HRX录音
HRX是我们用高分辨率记录在数据光盘上的WAV音频文件。这些文件包含精确的比特位复制的参考记录的主录音。他们是高保真的终极两声道录音！
参考录音（Reference Recordings）多年来一直坚持采用尽可能高分辨率的录音。我们从模拟磁带开始。我们不满意的早期技术，16位数字录音，但很快就开始制作HDCD（高清晰度兼容的数字）的录音，在这过程是由我们自己的录音大师Keith O. Johnson设计。在许多人看来，这些可能是有史以来最好的数字录音。目前我们的记录在176.4千赫/ 24位，带HDCD，这就是我们制作的HRX盘。与任何录音公司一样，我们长期以来对消费者录音格式的局限性感到沮丧：LP, CD, SACD, DVD-A, etc.
长期以来，除了我们的录音和掌握团队之外，没有人能听到我们录音的全部美丽！所有的消费录音格式都降低了主磁带的真实声音，要么是因为格式本身的限制，要么是回放设备的限制。电脑音乐播放的新前沿，我们赞扬那些勇敢的先锋音响！在HRX WAV音频文件与我们的主录音母带记录是完全一样的。只要您使用的播放系统不转换或损坏记录数据，它们将听起来像我们的录音母带记录的一样美妙。
技术概述Technical Overview
我们提供的文件中精确的数字数据是从我们的主录音母带直接复制的。它们被加载到一台计算机或服务器上，该计算机或服务器已安装了播放器软件和一个特殊的声卡，以提供精确的定时信号来操作外部的高质量数模转换器（或DAC）。我们的版本是两个通道，24位高分辨率的复制，取样频率为176.4千赫，这是专业行业多年来使用的相同的PCM格式。
制度的优点
系统格式的优点Merits of the System
这是第一次，你处于音频文件制作链的顶端。你将体验清晰，超高分辨率和诱人的轻松聆听-和录音师，唱片制作人听到同样的演绎。旧版本的录音格式有过滤器、磁带录音机、记录刀具和编码装置，在音频文件制作链的下端，它们掩盖了这种母带的演绎效果。
艺术进步Advances in the Art
高速数据传输和强大的处理是当代媒体的基础。新的技术正在取代旧的方法，这些旧方法必须对声音进行妥协使的录音适应早期的发行格式。消费者高保真度始于1950，以其当时最先进的专业设备。高分辨率系统正在从模拟的发展道路中涌现出来。
Starting 2017, the Reference Recordings website will also offer 176.4 kHz/24 bit downloads of many titles. These files are the same as the files on our HRx Discs. You have a choice to buy discs or download files! Links showing available formats will be on the page describing each title.
Technical Overview
We supply files that have exact copies of digital data from our master recordings. These are loaded to a computer or server that has been set up with player software and a special sound card to provide precisely timed signals to operate an external high quality digital to analog converter (or DAC). Our releases are two channel, 24 bit high-resolution copies that are sampled at 176.4 kHz, the same PCM formats that have been used by the professional industry for many years.
Merits of the System
For the first time, listeners are at the top of the food chain. They will experience clarity, resolution, and a seductive ease of listening – the same presentation production people, like ourselves, hear at sessions and from masters. Older release formats had filters, tape recorders, record cutters, and coding devices further down the chain that obscured or veiled this experiential connection or collective consciousness.
Advances in the Art
High-speed data handling and powerful processing are fundamental to contemporary media. Technology is replacing old methods, which had to compromise sound in order to fit the recording to the early release formats. Consumer High Fidelity began in the 1950’s with professional equipment that was state of art for its time. High-resolution systems are emerging from a similar development path.
Typical Equipment
When we first made HRx discs available, we used a simple Dell computer with Microsoft XP operating system for playback. We downloaded and set up Media Monkey as its player. A Lynx AES 16 card was installed to provide a re-clocked ultra low jitter professional AES signal. A single cable routed this signal to an outboard digital to analog converter unit. We like the Berkeley Audio Design Alpha DAC, which can drive a power amplifier directly and eliminate preamplifiers and cables from the system. Programs are loaded from DVD recorded optical discs and the data becomes WAV files to the player. These are presented as a track list that can be played from mouse or remote control commands. This early computer music system still works fine, though there are many other high resolution playback options available now, including multi-format disc players such as the OPPO.
