一种基于频谱的限制与削波处理方案

受限,但不止于 “限”

音频限制(Audio Limiting)是管理与控制声音能量的技术。其核心目标通常是通过尽可能自然的方式调整音量动态,从而提升音频响度。在技术发展初期,人们通过电子电路实现这一功能:电路追踪音频信号的包络,再通过调节可变增益来降低信号峰值、提升低电平信号。后来,这些方法在数字领域得到模拟复刻,衍生出了各式各样的变体与风格。
LimitOne 则另辟蹊径。我们的目标并非取代其他所有削波器(clippers)或限制器 —— 毕竟它们各自都能赋予音频独特的音色质感 —— 而是研发一种全新的处理思路与方法,让你实现以往无法达成的效果。
我们的灵感来源于两阶段限制器技术与多频段压缩器设计,同时借鉴了削波处理在增添音色质感与冲击力方面的特性;此外,我们也关注到部分音频处理过程中可能出现的问题与失真瑕疵。随后我们设想:若不局限于现有技术,一款易用的音频处理工具应具备怎样的形态?这一思考最终催生出一种混合算法 —— 它融合了频域(frequency domain)与时域(time domain)数字信号处理的双重优势。

LimitOne 有何独特之处?

独特的混合算法设计

可在频域与时域同时实现自适应动态控制。LimitOne 包含两大核心算法,代号分别为 “河豚”(Pufferfish)与 “刺猬”(Hedgehog)。

河豚(Pufferfish)

一款频域处理器,核心作用是在设定的激励量(Drive)与阈值上限(Ceiling)下,优化整个频谱的能量分布。换一种表述:它是一款全自动的自适应多频段动态控制器。

刺猬(Hedgehog)

一款时域处理器,主要功能是对瞬态信号进行塑形。它采用一套自适应控制系统,且与 “河豚” 算法共用 “激励量(Drive)” 与 “阈值上限(Ceiling)” 这两个参数。

A spectral approach to limiting and clipping

Limiting, but not limited
Audio limiting is the art of managing and controlling sound energy. Often the goal is to increase loudness by changing level dynamics in the most transparent way possible. Historically, this was done by using an electric circuit that follows the envelope of an audio signal and steers a variable gain to reduce peaks and boost low levels. These methods were later emulated in the digital domain and many variations and flavors have been created since.

LimitOne is different. Our goal was not to eliminate all other clippers or limiters out there, as they all add their own color, but to develop a novel approach and do things in a different way, allowing you to get results that weren’t previously possible.

We found inspiration in two-stage limiter methods and multi-band compressor designs, in how clipping adds color and punch, and we also took note of the problems and artifacts that some processing introduces. Then we imagined what an easy-to-use tool would look like if we would not limit ourselves to existing methods. This led to the idea of a hybrid algorithm that combines the advantages of digital signal processing in the frequency domain and time domain.

What’s unique about LimitOne?
Unique hybrid algorithm design
Provides adaptive dynamics control in both frequency and time domain. LimitOne consists of two main algorithms, codenamed Pufferfish and Hedgehog.

Pufferfish
A frequency domain processor that aims to optimize the energy distribution across the whole frequency spectrum for a given Drive and Ceiling level. Another way to describe it: a fully automated adaptive multi-band dynamics controller.

Hedgehog
A time domain processor whose main purpose is to shape transients. It uses an adaptive control system that shares the same two parameters, Drive and Ceiling level.
