電腦放音樂勝CD機???

我認為最重要是
從硬碟中的WAV檔轉成PCM的過程
應該是CAT好不好聲的關鍵
這涉及到優化及OS
成敗都在這

PCM （pulse code moudulation）http://en.wikipedia.org/wiki/PCM

A PCM stream is a digital representation of an analog signal, in which the magnitude of the analogue signal is sampled regularly at uniform intervals, with each sample being quantized to the nearest value within a range of digital steps.

以固定之時間間隔記錄記錄類比訊號振幅之手法

WAV（Waveform Audio File Format） http://en.wikipedia.org/wiki/Wav

The usual bitstream encoding is the linear pulse-code modulation (LPCM) format.

一般WAV檔用編碼手法都是LPCM。

LPCM (linear pulse-code modulation) http://en.wikipedia.org/wiki/Linear_...ode_modulation

The term pulse-code modulation (PCM), though strictly more general, is often used to describe data encoded as LPCM.

嚴格說，PCM較廣義，但一般常用PCM稱LPCM。

以上，Wikipedia內容總和 -- WAV檔內的資料格式就是PCM



優化？ http://records2ear.blogspot.com/2011/11/dac_28.html
