多应用音频计量与监测插件
Trident Audio Developments推出的TriMeter是一款功能独特且不可或缺的监测工具，适用于多种音频应用和使用场景。它通过精心整合一系列行业认可的功能，并配备高度直观且可视化的界面，旨在提升专业音响工程师、录音艺术家、内容创作者及音频爱好者的多种工作流程与实践体验。
功能特点
VU表
TriMeter的两个VU显示模块经过精心设计，以匹配Trident传奇模拟调音台电表的规格和性能，提供了在数字音频领域常被忽视的一项基本功能。与数字音频工作站（DAW）环境中常见的峰值计量不同，VU表对人类耳朵的反应类似，能有效“平均”或“平滑”较短的瞬时峰值或瞬态，以获得更自然的响应。在数字应用中参考VU表，往往能带来更清晰的混音和更自然的音频制作效果。只需轻触按钮，即可启用-18 dBFS的0 VU校准，TriMeter还能帮助在录音过程中实现最佳的增益结构和足够的动态余量。
PPM表
虽然VU表具有诸多优势，如上所述，但PPM（峰值节目计量）往往能更清晰地指示更快速的水平变化和问题峰值。PPM表与DAW的峰值计量能力不同，它仍会掩盖最短暂的峰值或瞬态，而是提供与VU表互补的参考。TriMeter的双PPM实现位于每个VU表下方，其性能类似于经典Trident模拟调音台中的PPM表，同时还提供了一种混合的“削波保持”或过载指示器，用于指示超过0 dBFS等效值的信号。
LUFS表（综合）
LUFS（满量程响度单位）是测量和指定响度的最现代方法，也是行业标准。尽管VU和PPM等传统计量方式仍是数字环境中制作出色混音和音频项目的重要组成部分，但大多数广播和在线流媒体内容平台都指定了一个“目标”LUFS值，该值因组织而异。在线创作者，如播客或流媒体应用的内容制作者，越来越需要满足这些目标。与其他提供LUFS测量软件应用和插件的供应商不同，他们往往为高度专业化的行业用户开发复杂（且通常极其昂贵）的解决方案，而TriMeter独特的LUFS显示实现方式——尽管按照标准的精确规格设计——提供了一种简单且直观可视的方法，用于监测任何时长节目、表演或项目的综合LUFS。
线性输出增益控制
TriMeter图形界面的中心是一个旋转式输出增益控制。通过+/-18 dB的线性增益调整，可以降低或提高通道增益以满足各种需求，而不会为音频本身添加任何染色、非线性失真或“箱声”。
单声道混音
将两声道（立体声）音频混音为单声道是音频工程、混音和制作中常用的一种技术。例如，它可以有效地主观评估立体声混音或项目中左右平移音轨和内容的平衡。当处理两个输入通道时，TriMeter提供了一个便捷的一键混音切换功能。
极性切换
TriMeter提供了一键极性切换功能，对于诊断和纠正因麦克风放置或布线错误导致的可听相位问题非常有用。
应用示例
• 将TriMeter添加到任何音轨，以获得Trident调音台模拟的VU和PPM计量
• 将TriMeter添加到立体声总线/主输出，使用LUFS综合测量来评估音乐制作、播客和流媒体内容的响度目标
• 在跟踪时启用高动态余量VU监测（-18 dBFS），以帮助获得平衡良好、无失真的混音
• 将TriMeter添加到任何立体声音轨，并切换至单声道混音模式，以帮助平衡混音中的单个元素或平移
• 将TriMeter添加到任何立体声或单声道音轨，以进行简单的增益调整或极性反转
• 将参数映射到控制界面，实现快速便捷的操作

Multi-Application Audio Metering and Monitoring Plugin
TriMeter from Trident Audio Developments is a uniquely versatile and indispensable monitoring
tool, suited to a wide variety of audio applications and use cases. Through a selection of
meticulously implemented industry-established features, combined with a highly visual and
intuitive interface, TriMeter has been designed to enhance the many workflows and practices of
professional sound engineers, recording artists, content creators, and audio enthusiasts alike.
Features
VU Meters
TriMeter’s two VU displays, carefully modeled to match the specification and performance of
Trident’s legendary analog console meters, provide an essential function often overlooked in the
world of digital audio. Unlike the peak metering commonly found within DAW environments, VU
meters react similarly to the human ear, eEectively “averaging” or “smoothing” shorter
instantaneous peaks or transients for a more natural response. Referencing VU meters within
digital applications can often lead to clearer mixes and more natural sounding audio production.
With the ability to engage a 0 VU calibration of -18 dBFS at the touch of a button, TriMeter also
assists in achieving optimal gain structures and adequate headroom during recording.
PPM Meters
While VU metering offers many benefits such as those listed above, PPM or Peak Program
Metering can often provide a clearer indication of more rapid level changes and problematic spikes.
Not to to be confused with the peak metering capabilities of a DAW, PPM meters can and will still
mask the briefest of spikes or transients, instead offering a somewhat complimentary reference to
that of VU. TriMeter’s dual PPM implementations, located directly underneath each VU meter,
perform similarly to those found in classic Trident analog consoles, while additionally offering a
hybrid “clip hold” or over-level indicator for signals exceeding the equivalent of 0 dBFS.
LUFS Meter (Integrated)
LUFS (Loudness Units Full Scale) is the most modern method – and the industry standard – for
measuring and specifying loudness. While legacy metering such as VU and PPM still forms an
essential part of producing great sounding mixes and audio projects within digital environments,
the majority of broadcast and online streaming content platforms specify a “target” LUFS value,
which can vary greatly between organizations. Online creators, such as podcasters or content
producers for streaming applications, are increasingly tasked with meeting such targets. Unlike
other providers of LUFS measurement software applications and plugins, who often develop
complex (and often extremely expensive) solutions to highly specialized industry users, TriMeter’s
unique LUFS display implementation – while engineered to the exacting specifications of the
standard – offers a simple and visually intuitive method for monitoring integrated LUFS throughout a
program, performance, or project of any duration.
Linear Output Gain Control
Located in the center of the TriMeter graphical interface is a rotary output gain control. With +/- 18
dB of linear gain adjustment, channel gain can be decreased or increased to meet any number of
requirements, without adding any coloration, non-linear distortion, or “box sound” to the audio
itself.
Mono Summing
Summing two channels of (stereo) audio to mono is a technique often used within audio
engineering, mixing, and production. For example, it can be an effective way of subjectively
assessing the balance of left and right panned tracks and content within a stereo mix or project.
TriMeter offers a convenient one-button sum toggle function, when two input channels are being
processed.
Polarity Toggle
TriMeter offers a one-button polarity toggle function, often extremely useful for diagnosing and
correcting audible phase issues resulting from microphone placement or cabling errors.
Example Applications
• Add TriMeter to any track for Trident console-modeled VU and PPM metering
• Add TriMeter to a stereo bus/master, using LUFS integrating measurement to assess
loudness targets for music production, podcasts, and streaming content
• Activate high headroom VU monitoring (-18 dBFS) when tracking to assist with obtaining a
well-balanced, distortion-free mix
• Add TriMeter to any stereo track and toggle the Mono Sum mode to assist with balancing
individual elements or pans within a mix
• Add TriMeter to any stereo or mono track to make simple tweaks to gain or invert polarity
• Map parameters to a control surface for quick and easy operation
