用惯RME的ASIO,当然会觉得别人的不好了……论ASIO性能,有几个卡能是RME的对手?
至于KS,微软在音频方面还是说不上话啊。
Windows Driver Kit: Audio Devices
Introduction to WDM Audio Drivers/ E& q0 }# d, j. v" k
Kernel streaming (KS) services support kernel-mode processing of data streams for audio and for other types of continuous media. Conceptually, a stream undergoes processing as it flows along a data path containing some number of processing nodes. A set of related nodes is grouped together to form a KS filter, which represents a more-or-less independent block of stream-processing functionality. More complex functions can be constructed in a modular way by cascading several filters together to form a filter graph.2 O- ?+ ^/ ]: i) M$ b5 ]

A typical audio adapter card might contain audio devices for playing a wave stream through a set of speakers, converting the audio signal from a microphone to a wave stream, and synthesizing sound from a MIDI stream. The adapter driver can wrap each of these audio devices in a KS filter that it exposes to the operating system. The operating system connects the filters to other filters to form filter graphs that process audio streams on behalf of application programs.5 t' T7 c! }" e
KS filters are connected together through their pins. A pin on an audio filter can be thought of as an audio jack. A client instantiates an input or output pin on a filter when the client needs to route a data stream into or out of that filter. In some contexts, the terms pin and stream can be used interchangeably.0 n6 e. E. E/ n, w
- I$ Y8 ^% e% l, l3 I
The output pin of the upstream filter is connected to the input pin of the downstream filter. The data stream from the output pin must have a data format that the input pin can accept. Data buffering is typically required to smooth out momentary mismatches in the rates at which an output pin produces data and an input pin consumes it.) o3 ]7 [. I3 ]% q
A KS filter is implemented as a kernel-mode driver object that encapsulates some number of related stream-processing functions. The functionality can be implemented in software or in hardware. In this model, an audio adapter can be viewed as a collection of hardware devices, and the adapter driver exposes each of these devices to the audio system as an individual filter. ]5 e7 D+ ]- X+ I9 p8 Q% y

An adapter driver exposes a collection of filter factories to the audio system. Each filter factory is capable of instantiating filters of a particular type:6 O g$ B( x6 z: ]3 C$ B+ n! x+ S: ~
If the adapter contains one or more devices that are similar or identical in function, the driver groups the filters for those devices together into the same filter factory. ! ^5 z u" [" z
If the adapter contains several different types of devices, those devices are presented through several different filter factories. * Y+ P/ } U6 e3 ^: X
A KS filter exposes a collection of pin factories to the audio system. Each pin factory is capable of instantiating pins of a particular type. If the filter can provide one or more pins that are similar or identical in function, the filter groups those pins together into the same pin factory. For example, a filter that performs audio mixing might have one pin factory that can instantiate a single output pin and a second pin factory that can instantiate several input pins.

KS services are built upon the Windows Driver Model. Note that the term KS filter must be distinguished from the term filter driver, which is another WDM concept. A filter driver resides in a WDM driver stack and can intercept and modify the I/O request packets (IRPs) that propagate through the stack. Upper- and lower-level filter drivers reside above and below the function driver, respectively. In this section, the term filter refers to a KS filter rather than a filter driver unless noted otherwise. For more information about filter drivers, see Types of WDM Drivers.

另外,对于foobar用KS输出中系统会挂掉的事,我认为这不一定全是Maudio的问题。7 \/ g- Z9 b, o) l
也许foobar的KS输出本身的错误处理就做得不好,从而把系统整挂。内核模式的处理稍有不当,弄垮系统是很容易的。所以在vista上, ...

这个不出奇,毕竟FB也提示说KS输出不稳定了,不过蓝屏后系统显示导致出错的原因到是delta的驱动:wacko:
