Avions de Transport Regional ATR系列属于双发涡轮螺旋桨支线飞机,由法意合资的区域运输机公司研制生产。ATR(Avions de Transport Regional)即区域运输机公司,是法文和意大利文“区域运输机”的略语,1980年,法、意的两公司达成协议,决定共同研制一种中、小型支线客机。由法国航宇公司和意大利阿莱尼亚公司联合成立,1981年10月成立,1982年2月5日正式建立经济利益集团(GIE),总部设在法国图鲁兹。目前,由于乘坐舒适性及飞行速度等原因,民机市场上支线客机趋向喷气化,涡桨时代已过去,诸如SAAB等生产涡桨式支线运输机的飞机制造公司均已停产,而ATR公司设计制造的ATR系列是少数还在研制生产的飞机制造企业,目前已占据大部分涡桨式支线运输机市场。

   关于ATRAC的意思,计算机专业术语名词解释
    即Adaptive TRansform Acoustic Coding,自适应声学转换编码技术。是一项基于听觉心理学领域的研究和不损伤可闻声质量的数码音频译码压缩技术,对音乐资讯有效的进行压缩,压缩的比率为原来的五分之一,因为MD使用了ATRAC压缩技术,这样的压缩大大节省了许多空间,所以 CD的碟片要120mm大小,而MD只需64mm就可以录下74分钟的音乐。ATRAC压缩技术主要是利用了人耳的蔽遮效应,在心理声学原理上,在进行音频录入的同时,有许多外部的频段同时也会被录入,当人耳同时听到两个不同频率、不同音量的声音时,音量较小的低频及音量较小的高频连同不为人耳所察觉的频段信号都会被自动减弱或忽略不予记录,因此又可以称为适应性变换声码技术,由于近年肀嗦胙顾跫际(ATRAC的版本)越碓匠墒欤所以经过编码解码过程后的声音仍直逼CD,大家就不必担心音质差啦。
