乔丹博士设计 – 用于心理声学测量的APx插件
Dr. Jordan Design – APx Plugin for Psychoacoustic metrics
Audio Precision为使用APX软件进行自动音频测量提供了一个强大的框架。除了广泛的内置测量功能外，序列模式下的插件接口还可以模块化加载扩展功能。
心理声学测量技术领域，其基础由Zwicker等人在几十年前开发。近年来越来越重要。
通过Dr. Jordan Design的开发，可以将各种心理声学参数作为插件记录在APx软件中。计算的基础是Dr. Jordan Design的软件Akulap。Akulap是一款功能强大的音频分析软件，涵盖了广泛的音频，声学和心理声学测量技术。
因此，Dr. Jordan Design 的软件提供了一个复杂的心理声学模型作为 APX 系列的插件，该模型除其他外，根据 DIN45631/A1 计算宋(Sones)的时变响度。该插件无缝融入序列模式，因此您可以使用APX软件的所有测量功能和评估。响度的计算是在背景中使用 Akulap 完成的。[注]
**Sone：A unit of subjective loudness, equal to 40 phons.
**宋：主观响度单位，等于 40 方。
该插件与APx系列的任何音频分析仪兼容。

Product information “Dr. Jordan Design – APx Plugin for psychoacoustic measurements”
With the APX software, Audio Precision offers a powerful framework for automatic audio measurements. In addition to extensive built-in measurement functions, the plug-in interface in sequence mode enables the modular loading of extended functions.
The field of psychoacoustic measurement technology, the foundations of which were developed by Zwicker et. al. laid decades ago has gained in importance in recent years.
Through the development of Dr. Jordan Design, various psychoacoustic parameters can be recorded in the APx software as a plugin. The basis for the calculation is the Akulap software from Dr. Jordan design. Akulap is a powerful audio analysis software that covers a large area of audio, acoustic and psychoacoustic measurement technology.
The software from Dr. Jordan Design therefore offers a complex psychoacoustic model as a plugin for the APX family, which, among other things, calculates the time-variant loudness in sones according to DIN45631/A1. This plugin fits seamlessly into the sequence mode so that you can use all measurement functions and evaluations of the APX software. The loudness is calculated in the background with Akulap.[nbsp]
The plugin is compatible with any audio analyzer of the APx series.
Psycho-acoustic measurements
- Loudness in sons (ISO532B)
- Time-variant loudness DIN45631/A1 and ISO532-1
- specific loudness
- Sharpness according to DIN45692
- Tonality DIN45681
- Roughness (Daniel[&]Weber)
- impulsiveness
- Presentation of psychoacoustic parameters over time
