HI guys, this is Mike. So I was thinking and messing around today and preparing sound files for a DAC vs DAC null test. Here is what I did.
1. Created a audio file with pink, sine, and sweeps
2. Tested to see if my built in realtek soundcard could capture the same file multiple times to get a null.
(I did this in audacity at 24bit/48khz sample. I flipped polarity to test for null.)
Step 2 is where I failed. No matter how many times I recording my test audio into the PC they were too different to get any null, just a weird phasey VERY partial null.
Now before you guys knock me for using a stock soundcard, I had a full 16 track studio set up before but sold of almost all me gear when my family was dealing with cancer, so now I have no mics/interfaces.
What I am wondering is if anyone with a higher quality recording interface is able to recored a sound sample and get it to null between 2 captures. If not then it seems a null test is useless?
And if the sound is never the same twice does that mean the music we here is also so different each time!?
Thanks for the help.
And I did align each file to the sample.
