PSP Metra - Comprehensive All-in-One Metering Suite｜Professional Full-Featured Audio Analysis and Loudness Meter Plugin

The Ultimate Audio Analyzer and Metering Plugin for Precise Decisions

PSP Metra is an advanced real-time audio analysis and measurement plugin designed for audio engineers, aiming to provide absolutely reliable data for loudness, dynamics, and stereo imaging. As a pure analysis tool, Metra never modifies or processes your audio in any way. Its sole purpose is to provide clear, trustworthy visual information when you make critical decisions, ensuring your mixes and masters meet modern broadcast standards.

Compared to the basic level meters built into most DAWs, PSP Metra offers a comprehensive loudness meter suite covering Sample Peak, True Peak, RMS, VU, dynamic range, phase correlation, and compliance with international standards like EBU R128. Inspired by classic 1980s plasma meters and combined with modern measurement algorithms, it provides unparalleled accuracy and readability in music production, mastering, or broadcast engineering environments.

Who is PSP Metra for?

使用者建議分析(點此展開)

▼

適合誰購買

Mastering engineers who need to ensure their work complies with loudness standards for Spotify, Apple Music, or broadcast platforms.
Mixing engineers who want to precisely monitor dynamic range, peak levels, and mono compatibility during the mixing stage.
Sound designers working in film and television post-production who must deliver audio compliant with EBU R128 or ITU standards.
Advanced users seeking an integrated professional meter to replace multiple scattered analysis tools.

誰不適合購買

Beginners in music production who only need the basic level meters built into their DAW.
Users looking for tools with audio processing capabilities (e.g., limiters, compressors) rather than a pure analysis plugin.
Users with limited budgets who prefer free or entry-level analysis tools.

PSP Metra Core Technologies and Features

Comprehensive Metering Suite: All professional-grade measurement tools integrated within a single plugin, including peak meters, RMS/VU meters, dynamic range meters, phase meters, loudness meters, etc., eliminating the need to switch between multiple windows.
Industry-Standard Loudness Analysis: Full support for mainstream loudness standards such as EBU R128, ITU-R BS.1770-4, providing Momentary, Short-Term, Integrated LUFS, and Loudness Range (LRA) measurements to ensure compliance for releases on all platforms.
Efficient Dual-Panel Workflow: Allows simultaneous display of two different measurement panels on the left and right sides of the window, for example, monitoring loudness on the left and stereo image on the right, significantly improving analysis efficiency.
Pure Analysis, Zero Audio Processing: Strictly adheres to the principle of 'measure only, do not process'. Metra never applies any compression, limiting, or coloration to the audio path, ensuring that the sound you hear is identical to the original signal.
Advanced Stereo and Phase Detection: Provides Correlation and Balance meters, as well as Goniometer (stereo phase meter) and Lissajous displays, for in-depth analysis of stereo width and mono compatibility.
Clear and Intuitive Visual Design: Drawing inspiration from classic 1980s plasma meters, it offers excellent readability, allowing you to quickly interpret data and focus on mixing decisions rather than deciphering complex graphics.

Level and Dynamics Meters (Level & Dynamics)

Peak Measurement: Includes Sample Peak, True Peak, and PPM (Type I & II), precisely capturing the signal's highest peaks to prevent digital clipping.
Average Measurement: Provides RMS (Root Mean Square) and VU (Volume Unit) meters, reflecting human ear perception of loudness, suitable for assessing overall volume.
Dynamic Range Measurement: Features Dynamic Range and Crest Factor meters, used to assess the audio's macro dynamics (overall dynamic range) and micro dynamics (transient impact).

Stereo Imaging and Phase Meters (Stereo & Phase)

Correlation and Balance Meters: Real-time display of left and right channel phase correlation, helping to identify mono compatibility issues; the balance meter shows the left-right energy distribution of the stereo image.
Stereo Phase Meter (Goniometer): Visually represents the width, distribution, and phase status of the stereo field, instantly revealing issues like excessive width or phase shifts.
Lissajous Figure: Provides a more detailed graph of the left and right channel phase relationship, an advanced tool for diagnosing specific phase problems.

Loudness Compliance Meters (Loudness Compliance)

Multi-Time Scale Measurement: Provides Momentary, Short-Term, and Integrated LUFS readings for comprehensive monitoring of loudness changes.
Loudness Range (LRA): Measures the macro dynamics of program audio, an important indicator for assessing whether a work's dynamics are too wide or too compressed.
PLR and PSR: Provides Peak to Loudness Ratio (PLR) and Peak to Short-term Loudness Ratio (PSR) data for in-depth analysis of audio impact and loudness relationship.
Optional Dialogue Mode: Includes a Dialogue Integrated Loudness option, specifically designed for precise loudness measurement of dialogue-centric content in film, TV, and broadcast.
