New Video on Resampling

3/11/2015

 
I thought I was done with 'Just the Two Of Us' 192 kHz HD Tracks version, but when I noticed that the intersample peaks on the 44.1 kHz version were above the sample peaks, I had to figure out what was going on.  Basically when you resample from 96 kHz to 44.1 kHz, the distance between the samples and the shape that the samples are making combine to occasionally make an inter-sample curve that is above the sample level.  It was mildly shocking to me that it was .3 db!  I was not expecting that.  I ran hundreds of tests of different settings and then went in to see the waveform resample.  I took pictures of it and I hope that you can see what I saw.  The bottom line is that it is another reason to stay 1 decibel away from the 0db ceiling.  Next time we will look at something totally different (I hope).  Until next time...
