说明： 一個音樂分頻程式，以c++寫成。內含一個將音樂轉成純數字的源碼，一個分頻源碼(用FFT的overlap-and-add技術寫成)，一個把不同頻率加起來的源碼(確認分頻正確)。
(A filter bank using FFT overlap-and-add with a transformer that transfer the wav file into txt file and a checker that ensure the filter is correct.)

filterbank.cpp (7118, 2009-11-23)
transToNumber.cpp (667, 2009-11-26)
addData.cpp (1486, 2009-11-26)
transToNumber.cpp: to transform a wav file into txt file with its contents.
filterbank.cpp: use FFT with overlap-and-add method that can perfectly seperate
the data into different frequency band without any distortion.
addData.cpp: sum up the data which are the outputs of filter bank.
