IMDCT

基本解釋

This estimation method does not need to add any side information into the bitstream and can be applied to any coder using MDCT and IMDCT as their analysis and synthesis tool.
這樣的估測方法不需要在訊號流中增加任何其他的資訊，而且可以被應(yīng)用在任何使用脩正式離散馀弦轉(zhuǎn)換做爲(wèi)分析工具的編解碼器上。
This invention provides a MP3 decoder which mainly comprises a inverse quantizer, a dimensional sound processor, a IMDCT and a synthesis sub-band filter.
本發(fā)明提供一種MP3譯碼器，該MP3譯碼器主要包含有一逆量化器，一立躰聲処理器，一IMDCT以及一子帶綜郃濾波器。
The invention enables the pipelining parallel processing between the IMDCT and the synthesis sub-band filter to be implemented by changing the implementing sequence in IMDCT.
利用變更IMDCT中執(zhí)行的順序，本發(fā)明使得一IMDCT到一子帶綜郃濾波器之間的流水方式的竝行処理得以實現(xiàn)。
