Restoration Suite 2 —— 音频质量的巨大飞跃

Restoration Suite 2 是一套包含四款尖端插件的音频修复与降噪套装。

DeNoise 2 是一款专为降低噪声而设计的插件,适用于抑制如嘶声、风噪、电流嗡嗡声以及摄像机噪音等。插件可通过自适应模式自动降噪,或通过噪声剖面模式在测量噪声特征后进行处理。2.0 版本新增了动态噪声剖面功能,能捕捉噪声随时间变化的动态特性,从而有效降低诸如风声这类波动性强的噪声。新算法的处理效果也大幅提升,降噪过程中更少出现常见的伪影。

DeHum 2 针对由接地不良的电气设备引入的嗡嗡声与电流杂音,也能处理其他类型的固定频率噪声,如电机噪声。2.0 版本中改进了嗡声检测算法,并新增了一个“扫描”按钮,可自动微调主频率以实现更精确的处理。

DeClick 2 旨在去除瞬时噪声,如点击声、爆裂声与重击声。这些失真常见于 LP 与 78 转老唱片,也可能出现在数字录音中,例如因掉包或数据失真导致的噪音。DeClick 2 的重击噪音处理对人声中不必要的爆破音也非常有效。2.0 版本的算法得到了优化,减少了对正常信号中起音和瞬态部分的影响。

DeClip 2 通过改进的算法,修复因模拟或数字削波而失真的音频录音。

2.0 版本新特性

四款插件的处理算法与用户界面相比前代版本都有重大改进。DeNoise 2 引入了“动态噪声剖面”功能,能有效降低如风噪或领夹麦克风产生的摩擦声等随时间波动的噪音。与早期版本仅记录固定噪声快照不同,动态剖面会采集噪声的统计特征,并据此估算出最适合输入信号的降噪阈值曲线。

DeNoise 2、DeClick 2 与 DeHum 2 现支持 Mid/Side(中/侧)处理模式,可减少立体声像中的不必要波动。DeClick 2 的核心算法大幅优化,可在提高点击与爆裂灵敏度的同时,避免产生不良伪影,更好地保留瞬态。

DeHum 2 新增自动微调按钮,可自动估算嗡声主频;嗡声跟踪与抑制效果也有所提升。DeClip 2 在音质方面进一步优化,可更真实地重建削波信号的峰值。

整套插件现已支持环绕声与沉浸式音频格式,最高达 7.1.6 声道。

Acon Digital Restoration Suite 2 提供 VST、VST3 与 AAX 插件格式,兼容 Windows 与 macOS,macOS 版本亦支持 AU 插件格式。Windows 提供 32 位与 64 位版本,macOS 为 64 位。

Restoration Suite 2 – a Giant Leap in Audio Quality

Restoration Suite 2 is a suite of four cutting edge plug-in for audio restoration and noise reduction

DeNoise 2 is a plug-in designed to reduce noise such as hiss, wind noise, buzz and camera noise. The noise can be reduced automatically in the adaptive mode or after measuring the characteristics of the noise in the noise profile mode. New in version 2 are dynamic noise profiles that capture the dynamic properties of the noise so that noise that fluctuates over time, such as wind noise, can be effectively reduced. The new algorithm has also been greatly improved and is now even less prone to typical de-noising artifacts.

DeHum 2 targets hum and buzz typically introduced by poorly grounded electrical equipment, but also other tonal noise sources like electrical motor noise. The hum detection algorithm has been improved in version 2 and there’s now a new Scan button that automatically fine tunes the fundamental hum frequency.

DeClick 2 is designed to remove impulsive noise such as clicks, crackle and thumps. These distortions are frequently encountered on LP and 78 RPM records, but also occur in digital recordings due to drop-outs or distorted data packets. DeClick 2’s thump reduction works also effectively on vocal recordings with unwanted plosives. The algorithm has been improved in version 2 and is now less prone to reducing attacks and transients in the wanted signal.

DeClip 2 restores audio recordings distorted by analog or digital clipping with an improved algorithm.

New in Version 2

All four plug-ins have received major improvements both in the processing algorithms and the user interface compared to version 1. DeNoise 2 introduces the novel dynamic noise profiles that help reducing noise that varies randomly over time, such as wind noise or rustle from lavalier microphones. Where the earlier versions merely captured a static noise print with time-constant noise levels, the dynamic noise profiles capture statistics from the noise to be reduced. The noise suppression algorithm then estimates the most suitable noise threshold curve for the noisy input signal using the measured statistics.

DeNoise 2, DeClick 2 and DeHum 2 now support Mid/Side (M/S) processing, which can reduce unwanted fluctuations in the stereo image. The core algorithm in DeClick 2 received major improvements and now better preserves transients and can be pushed to higher click and crackle sensitivities without introducing artifacts.

DeHum 2 has a new automatic fine-tune button that triggers automatic estimation of the hum noise frequency. The hum tracking and suppression have also been improved. DeClip 2 was improved in terms of audio quality and now offers even more impressive reconstruction of clipped signal peaks. All the plug-ins in the suite now support surround and immersive audio formats up to 7.1.6 channels.

Acon Digital Restoration Suite 2 is available as VST, VST3 or AAX for both Windows and Mac or as AU plug-ins for Mac. There are 32 and 64 bit versions for Windows and the Mac version is 64 bit.
