26 Chapter 2 Recording
To set the project sample rate:
m Choose File > Project Settings > Audio (or use the Open Audio Project Settings key
command), and choose the desired sample rate in the Sample Rate menu.
To set the basic project tempo, do one of the following:
m Click-hold the Transport tempo value and drag up or down.
m Double-click on the Tempo field in the Transport, and type in a new value. Press Return/
Enter, or click outside the Tempo field to exit the dialog.
The project tempo is primarily of interest for MIDI recording, but it also impacts on the
metronome, which generates the click sound heard during the count-in.
The Importance of the Sample Rate
Digital audio needs to play at its original sample rate, or be converted to a different
one, before playback at another sample rate. To explain; when a file which was
created by sampling 96,000 times per second (96 kHz sampling rate), is played back
in an application that is set to a sample rate of 48,000 samples per second, it will play
back slowly (half the speed).
Commonly used sample rates include 44.1 kHz for CD quality audio and 48 kHz for
audio files used in digital video productions.
