To set the project sample rate:

To set the project sample rate:

mChoose File > Project Settings > Audio (or use the Open Audio Project Settings key command), and choose the desired sample rate in the Sample Rate menu.

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.

To set the basic project tempo, do one of the following:

mClick-hold the Transport tempo value and drag up or down.

mDouble-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.
