Creating a New Project
4. Click on the Key box in the First Beat or the Other Beats section.
5. Play a note on your MIDI instrument. The note number is entered
automatically. The velocity is not updated.
6. Click OK.
Your metronome settings will be saved with the project file.
Setting the Audio Sampling Rate and Bit Depth
Each project has an audio sampling rate and an audio driver bit depth
that indicate the level of accuracy with which audio data are sampled and
processed. The same parameters are used for all the digital audio in a
project. When you create a new project, if you do not want to use the
default setting, you must choose a sampling rate before you start recording
audio.
SONAR lets you choose from several different sampling rates: 11025 Hz,
22050 Hz, 44100 Hz, 48000 Hz, 88200 Hz, 96000 Hz, 176400Hz, and
192000 Hz. The default used by SONAR is 44100 Hz, the same rate as
audio CDs. However, you may choose a higher rate and later mixdown to
44100. You can also enter any hardware-supported value in the Sampling
Rate field. Consult your hardware documentation for supported sampling
rates.
Note: For most sound cards, all digital audio in the same song must be at
the same sampling rate. Some dedicated audio systems let you mix
different sampling rates in the same song; SONAR only lets you do this if
the audio system supports it. This feature is meant primarily for sound
cards that use different Windows drivers for input and output; SONAR
treats such cards as two different programs.
A higher sampling rate produces better quality sound. However, a higher
sampling rate also means that each audio clip takes up more memory and
disk space and requires more intensive processing by your computer. If you
have an older computer, or a slow hard drive, you might be better off with a
lower sampling rate. For more information, see Improving Performance with
Digital Audio.
By default, the audio driver 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 file or another digital audio file, the sampling rate
