I'm not sure about the asf format, but the wav format definitely does support 24/96 audio.

For multichannel audio the situation is a little less clear. Microsoft claims that the standard wav format only handles up to 2 channels, and they created a new extension called WAVE_FORMAT_EXTENSIBLE to properly handle more than 2 channels with unambigious channel assignment. It's not universally used, however.

ASF also supports 24/96. WMA Pro (like all the Windows Media audio and video codecs) is placed into the ASF container, even though it has a .wma extension. WAVE as a format is disorganised as hell, it's really dependant on what the application you want to use supports in regard to multichannel. Most just use a mono wavefile for each channel. This page claims multichannel support is standard compliant.
