The Quadra's sound input is 8-bit linear PCM with analog limiting to
enhance the power of the signal being digitized. The sample rate may be
22kHz or 11kHz. Therefore, to achieve 44kHz input, you'll need to obtain
third-party hardware and software tools, such as those from Digidesigns,
Inc. Information on Digidesigns' offerings may be found in buyer's
guides, including the electronic buyer's guides on AppleLink.
