DCT_IDCT
to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression
for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution
now compare our special 8X8 functions with the internal general functions
use this code:
A = int32(100*rand(8,8))
tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc
tic for i = 1 : 1000 idct2(dct2(A)) end toc
i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

這是一個讓原始音訊可以再不改變音訊長度下,改變pitch的程式,因為如果音訊用resample,雖然可改變其音訊頻率音高,但是卻會有拉長音訊的副作用,因此設計了一個可以改善其缺點的小方法(實做paper )(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))
