在音頻/語音編解碼器,正交鏡像濾波器對經常被用來實現一個分成兩個頻帶分割的輸入信號的濾波器組。
將得到的高通和低通的信號往往是減少了2倍,給臨界採樣的原始信號的兩通道中的表示。
相關的時間序列翻轉的係數的順序,因為是線性濾波器的卷積,所以都具有相同的指數在這個總和。與此屬性的過濾器的一對被定義為正交鏡像濾波器。

我写一个免费的图象音频编码器,
i writing an free losless audio coder,
faster on old 486 than
flac or ape decoding on pentium 233 MHz !!!
the program working, and compression ratio is equal to flac / ape ...
On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :)
approx 14 sec coding enya.wav with pkzip, and my routines not have completed.
My hope is 4 sec compression time, if completing,
and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!!
PLEASE HELP ME !
i am an hungarian programmer, and i cannot wrtite in english perfectly.
i not have time for write code for
incoming 16 bit variable contents !
i want variable bit size putting into 8 bit foam.
the 16 bit variable containing e.g. 7 bit valuable data,
and 8 of this data must be storing into 8 bit datas.
(code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder,
