DFT的matlab源代码频谱图 提取音频信号（wav）并将其转换为频谱图。 用Go编程语言编写。 安装 git克隆 例子 python3 sine_wav.py && ../../xigh/spectrogram/spectrogram -hamming -hideavg -bins = 256 sine.wav 用法 ./specgramgram [options] input_file.wav -preemp float64 set pre-emphasis parameter (0 means no pre-emp) -rectangle disable hamming window support -BG0 string set background color 0 (default "000000") -BG1 string set background color 1 (default "333") -BG2 string set background color 2 (default "447744") -FG0 string set forground color 0
