What's the point in using ASIO for audio playback?

    he actually posted some supposedly jitter improvement measurements: cMP² | CMP / 03Jitter

    I think most of his HTPC building advices are really great, but they're good to follow if you're a perfectionist...I don't really expect any SQ improvement(which is great BTW on my setup at this point [​IMG])

    I even read the xxhighend(another smokey player) coder on computeraudiophile.com(which is filled w/ ppl who believe in the most ludicrous things) saying that he cannot stand the sound of ASIO and prefers WASAPI by far.

    when you start comparing bit-perfect audio renderers, something REALLY isn't right IMHO [​IMG]

    except for a bad implementation of course, like xbitlabs mentioned here: Universal Soldier: ASUS Xonar D2 PM Sound Card Review (page 9) - X-bit labs

    that's the thing, a poorly coded windows driver can totally ruin any bit-perfect audio renderer.....like the Asus soundcards that resample ASIO/DirectKS if the fixed sample rate in their drivers doesn't match the file you're playing, they don't offer any bitmatched playback whatsoever.

    so a wonky ASIO/DirectKS miniport implementation can indeed sound bad....can't tell about WASAPI, but it needs WaveRT drivers to really shine I think?

    These don't really say much about the cMP/cPlay tweaks though, since there are no measurements without cMP/cPlay. Also I would expect a jitter analyser to be used instead of inferring jitter from frequency response.

    Agreed...
