Topic: Izotope RX Advanced resample???

[kirk97132]

I am wondering if anyone can explain the differences in the settings and how the affect the sound when doing resampling.  To my ignorant untrained self it would seem that a setting which most closely matches the ideal filter would be best.  Yet it has a default setting which is sort of middle of the road.  I can't really tell a difference by listening so I'm wondering if it is the artifacts left behind or something like that.  Is there anything to be gained by using the ultra steep setting, or better yet is there any thing to be lost.  Thanx in advance for educating my dumb ass, Kirk

Edited to add that I use the standalone Izotope RX Advanced, not the standard version or the plug in if that matters

Since when does iZotope RX resample, and how do you do it?  I know it will dither, but have not been able to figure any way to change a files' sample rate.

I use a standalone RX Advanced version I don't think the standard version does it.  Sorry, I edited my post to reflect this.

I just have the standard version of Rx but here's my shot at it.

If the advanced version has true upsampling (not just filling it in with zeros) than, just like some of the better equalizers which upsample before it's applied (smoothing out the curves) I would imagine that Rx does the same thing and for the same reason (just a wild guess here). If this is the case, you'd only notice a difference when it wasn't being upsampled and it needed to be.

To find out the real poop on it, why don't you just email iZotope. They have guys there to answer questions like this and if you paid for your software, you've already paid your share of their salaries. Why not get your moneys worth?

I am actually looking for downsampling. And if the engineers answers and references had made sense I wouldn't be here looking for a laymans explanation.
