Setting your project sample rate is one of the first things you should do before you begin recording audio. If your project consists only of software instruments and MIDI, you can change the sample rate at any time. But when audio is included in your project, changing the sample rate will require your audio to be converted to the new sample rate.
Logic Pro is capable of converting your audio to any sample rate, but this processing introduces the potential for degradation. Strive to capture clear recordings that need little processing. Beginning your project with the correct sample rate will help you achieve this goal.
If you must change the sample rate, downsampling (converting the sample rate from high to low) is preferable to upsampling. So start your projects with as high a sample rate as your hardware will allow or the project requires. The downsides of very high sample rates are larger file sizes and additional hardware processing. Your computer can’t hold as many tracks or effects plug-ins on a project with a higher sample rate.
To set your sample rate:
Choose File→Project Settings→Audio.
The Project Settings window opens to the Audio pane.
In the Sample Rate drop-down list, select the sample rate.
Logic Pro supports the following sample rates: 44.1, 48, 88.2, 96, 176.4, and 192 kHz.
CD audio uses a sample rate of 44.1 kHz and is ideal for most situations. For video production, 48 kHz is common. Higher sample rates are usually reserved for audiophile recordings, such as classical music and DVD audio. However, as hardware and processing power improves, higher sample rates may become more common.
