Sound Card
Your sound card must support the 16bit/44.1kHz standard ("CD
quality"). Recording at lower than 16bit resolution is not possi-
ble, due to Logic fun's professional audio quality requirements.
This also applies to the 44.1kHz sampling rate. Other sampling
rates are not supported.
Full duplex or Overdub Mode
Ensure that your chosen sound card supports "full duplex" or
"overdub" mode. "Full duplex" means that the soundcard is
able to record, while playing back at the same time. This ability
is really mandatory, even for the most basic of recording appli-
cations.
If you are still undecided on which soundcard to choose for your
system, its full duplex ability should be one of the most impor-
tant considerations.
If your current card does not support full duplex, you may be
able to upgrade it using a more recent driver (depending on the
hardware, of course). Be sure however, that it meets the 16bit/
44.1kHz requirements for both recording and playback.
If your card supports full duplex, but only allows recording at
lower than 16bit resolution, your recordings will suffer from
poor sound quality. In this case you should disable full duplex
operation using the "Logic Audio Device Setup" program (see
page 26). This does mean that simultaneous playback is now
disabled during recording, but Logic fun will now record at the
full 16bit resolution—you really owe it to your ears.
