介绍
CEDAR是一个六十四位,高分辨率的音频处理平台。无论从最早期的录音或是今天的传输音频广播,它的一系列工具
都能让音频变得非常清晰,给你解决所有音频恢复和语音增强的需要。
完全模块化,有需要时更可以完全自动化。它使用自己的时间码阅读器/发生器,并且可以以实时多倍的速度处理
信号,若选择安装服务器包,还可以同时支持多个用户。

以最新推出的CEDAR CAMBRIDGE系列三硬件为基础, 在前版本之上加强几方面的升级和改善, 让第八代迈进了重要的另一
步。现在不但加入了支持视频的功能,还能同時分析、处理和播放八条视频。

在硬件结构的层面上,拥有扩展的文件处理系统,具有强大的新区域分类让它可以独立处理多个音频区域,并
大大延长其转录能力。
该系统还能提供输出映射,扩展了热键的部分,亦能实现播放、录制及处理192kHz音頻。

除了这一点,在其恢复和其他处理模块里它提供了大量的更新,如增强了的Retouch 5™Respeed™,在Power Normaliser
里加入了ITU1770-2和M-加权的标准,加上一个修订自适应限制器™,音頻限制和影响得到最大化的范围扩展。

与时俱进,CEDAR Cambridge V8仍然是后期制作公司,CDDVD母带工作室、广播、健全国家档案馆和图
书馆与许多世界上最重要的警察和安全部队的首选系统。

系统III硬件
CEDAR Cambridge系统III是一个伺服器级的強大处理系统。能让多个用户迅速同步处理更多的音頻。
它的八核处理器能提供比上一代多一倍的处理能力,能满足需要同步处理大量资料,或对多通道或批处理能力有要求的用户。

同样,当你考虑系列III的存储能力,其中包括本地存储能力持有约10,000个小时的无压缩音频标准3TB
这让系列III适合使用在如国家档案馆和图书馆要求苛刻的环境中,一个单一的CEDAR Cambridge系统便能同时服
务众多的工作室和用户。

时间码的自动化控制器
专用的时间码阅读器确保处理过的音频能保持与视频同步,CEDAR Cambridge能完美地和任何音频或视
频工作站协同工作。它还提供
CEDAR Cambridge全自动化设施所需要的处理参数。

音频模块和系统
这是CEDAR CAMBRIDGE一个不断成长的处理模块。可以在音频的所有领域中应用,并且你可以按需要选择合适的模块组合。
另外,我们可以推荐不同的系统。比如为电影声轨恢复和后期制作的
CEDAR Cambridge电影系统,为CDDVD进行音频
恢复的
CEDAR Cambridge母带系统,还有两个音频法证调查 - CEDAR Cambridge法证系统。

CEDAR Cambridge第八版的最新信息
第八版较之前的版本在很多个方面已焕然一新。
其中最显著的,视频回放系统现在已经可以从一系列的A/V格式中提取音频信息,并能在处理音频的同时在另
一个窗口让视频同步播放。可以应付多至八轨音频文档,系统会自动创建相应的视频窗口。

它拥有一个进一步扩展的文件处理系统。你不仅可以定义一个音频文件内的多个区域,现在更能分配这些到多
用户定义分类去分辨比如:在一个声道中的不同麦克风或场景;在一次谈话中的不同发言者;或在电话录制过程
中的各个发言者等。特别是当和报告发生器结合使用时,区域分类能给转录提供巨大的援助性能。

The system offers improved output mapping, an expanded Hot Keys section, and it has been upgraded to play, record and process at 192kHz. Other improvements include a a combined waveform/spectrogram view that shows both simultaneously to speed up the identification of audio events, a MIDI Note scale to augment the standard frequency axes, harmonic markers to aid the use of modules such as debuzz and the EQs, improved rendering and looping, and greater efficiency when handling large numbers of edits in modules such as Retouch 5.

Updates and improvements to existing modules
Version 8 also offers numerous updates within its restoration and other processing modules, such as new tools in the enhanced Retouch 5™ and Respeed™, the addition of the ITU1770-2 and M-weighted standards in the Power Normaliser, and a revised Adaptive Limiter™ that greatly extends the range of limiting and maximising effects obtainable.

Retouch 5™

Boasting numerous improvements, Retouch 5 introduces Previewing and a new Volume mode, which allow users to process - and listen exclusively to - selected areas of the spectrogram. There's also a new Pitch Shifter in the Patch and Copy modes. This invokes a genuine pitch shift algorithm that takes into account the relative pitch of components within the audio selection, greatly aiding the correction of errors in harmonically rich material. There's also a new paintbrush mode, and this allows you to pinpoint problems or draw broad sweeps to identify complex sounds such as aircraft flying overhead, or birdsong. Used together with the new MIDI Note scale, these tools even allow you to correct the pitches of incorrect notes within musical material.

Respeed™

With two powerful new functions - Hold and Invert - Respeed is now capable of creating a speed correction template using one audio file and applying it to another. Amongst other things, this allows users to correct the speed of multi-track material held in separate files before mixing. The new version is also able to invert a template and reapply it, which makes it possible to correct unusual problems such as wandering tones before returning the audio to its original state.

Respeed performs speed correction by identifying - or by allowing the user to identify - unwanted pitch changes contained within the presented audio. The benefits of this can include greater pitch stability and improved intelligibility.

Adaptive limiter 2

In response to feedback from our customers, we have enhanced the Adaptive Limiter, making it possible to apply even more limiting while retaining the integrity of the original audio. Not just a limiter, it's fair to say that the Adaptive Limiter is now an extremely flexible maximiser too, capable of pushing your audio far further than before without introducing unpleasant artefacts.

Power Normaliser 2

Featuring two further loudness standards, the Power Normaliser is now even more flexible for broadcast and cinematic production.

ITU1770-2 uses a 'gated loudness' approach that omits quiet passages (such as the gaps between utterances) from the gain calculations, making it particularly suitable for speech. In addition to this, there's now an M-weighted calculation, the standard being adopted by the film industry to assess audio loudness when listening at cinema playback levels.

Putting it all together
CEDAR Cambridge V8 is immediately available and runs on legacy CEDAR Cambridge Q systems as well as the latest CEDAR Cambridge Series III hardware running Windows 7 Ultimate 64-bit. Users are advised to upgrade to the latest specification to take advantage of all the new features.

As always, software upgrades to both the core system and to existing modules are provided free of additional charge to existing users. A full set of OS and hardware upgrade options are also offered.
