If you look at the beginning of 'encoder.h', some of your questions will be answered.

in the encoder.h its written like

* polyphase 256-16            (dec or enc)        = 240
* mdct      256+32  (9*32)    (dec or enc)        = 288
* total:    512+16
*

i didnt understand this calculation..please help me
