on page 13-20.
By default, the bit depth of audio data is 16 bits. If your sound card
supports 18, 20, 22, or 24 bit audio, you can choose to take advantage of
these higher resolutions.
If you are creating a new project that will contain only MIDI material
(no audio), you do not need to set the audio sampling rate or bit depth. If
you import audio from a wave Þle or another digital audio Þle, the
sampling rate will be set automatically to your default setting.
Note for Experts:
If you are planning to move your project to a Digital Audio Tape
(DAT) or to some other media via a digital transfer, set your sampling
rate to match the target unit. For example, use 44100Hz for a project
that will be mastered to a CD, so that no sample rate conversion is
required.
To Set the Sampling Rate for a Project...
1. Choose Options-Audio to display the DirectShow Audio dialog
box.
2. Select the desired sampling rate from the Default Sampling Rate
list.
3. Set the desired bit depth in the Default File Bit Depth box.
4. Click OK.
The sampling rate will be saved with the project file.

Setting the MIDI Timing Resolution

Each Pro Audio project has a setting for the timing resolution, or
timebase, that indicates the resolution of MIDI data. This resolution is
measured in ticks or pulses per quarter note and is often abbreviated as
PPQ. The default resolution is 120PPQ, which is accurate enough for
most applications. In this timebase, each quarter note is represented by
120 ticks, each eighth note by 60 ticks, each eighth-note triplet by 40
ticks, and so on.
