Sample rates


Recommended Posts

You might be confusing sample rates and bit depth here.

Typical sample rates for audio files are 44.1KHz, 48KHz, 96KHz.

Typical bit depths for audio files are 16-bit, 24-bit, 32-bit and 32-bit float.

(48-bit audio files aren't a thing, as far as I know.)

Logic will convert anything it can't natively handle directly, so you don't generally have to worry about it too much, but I'd stick to the same sample rate if you can to avoid unnecessary sample rate conversion. Bit depths don't really matter, all audio will be rendered through the mixer at the same bit depth anyway.

Is it more taxing for your computer to have different audio files playing back in the project with different sample rates?

No, it's not more taxing for the computer.

However all audio files should be at the same sample rate as the project's sample rate, or they will be played back at the wrong speed (wrong tempo) and wrong pitch - just like reading a 45rpm record at 33rpm. 

For example if you play back a 44.1 kHz file in a project that is set to 48 kHz then it will be sped up and pitched higher by a little over a semitone.
