PSPaudioware – PSP Metra v1.0.0 for WiN

PSP Metra is a high-quality, real-time audio analysis and measurement module designed for engineers who need absolute confidence in loudness, dynamics, and stereo imaging. Designed exclusively as an analysis tool, Metra never alters the quality of your audio—its sole purpose is to provide clear and reliable information for making important decisions.

It combines professional-grade dynamics, stereo, and loudness metering in a single, unified interface, including sample and true peak, PPM, RMS, and VU, dynamic range and gain, stereo correlation and balance, goniometer and Lissajous displays, and fully standard-compliant loudness metering, including LUFS, LRA, built-in PLR, PSR, and additional dialogue loudness functions. Everything you need to confidently review modern mixes, mastering sessions, and broadcasts is always within sight.

Inspired by the clarity of classic plasma meters from the 1980s and built to today’s metering standards, the PSP Metra combines exceptional visual readability with state-of-the-art loudness compliance, making it the ideal solution for music production, studio mastering, and broadcast.

See what you’re really hearing

• PSP Metra provides a complete picture of your signal in real time:
• Peak, RMS, and loudness metering with selectable ballistics
• Dynamic range and gain monitoring for micro- and macrodynamics
• Stereo image analysis including correlation, balance, and inclinometer displays
• History and waveform views showing sound level changes over 120 seconds

Loudness You Can Trust

Built on industry standards, PSP Metra delivers comprehensive loudness analysis that meets today’s requirements:

• Momentary, Short-Term, and Integrated Loudness (ITU-R BS.1770 / EBU R128)
• True Peak Detection with oversampling for accurate monitoring of inter-sample peaks
• Loudness Range (LRA) for program-level dynamics
• PLR and PSR for headroom estimation and transient preservation
• Optional Dialogue Integrated Loudness using licensed Dolby Dialogue Intelligence™
  for accurate speech-based loudness metering in broadcast and streaming workflows
• Built-in presets instantly configure Metra for platforms like EBU R128, ATSC A/85, Spotify, Apple Music, and more, so you always know you’re hitting your targets.

Multiple Views, Single Purpose:

PSP Metra allows you to simultaneously display two different measurement panels on the left and right sides of the window. Each panel can independently display different measurement types, but the same view cannot be active on both sides simultaneously. Icon-based logic ensures that the display always displays multiple measurements. 

PSP Metra adapts to your workflow with dedicated views tailored to different production stages:

• Metra View – Complete overview of level, dynamics, balance and correlation
• Minimal View – Compact dosing tool for everyday mixing
• History View – Visually track levels, dynamics and time distribution
• Protractor and Lissajous views – Detailed control of stereo field and phase
• Loudness and Loudness Value View – Targeted loudness compliance monitoring
• Each view is designed to reduce visual clutter while still allowing important information to be read at a glance.

Designed for professionals

PSP Metra is designed for engineers who need accuracy, not interpretation:

• Stereo and mono operation with advanced mid and side frequency analysis
• Fully customizable scales, colors, and metering mode
• High-resolution, 100% scalable GUI
  • VST, VST3, AU, and AAX formats allow seamless DAW integration

Whether you’re balancing a mix, preparing a master file for streaming, or ensuring broadcast compliance, Metra gives you accurate data without the distraction.

Pure analysis, without coloration

PSP Metra doesn’t process your audio. It doesn’t clip, compress, or modify your signal in any way. With the exception of an optional weighted filter monitoring mode (for testing purposes only), what you hear remains untouched—what changes is up to you.
