具箱，搜索已经结束。在电声工具箱3.2你会发现一个新房间的声学分析工具（单独出售），把房间的声学分析在你的掌握。

新的空间分析工具采用集成的脉冲响应法计算混响时间，早期衰减时间，集中时间，清晰，和定义，如ISO 3382标准定义。房间分析仪还允许您可以点击并拖动鼠标或两个独立的数据指针调整施罗德衰减曲线积分限。你可以绘制计算房间的声学参数与整体或1倍频程带中心频率。

房间分析仪的特点：

直接分析脉冲响应（IR）获得的数据在双通道FFT分析仪和示波器的工具。

进口的脉冲响应从其他应用程序和存储在AIF，CAF获得，或者WAV音频文件。

出口参数的计算值为CSV，TXT文件，或垫，用该选项包括原始红外数据。

保存的脉冲响应（IR）数据AIF，咖啡，或WAV音频文件。

高分辨率图保存为PDF文件。

分析：

房间的声学参数计算根据ISO 3382，包括T20，T30，T60，EDT，C80，TS，C50，D50，和D80，在整个音频范围内，或1倍频程带。低，中，和高频率的每个参数的值也计算。

图室参数与整体或1倍频程的中心频率。

看到施罗德衰减曲线和回归线绘制在方IR和手动微调的衰减曲线积分限。

整个1 /倍频程分析，房间分析仪支持44.1 kHz和48 kHz的采样率数据。

噪声剂量计

电声工具箱3.2也带来了噪声剂量计的工具，在2版以前。剂量计的工具也单独出售
Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac. 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. 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. 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.



Faber Acoustical has updated Electroacoustics Toolbox for Mac OS X to version 3.2, which now offers two additional tools for sale within the app via in-app purchase. These new tools include a Room Acoustics Analyzer and a Noise Dosimeter (similar to the Dosimeter tool offered in earlier versions of the Toolbox). Version 3.2 also fixes various bugs.

Room Analyzer

Have you been looking for a tool to measure the reverberation time, early decay time, clarity and definition of a listening room, auditorium, or concert hall on your Mac? With version 3.2 of Electroacoustics Toolbox, the search has come to an end. Within Electroacoustics Toolbox 3.2 you will find a new room acoustics analyzer tool (sold separately) that puts room acoustics analysis in your grasp.

The new Room Analyzer tool employs the integrated impulse response method to calculate reverberation time, early decay time, center time, clarity, and definition, as defined in the ISO 3382 standard. The Room Analyzer also allows you to adjust the Schroeder decay curve integration limits with either a click and drag of the mouse or with two independent data cursors. You can plot the calculated room acoustics parameters versus whole or 1/3-octave band center frequency.

Room Analyzer Features:

Directly analyze impulse response (IR) data acquired in the Dual FFT Analyzer or Oscilloscope tools.
Import impulse responses acquired from other apps and stored in AIF, CAF, or WAV audio files.
Export calculated parameter values to CSV, TXT, or MAT files, with the option to include raw IR data.
Save impulse response (IR) data to AIF, CAF, or WAV audio files.
Save high-resolution plots to PDF files.
Analysis:
Calculate room acoustics parameters according to ISO 3382, including T20, T30, T60, EDT, Ts, C50, C80, D50, and D80, over the entire audio frequency range, or in whole or 1/3-octave bands. Low, mid, and high frequency values for each parameter are also calculated.
Plot room parameters versus whole or 1/3-octave center frequency.
See the Schroeder decay curve and regression line plotted over the squared IR and manually fine tune the decay curve integration limits.

For whole and 1/3-octave band analysis, the Room Analyzer supports data with sample rates of 44.1 kHz or 48 kHz.

Noise Dosimeter

Electroacoustics Toolbox 3.2 also brings back the Noise Dosimeter tool that was previously available in version 2. The Dosimeter tool is also sold separately
