安装方法：使用KeyGen注册机激活版本。
APU TrueGain 是一款等响度补偿增益控制插件，旨在在不同聆听音量下保持音频混音的感知音调平衡。
“补偿增益控制”预设设置了该工具，当您调整增益旋钮时，音频的频率响应会自动补偿，以保持感知音调平衡。
“转换检查”预设允许您模拟混音在不同响度级别下的声音效果，而无需更改监听音箱或耳机的实际音量。这可以帮助您快速检查低音的保持情况，或者在较安静的聆听环境中人声是否会变得刺耳，从而确保您的混音能够可靠地转换。
频率补偿 FIR 滤波器实现了 ISO 226:2023 和 ISO 226:2003 等响度轮廓。这些滤波器在所有采样率下都经过严格的公差要求验证。如果您想体验更具复古特色的音效，还可以选择经典的 Fletcher-Munson 轮廓选项，该选项基于 1933 年的原始论文。
所有增益和频谱调整均采用平滑插值，并可配置平滑时间以控制响应速度，并有助于防止增益自动化过程中出现任何可听见的伪影。您可以选择线性相位或最小相位滤波器类型。
为了提供详细的视觉反馈，TrueGain 包含一个功能全面的实时频谱分析仪。它具有可配置的 FFT 大小、窗口类型和时间平均功能。频率显示可以在线性、对数或音符刻度之间切换，并具有可调节的 dB 范围和自动缩放功能，帮助您专注于重要事项。
为了获得最佳效果，您可以使用外部声压级计根据您的特定聆听环境校准 TrueGain。这可确保等响度轮廓与您聆听位置的实际声压级准确对齐。
如果您没有声压级计，或者您正在使用耳机，您仍然可以通过选择与您的典型聆听音量相匹配的参考声压级来有效地使用 TrueGain。参考声压级滑块旁边提供了一些预设，涵盖了一系列常见的聆听级别。
APU TrueGain is an equal-loudness compensated gain control plugin designed to maintain the perceived tonal balance of an audio mix at different listening levels.
The ‘Compensated Gain Control’ presets setup the tool so when you adjust the gain dial, the frequency response of the audio is automatically compensated to preserve the perceived tonal balance.
The ‘Translation Check’ presets allow you to simulate how your mix will sound at different loudness levels without changing the actual volume of your monitors or headphones. This helps you quickly check how the bass will hold up or if the vocals will become harsh in quieter listening environments, ensuring your mix translates reliably.
The frequency compensation FIR filters implement both ISO 226:2023 and ISO 226:2003 equal-loudness contours. These filters are validated with rigorous tolerance requirements at all sample rates. For more of a vintage character, there’s also a classic Fletcher-Munson contour option, which is based on the original 1933 paper.
All gain and spectral adjustments are interpolated smoothly, with configurable smoothing times to control the responsiveness and help prevent any audible artifacts during gain automation. You can select between linear phase and minimum phase filter types.
To provide detailed visual feedback, TrueGain includes a comprehensive real-time spectrum analyzer. It features configurable FFT sizes, window types, and time averaging. The frequency display can be switched between linear, logarithmic, or musical note scales, with an adjustable dB range and auto-zoom to help you focus on what matters.
For the best results, you can calibrate TrueGain to your specific listening environment using an external SPL meter. This ensures that the equal-loudness contours are accurately aligned with the actual sound pressure levels at your listening position.
If you don’t have an SPL meter, or you’re using headphones, you can still use TrueGain effectively by selecting a reference SPL level that matches your typical listening volume. There are presets available next to the reference SPL slider which cover a range of common listening levels.
