短時距傅立葉變換（Short-time Fourier Transform, STFT）是傅立葉變換的一種變形，也稱作加窗傅里叶变换（Windowed Fourier transform）或Time-dependent Fourier transform，用於決定隨時間變化的信號局部部分的正弦頻率和相位。實際上，計算短時距傅立葉變換的過程是將長時間信號分成數個較短的等長信號，然後再分別計算每個較短段的傅立葉轉換。通常拿來描繪頻域與時域上的變化，為時頻分析中其中一個重要的工具。 網頁ASTFT Algorithm For this situation, m is discrete and ω is constant, however Algorithm for the Adaptive STFT is: in most common applications the STFT is performed on a Set …
