免费福利：Visu - 实时可视化音频频谱分析插件
VISU
Visu is a real-time spectrogram plugin for audio analysis and visualisation.
A spectrogram displays how the frequency content of a signal changes over time, with amplitude represented by colour. Think of it as an audio X-ray, useful for spotting transients, analyzing pitch and harmonics, detecting unwanted noise, and tracking how a sound evolves.
Alongside a classic spectrogram mode, Visu includes an enhanced mode with greater precision in both time and frequency. It uses time-frequency reassignment (a technique that relocates energy to its most accurate position using phase information) resulting in sharper transients, clearer pitches, and a more detailed image.

Visu Visu 是一个用于音频分析和可视化的实时频谱图插件。 频谱图显示信号的频率内容如何随时间变化，幅度由颜色表示。 将其视为音频 X 射线，可用于发现瞬变、分析音高和-Xie波、检测不需要的噪声以及跟踪声音的演变方式。 除了经典的频谱图模式，Visu 还包括一个在时间和频率上都具有更高精度的增强模式。 它使用时频重新分配（一种使用相位信息将能量重新定位到其最准确位置的技术），从而产生更清晰的瞬态、更清晰的音高和更详细的图像。 主要特点 经典和增强的频谱模式 冻结和 PNG 导出 HIDPI 支持 线性和对数频率尺度 可调节 FFT 大小 滚动或静态绘图模式 光标下的频率读数 完全可用的免费版本（黑白） 40 多种彩色图（色盲友好）
