APU Software has announced the release of a powerful utility plugin which corrects the tonal balance of a mix as it changes depending on the listening level.
By modeling the human ear’s frequency sensitivity at different Sound Pressure Levels (SPL), TrueGain allows you to audition and control your audio with perceptual consistency.
The core of TrueGain is its ability to perform “translation checks.” After a simple one-time calibration to your monitoring setup, you can use TrueGain to simulate how your mix will sound at different loudness levels, all without changing the actual volume of your monitors or headphones. This allows you to quickly check how the bass will hold up or if the vocals will become harsh in quieter listening environments, ensuring your mix translates reliably.
Alternatively, TrueGain can function as a perceptually-compensated gain control. In this mode, as you adjust the output gain, the plugin automatically applies the corresponding frequency compensation. This preserves the perceived tonal balance of your mix as it gets louder or quieter, making it an invaluable tool for your master bus, monitoring chain, or in live sound applications.
APU TrueGain for Windows and Mac (VST3, AU and AAX) is available to purchase for $40 USD. A trial version is available to try to the plugin.
In addition to the release of TrueGain, version 4.2.0 of the APU Loudness Series comes with the following changes:
- Improved frequency response precision, particularly for minimum phase (contour).
- High-pass filter support for all filters (contour).
- Smoother switching of contour types (contour).
- Improved contour zoom (contour).
- Ballistics cross-fading improvements (contour).
- Tweak contour range detection (contour).
- Filter loading optimization (contour).
- Fix crash on loading NONE filter. (contour).
- Skew input/output gain rotary dials to avoid accidental massive gain changes.
