Thing with the new E-mu cards - not advertised and not "found out" in any review I've seen, is that they are very poor for MME - you have to have an ASIO program such as Cubase to get all the channels and although MME has 24bit, it goes no higher than 48Khz. So E-mu is a no-no for Cool Edit Pro/Audition for instance - unless 2 in and 2 out is all you need.
Compared to the Audigy, the E-mus come out well ahead on audio quality, but do remember they are no good for game sound and do not have midi synths.
Isn't that more a function of MME than a problem with E-Mu, per se? MME drivers aren't designed for serious audio work.
See below:
ASIO
ASIO stands for Audio Stream In/Out and is a technology created by Steinberg, the company responsible for the Cubase recording software product. ASIO, like DirectX, was designed to reduce latency by providing direct access to hardware - specifically, sound cards. ASIO 2.0 is the latest version, which provides some additional features such as hardware sharing between applications and enhanced audio/MIDI synchronisation. Generally speaking, ASIO is really only utilised in professional audio and music applications, although some MP3 DJ software supports it due to the associated low latency. ASIO is supported in Windows 9x, Me, NT, 2000 and XP and can provide latency as low as 2-10ms.
MME
MME stands for Multimedia Extensions and was introduced as part of Windows 3.0. This is an old technology, available only on Windows 3.x, Me and 9x. Although recent versions of MME drivers can compete with DirectX in terms of latency, MME drivers should only be used where DirectX drivers are not available. Usually, MME drivers provide about 300-1000ms latency.
WDM
These Windows Driver Model drivers are a more recent addition to Windows 98, Me, 2000 and XP. They are often ‘translated’ from DirectX or MME drivers. Although this often introduces 30ms or more extra latency, some WDM drivers can provide latency under 10ms, making them a good alternative to ASIO, for example.
