APU Software TrueGain v4.3.6 (Win/macOS)
 

To ensure its perceptual modeling is accurate, TrueGain features a straightforward calibration process that aligns the plug-in with the true Sound Pressure Level at your listening position. Using any standard SPL meter, you can match the plug-in to your physical environment, ensuring all loudness simulations are precise and repeatable.
Its two primary workflows are:
Compensated Gain Staging: Apply gain adjustments that maintain the perceived tonal balance of your source audio.
Translation Checking: Without changing your monitor volume, use the target SPL parameter to accurately simulate how your mix sounds at different levels-from quiet home listening to loud club playback.
A comprehensive, real-time spectral analyzer provides clear visual feedback on your source, target, and output signals throughout the process.
