JAKE'S EHPRA 2.0

The odd thing I noticed with VLC is that sometimes playing the ultrasonic subliminal track for the first time in a while will cause crackling. However, click stop and then start the ultrasonic track again on VLC and it plays smoothly with no crackling.

In addition, if you play at lower volumes with no crackling (as I am) it should not be a problem. I simply avoid putting the volume at a loud level. With VLC at 2-3 out of 16 is enough to get -40db on Frequensee, which is around the recommended level.

I know my brain is receiving the input, so I don't think it's something to worry about. (I use MacBook Air)

Update: I looked up the maximum frequency for Macbooks and they are 20khz across their product line.

thank you Lowe

So even at 20khz across their product line, I get the crackling.

I have been playing at 80-90% volume on iTunes in the hope it reached my ears. But you're saying bring the volume down until I hear no crackling when I put my ears to the speakers, yes? ill retest frequensee do i do it using my phone next to my ear or next to the laptop speak (which is where the monitor and keyboard join)?
