    Using 48khz sample rate with 44.1kz samples
    Hi Rounik I have a new audio interface that lets me record at 48khz sample rate. I'll be recording bass and vocals so I think I should take advantage of the higher rate. But the rest of the music is supplied by loops which are all 44.1kz. If I set the project sample rate to 48khz, apart from the warning dialog box is there anything bad that will happen to the 44.1 khz loops? Thanks Rounik - PS I'm working on getting that project up, not long now! Hamish

    Hi Hamish, In the Audio Bin, if Logic doesn't automatically convert your audio files to 48Khz, you can select them and choose Copy/Convert files... Keep all the settings the same but change the sample rate. It's important that the sample rate of all audio files used in your project match the project's sample rate... otherwise they will playback at a different speed. I'd like to make one point (you might prefer to skip over as it's my opinion). Why are you going to record at 48k? I only record at 48 if my project is destined for film/video or has been specifically asked for in that format. Otherwise, IMHO, the benefits of recording at 48 for a CD project that needs to be converted to 44.1 anyhow are minimal. Also, Logic's Apple Loops can act a little weird when used in projects of higher sample rates... Can't remember if that's just for 96k or if it affects 48k projects too... Sorry if it feels like I'm raining on your parade... I don't intend to discourage you from trying it out and finding what works best for you! ;-)

    Great advice, thanks Rounik. I guess I'm just keen to take advantage of some new gear - and there is a school of thought (including some of the MPV trainers) that thinks recording at the highest sample rate possible is best. I thought I'd try out my bass on a couple of different sample rates to see which one got the best sound, but I don't want to destroy my projects in the process! I don't make music for film/tv, and to be honest 44.1khz has been fine for my ears since the 1990s, so I'm not too attached to the idea of 48. Do you think it would make a difference to recording vinyl into logic (for eventual conversion to MP3)? Or would that be minimal too? H

    Yes, very true... record at the best quality possible... but then the A/D converters, monitors and room acoustics being used become more important in my mind. I spent a while recording and mixing in 48 a while back, but (for me) didn't notice any hugely perceivable difference and was aware that the built-in algorithms used to convert from 48 to 44.1 are apparently not as good as when converting from say 88.2 to 44.1 or 96 to 48. Apparently whole number conversions work better... Again, I've not really got too involved in the detailed science behind this - but just gone with my ears. I don't think recording vinyl at 48 would give you any benefit, especially as the end product is an mp3. There would definitely be real benefit in recording audio at 24 bit depth. A higher bit depth will allow you to record at lower levels.... :) Rounik

    No probs Hamish! You too. Have a great day no matter what sample rate you use ;-) R
