Creating a New Project
Recording
and audio driver bit depth of the wave file are converted to your default
setting, if necessary.
Note: 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 and bit
depth to match the target unit. For example, use 44,100Hz/16-bit for a
project that will be mastered to a CD, so that no sample rate conversion is
required.
To Set the Sampling Rate and Audio Driver Bit Depth
for New Projects
1. Choose Options-Audio to display the Audio Options dialog box.
2. On the General tab of the dialog, select a value in the Sampling Rate
dropdown menu, and a value from the Audio Driver Bit Depth dropdown
menu.
3. Click OK.
The sampling rate and audio driver bit depth are saved with the project file.
Setting the MIDI Timing Resolution
Each SONAR 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 960PPQ, which is accurate enough for most
applications. In this timebase, each quarter note is represented by 960
ticks, each eighth note by 480 ticks, each eighth-note triplet by 320 ticks,
and so on.
In some projects you may need a different timebase. For example, if you
wanted to use eighth-note septuplets (7 eighth notes per quarter note) and
represent them accurately, you would need to have a timebase that is
divisible by 7, such as 168PPQ. SONAR uses the timebase you choose for
a project to determine the range of tick values in the Now time.
To Set the Timebase for a Project
1. Choose Options-Project and click the Clock tab.
2. Choose the timebase you want from the Ticks per Quarter Note list.
3. Click OK.
The timebase will be saved with the project file.
