Understanding of Discrete Fourier Transformation (I) ------ the origin of Fourier Transformation: The description of Fourier transformation can be easily found in books or on the Internet, but it is mostly an article about it, it's too abstract.

When developing a call center, you need to play the voice. You need to convert the wav format of your recorded voice to the gsm format. asterisk also supports the wav format, however, it is unclear why the wav file cannot be played if it is larger,
