APU频谱分析仪是一款免费的频谱分析工具，支持多种FFT配置选项。您可以根据需要调整FFT窗口类型（矩形、汉宁窗、汉明窗、布莱克曼窗、凯撒窗）和大小（从64到65536）。实时监控频谱，并可调整历史记录长度，或加载外部文件进行完整频谱分析。

快速切换标准dB量程或自动量程，并以对数、线性或音符刻度查看频谱。支持直方图保持功能，用于测量长期频率响应。您还可以独立于FFT大小调整桶大小，并拍摄频率响应快照以供参考。

APU Spectrum Analyzer is a free spectrum analysis tool supporting a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 up to 65536) to suit your needs. Monitor spectrum in real-time with variable history size, or load an external file for full spectrum analysis.

Quickly switch between standard dB ranges or auto-range and view the frequency spectrum in log, linear, or note-based scale. Supports histogram hold for measuring long term frequency response. You can also adjust the bucket size independent of the FFT size and take snapshots of the frequency response for reference.
