自动均衡和恢复音频插件 – Acon Digital DeFilter 1.2.0 WIN

Win/Mac | File size: 16/25 MB

DeFilter 是一种有效的工具,可以平衡录音中的音调不平衡或减少频谱中的共振峰或谷。甚至可以解决诸如梳状滤波器效应或来自未经处理房间的驻波之类的严重问题。 DeFilter 可以将录音与目标配置文件(例如音乐或语音)相匹配,或者从源(大笔画)中提取整体音色,同时消除狭窄的波峰和波谷。后者有效地消除了共振和梳状滤波器效应,同时保留了输入信号的音调特征。还可以对录音进行均衡以匹配参考录音。

我们非常小心地提供了一个易于使用的用户界面。可以使用自定义曲线定义与频率相关的校正级别,以便 DeFilter 可以专注于有问题的频率范围,同时不影响其他频率区域。输入和输出信号的实时频谱分析仪可视化对频谱的影响。

DeFilter is an efficient tool to even out tonal imbalances in a recording or reduce resonant peaks or dips in the frequency spectrum. Even severe issues such as comb filter effects or standing waves from untreated rooms can be addressed. DeFilter can match recordings to target profiles such as music or speech, or alternatively extract the overall timbre from the source – the large strokes – while evening out narrow peaks and dips. The latter removes resonances and comb filter effects effectively while preserving the tonal character of the input signal. Recordings can also be equalized to match a reference recording.


Great care has been taken to provide a user interface that is straightforward to use. Frequency dependent correction levels can be defined using custom curves, so that DeFilter can focus on problematic frequency ranges while leaving other frequency regions untouched. Realtime spectrum analyzers for both the input and output signals visualize the effect on the frequency spectrum.

Use Cases
Fix issues in a mix prior to mastering
Reduce resonances caused by untreated room acoustics
Matched equalization (automatic equalization based on a reference signal)
Improve clarity and intelligibility of speech
Instant fix for nasty comb filter effects
