【Voxengo频谱分析仪插件】Voxengo SPAN Plus

SPAN Plus是一个实时的“快速傅里叶变换”音频频谱分析仪插件，用于专业音乐和音频制作应用。在大多数情况下，它被来自Voxengo GlissEQ的动态参数均衡器，并再现它的频谱分析的功能。 SPAN Plus是一个免费跨度插件扩展版本：SPAN Plus提供一些额外的功能，如PNG文件，出口，的实时频谱进口/出口和静态频谱显示。

 SPAN加为您提供了一个非常灵活的“模式”系统，你可以用它来设置频谱分析仪喜好。您可以指定傅立叶块大小的样本中，FFT窗口重叠率，频谱的视觉坡。旁边的是，你可以选择所需的类型（例如实时非常大，非常大的所有时间）显示二级光谱。频谱可以平滑目测一个更加方便快捷的检查。

 SPAN Plus支持多通道分析，并可以被设置为显示在同一时间从两个不同的信道或信道组的频谱。频谱的颜色可以选择的味道。

 SPAN Plus还具有输出电平可调道和积分时间，K-系统计量（包括校准K-系统计量）计量。 SPAN加级计量统计显示，净空高度估计和裁剪检测。以及相关测光

SPAN Plus is a real-time “fast Fourier transform” audio spectrum analyzer plug-in for professional music and audio production applications.  For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality.  SPAN Plus is an extended version of the freeware SPAN plug-in: SPAN Plus provides several additional features such as PNG file export, real-time spectrum import/export and static spectrums display.

 SPAN Plus provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences.  You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope.  Beside that you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum).  Spectrum can be smoothed out visually for an easier examination.

 SPAN Plus supports multi-channel analysis and can be set to display spectrums from two different channels or channel groups at the same time.  Spectrum's color can be chosen to taste.

 SPAN Plus also features output level metering with adjustable ballistics and integration time, K-system metering (including calibration K-system metering).  SPAN Plus displays level metering statistics, headroom estimation and clipping detection.  Correlation metering is available as well
