48,000 Hz Retroactively?

Post by ReganO » Fri Mar 10, 2023 2:45 pm

Hey All,

I'm a newbie and it's my first time posting - so be gentle.

When using GarageBand, can I retroactively apply 48,000 Hz (using Audio MIDI set-up, of course) to my project if I forgot to apply it initially. This is a project in-the-works; I'd rather not have to cut and paste everything into a new project just to make the correction.

10Q,

ReganO

Well yes and no. Of course you are able but shouldn't. I t will not sound as good, you loose a little of the high frequencies and transient in the wave file. It's like taking a photo from a 1080 p format and rendering it out to 8k, yes the app will but results will be terrible.

You can render down from a 48Htz to 44.1 or mp3 but not good the other way around for those who have supersonic BAT ears and can hear the difference.

That is why libraries that master the tracks themselves will say "if you have already recorded in 44.1 K do not render to 48 k we will take care of it"

I have gathered this info from other professionals and youtube just in case others disagree .

Hope this helps

If the Project is 44.1k and a Publisher is asking for 48k then just set it to that when you do the final file export - It will be fine as there really isn't much if any audible difference. Don't sweat it.

I convert 44.1K wav/aif to 48K wav/aif all the time and there is no audible difference to mortal ears. Over the years (too numerous to mention!), many times I've been given a 44.1K from a producer and then a library asks for 48K. I convert and it's fine.

What you shouldn't do is convert an mp3 to wav/aif since once the audio is compressed to mp3, you can never get the lost info back.

Thanks All!

I'll try the "convert it when exporting" option.

I really appreciate it! :)

Hi Mark and fellow Forumees

Was just wondering what's your thoughts on were the ideal recording settings on your Daw rather then export settings should be. Do you record in 32/24/16 bit and 44.1, 48, 98, 192 hz sample rate. As there is a bit of trade off in Daw performance and track count, especially on older rigs going to the higher rates, I wonder if it really going to make or break a project for tracking purposes if you can later bounce out to what ever you want and nobody notices the differences?
Mine is set 44.1k 24bit

I mean if you were recording a world class violinist playing a stradivari in a well treated acoustic space and a high end mics & pre-amp then mixing it through a Neve or SSL to SACD and playing it back on a £100k's worth of Hi-FI equipment then sure. Record it at 192k.

For library work there are many many factors outside the recording specs that make significantly more difference ( i.e. Can you write - play - mix - master to broadcast quality ? ) than any perceiveed fidelity difference between samples rates & bit depth.

Try this blind test to see if you can reliably tell the difference between Wav & MP3

OH no !, Please no more of that religious stuff again. As much as I do respect your faith in the tooth fairy too, to me there is no such thing, To me its all just broadcast bullshit by all the best professional bullshitters money and power can buy you :( your views my differ and that's ok if freedom of/from religion is still allowed in the temple of taxi.
As a devout atheist I don't do religion - unless it's hokey ones to do with lazer swords and floating rocks.

Broadcast quality is just a term Michael Laskow lifted from an advert for camcorders. It's clever because it's less of a technical standard and more of an aesthetic one.

Your 192k 32bit floating point super HiFi cue still won't get on air if the samples are dated and the music sucks. But an MP3 of a great cue may well do if that's all they have.
