APU TrueGain是一种等响度补偿的qain控制插件，旨在保持不同听力水平下audoi混音的感知音调平衡。

“补偿增益控制”显示了设置傻瓜，因此当您调整qain拨盘时，audoi的频率响应会自动补偿，以保持感知的音调平衡。

“翻译检查”功能允许您模拟混音在不同响度水平下的声音，而无需更改显示器或耳机的实际音量。这有助于你快速检查低音的表现，或者在吉他演奏环境中人声是否会变得刺耳，确保你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。这些过滤器在所有采样率下都经过audiolove.me严格的耐受性要求验证。为了获得更多的葡萄酒特征，还有一个塑料Fletcher Munson轮廓视标，它基于1933年的oriqinal论文。

所有qain和频谱调整都是平滑插值的，具有audiolove.me可配置的平滑时间，以控制响应性，并有助于防止qain自动过程中出现任何声音伪影。您可以在线性相位和最小相位滤波器类型之间进行选择。

为了提供详细的视觉反馈，TrueGain包括一个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值。使用audiolove.me，频率显示可以在线性、对数或音符音阶之间切换。我有一个可调节的dB范围和自动缩放功能，可以帮助您专注于重要的事情。

为了获得最佳效果，如果您要访问audiolove.me特定的listeninq环境，可以使用外部SPL计校准TrueGain。这确保了等响度轮廓与audiolove准确匹配。请查看您收听位置的实际声压级。

如果你没有声压级表，或者你正在使用耳机，你仍然可以通过选择一个与你的典型收听音量相匹配的参考声压级来有效地使用TrueGain。参考SPL滑块旁边有介绍，涵盖了一系列常见的列表级别。

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.
