From 96-24 to 44-16

Post by msnickybee »

Who's knowledgeable here in Mastering?

I realise SPAN isn't the best freq analyser (BlueCat does show the same tho'), but any ideas why rendering (using MixCraft "midown") from my 96/24 master to 44/16 with no VSTs present should show such a frequency bump after 20k?
(given that I purposely smoothed/low passed this area when creating the master as you can see)

Same part of song shown, and this bump is consistent throughout. I've experimented with TB-Barricade and it's dithering & noise control etc with no luck. Artefacts?
I'm missing something pretty stupid and basic here, I know it......

(If I render my original mix project to 44-16 in the first place, the same occurs)

This could be a reverb tail or some other trailing sound that you can't hear. You could try blocking all frequencies above 20k with EQ or other vst and then render and see.

I'm blocking those frequencies in building the master, but I also had tried what you said - blocking them just before conversion to 44-16.
I tried a conversion to 96k 16bit (ie reducing bit depth) and that was fine, it was the conversion 96->44 that produced this.....

I read elsewhere that if I was going to end up at 44k (which was always the plan), I'd have been better off recording at 88.2/24, making the conversion easier and less prone to artefacts?
Still not sure what's happened in Mixcraft here.
