lechery (GIS) 于 (Mon Jun 20 10:38:14 2005) 提到:
在windows下面，要进行bit perfect播放，有两个障碍要越过
第一个是remix，第二个是resample
前面一个问题是windows 的kmixer造成的，kmixer是windows下来协调音频同步播放
控制音量，EQ的一套有损算法和界面组成的
通常的说法是，不支持kernal stream或者ASIO的声卡，
或者只要你用了WDM 类型的驱动
无论声卡有什么能力
kmixer一定会把bit perfect破坏，
数据在到达sound card之前就已经被kmixer处理过了，
kmixer背后的有损算法的SN是92db，小于CD
实际中，kmixer在16bit的数据流里面写一些垃圾数据，使得bit精度下降到14bit
还有一个原因可能是kmixer无法做100％的unity gain造成的
至于为什么kmixer不能老老实实的leave 44.1khz的stream alone呢？ |

发帖数: 16 | 11 小弟最近看cracking the coding interview 第五版上关于bit manipulation的内容，
有些不解。因为这本书的code基本是用java写的，所以我默认书上介绍的operators也
是java里的。
可是这本书介绍right shift operator时，只介绍了‘>>', 而且书上的例子是向右移
位后在左补0.
可我看JAVA DOC上写的，JAVA实际上有两种right shift operator, '>>' 和 '>>>',实
际上‘>>’移位后补的是整数2进制补码的sign bit，>>>才是无论怎样都补0.
请大牛们指点一下，我的理解是否正确呢，书上的内容是否有误？
另外想请教一下，是不是真正面试的时候即使有bit manipulation的内容也很少用java
考，一搬C\c++考的比较多吧？ |

发帖数: 7227 | 28 sorry more questions on byte boundary access,

9.4.4 Memory Access
The ARM9EJ-S core supports byte (8-bit), half-word (16-bit) and word (32-bit
) access. Words
must be aligned to four-byte boundaries, half-words must be aligned to two-
byte boundaries and
bytes can be placed on any byte boundary.
so for the case of (int *)(&array[1]),
it's still treated as int, which must be aligned to four-byte boundaries.
